I tried this in a Mac app and found that it is full of UIKit code. If you are intending it for Mac Catalyst apps only, then update the README to say macOS Catalyst, not macOS.

In the standard Apple sheet, one can have a NavigationView inside the sheet, the same should be possible with PartialSheet.

In the code example below, you can see the behavior difference, in particular, in PartialSheet all actions become non-responsive when the NavigationView is open.

import SwiftUI
import PartialSheet

struct ExperimentAppleSheet: View {
    
    @State var isModalSheetShown: Bool = false
    @State var isPage1Active: Bool = false
    
    var body: some View {
        VStack {
            
            Button(action: {
                self.isModalSheetShown.toggle()
            }) {
                Text("Open sheet")
            }
        }
        .sheet(isPresented: self.$isModalSheetShown) {
            NavigationView {
                VStack {
                    Text("Modal")
                    NavigationLink(destination: Text("page 1"), isActive: self.$isPage1Active, label: {
                        Button(action: {
                            self.isPage1Active.toggle()
                        }) {
                            Text("Go to next page")
                        }
                    })
                }
                .navigationBarItems(trailing: Button("Done",
                                                     action: {
                                                        self.isModalSheetShown.toggle()
                }))
            }
        }
    }
}

struct ExperimentPartialSheet: View {
    
    @State var isPage1Active: Bool = false
    @EnvironmentObject var partialSheetManager: PartialSheetManager
    
    var body: some View {
        VStack {
            
            Button(action: {
                self.partialSheetManager.showPartialSheet({
                    print("Partial sheet opened")
                }) {
                    NavigationView {
                        VStack {
                            Text("Modal")

                                    Text("Go to next page")
                                }

Hi there, thanks for the great library! I really love to use this in my project but I just found some strange animation when using the DatePicker or Picker inside the sheet. This is the screen rec, you can see the sheet is moving up and down while using the DatePicker

And the code is basically this

                    .onTapGesture {
                        self.partialSheetManager.showPartialSheet({
                            print("Partial sheet dismissed")
                        }) {
                            VStack() {
                                Text("Some Title").bold().font(.title)
                                DatePicker("Please select a date", selection: self.$selectedDate, in: ...Date(), displayedComponents: .date).labelsHidden()
                            }.frame(height: 300)
                        }
                    }

Is there any way to fix this? Thx a lot

Can you please update the package ?

The partial sheet looks great. I was wondering whether it is possible to put it on the top of the Tab View. The built-in sheet is covering the Tab View when opening.

Thanks a lot to your project! but when I put my partialSheet on a button which is in a ZStack, and set the alignment .bottomTrailing, but it doesn't work .

the code as follows:

ZStack(alignment: .bottomTrailing){
            VStack{
                Picker("helo",selection: $selectedOption){
                    Text("People").tag(0)
                    Text("Tags").tag(1)
                }.pickerStyle(SegmentedPickerStyle())
                
                List{
                    ForEach(tags, id: \.self){
                        tag in
                        Text(tag.name ?? "")
                        
                    }
                }
            }.blur(radius: addMaterialMode==false ? 0: 1000)
            
            Button(action:{
                self.addMaterialMode = true
            }){
                Image(systemName: "plus.circle.fill").resizable().frame(width: 70,height: 70).padding()
            }.partialSheet(presented: $addMaterialMode) {
                Text("hello")
            }
        }

it shows like this:

I have tried .bottomTrailing .top... but all of those don't work properly
, it can only show in the center of the screen

Hi, I added this package to make half modals as you mentioned in your stackoverflow answer. But seems like sheet is still going upto the top. The options you can specify while creating the partial sheet does not take any boolean value for it or am I doing wrong? My code is below:

import SwiftUI
import Combine
import PartialSheet

struct FriendsListView: View {
    
    @ObservedObject var friendListVM:FriendListViewModel = FriendListViewModel()
    @State var showModal:Bool = false
    
    private func addFriend(){
        self.showModal = true
    }
    
    var body: some View {
        NavigationView {
            List {
                ForEach(self.friendListVM.friends) { friendVM in
                    NavigationLink(destination: FriendsDetailView(friendVM: friendVM)) {
                        HStack {
                            Image(friendVM.profilePicture)
                                .resizable()
                                .frame(width:50,height:50)
                            VStack(alignment:.leading) {
                                Text(friendVM.name)
                                .font(.title)
                                Text("$ 10.00")
                            }
                        }
                    }
                }
            }
        .navigationBarTitle("Friends")
            .navigationBarItems(trailing: Button(action:self.addFriend){
                  Image(systemName: "plus")
            })
            
        }.partialSheet(presented: self.$showModal) {
            AddFriendView(isPresented: self.$showModal)
        }
        
        
    }
}

struct FriendsListView_Previews: PreviewProvider {
    static var previews: some View {
        FriendsListView()
    }
}

The View is looking like below in simulator for iPhone 11 Pro Max

Is there a way to modify the rounding of corners?

Hi,

Nice work.

Just a suggestion:
It would be nice to be able to dismiss the modal from code the same way as a stock modal view. With:

@Environment (\.presentationMode) var presentationMode

and then:

{
  self.presentationMode.wrappedValue.dismiss()
}

Thanks in advance if you consider it.

I'm getting this error when I try and create a custom style. This is after adding PartialSheet using SPM.

I think it's because the PartialSheetStyle Struct needs a public init so it can be called when added as a module?

Hello,

I'm using 2 Swift package for my SearchBar (SWIFTUIX), and Modal (PARTIALSHEET).

When I use the search bar, the keyboard appears and the view is above the keyboard.

Before

When I add .addPartialSheet(style: .defaultStyle())

This might be related to issue #35

The line self.dismissKeyboard() in the code below crashes when dismissing the PartialSheet via a drag gesture if a TextField in the PartialSheet has a keyboard presenting. I haven't looked too deeply into this, but I believe this may be because UIApplication.shared.sendAction(resign, to: nil, from: nil, for: nil) is calling into something UIKit-related that SwiftUI isn't.

private func dragGesture() -> _EndedGesture<GestureStateGesture<DragGesture, DragState>> {
    DragGesture()
        .updating($dragState) { drag, state, _ in
            self.dismissKeyboard()
            let yOffset = drag.translation.height
            let threshold = CGFloat(-50)
            let stiffness = CGFloat(0.3)
            if yOffset > threshold {
                state = .dragging(translation: drag.translation)
            } else if
                // if above threshold and belove ScreenHeight make it elastic
                -yOffset + self.sheetContentRect.height <
                    UIScreen.main.bounds.height + self.handlerSectionHeight
            {
                let distance = yOffset - threshold
                let translationHeight = threshold + (distance * stiffness)
                state = .dragging(translation: CGSize(width: drag.translation.width, height: translationHeight))
            }
    }
    .onEnded(onDragEnded)
}

This should be reproducible in a pretty simple use case, but if not let me know and I can try to isolate a sample case.

Thanks a lot!

Keyboard overlaps TextField/UISearchBar

Hello,
I installed it through SPM and then tried PushNavigationExample and an error was reported.

'isPresented' is inaccessible due to 'internal' protection level

This is great work. Thanks for your effort!

I would like execute some code when the user dismisses the sheet. Have you considered adding an onDismiss: closure?

Thank you.

I can't dismiss view with
self.presentationMode.wrappedValue.dismiss()
because I use Partial sheet, not system .sheet
How can I dismiss view which was presented by PartialSheet programmatically?

It would be great to have a style that simply takes a bool parameter for blur to produce the effect shown here:
https://medium.com/@edwurtle/blur-effect-inside-swiftui-a2e12e61e750

When this modal window appears, the buttons are not active, in order for the buttons to start working, you need to interact with scrollview, after that a modal view will jump (it will decrease by a few pixels) and the buttons will become active, I hope I explained it clearly) I also attach an example code from your project.

.partialSheet(presented: $showPartialSheet, backgroundColor: Color(UIColor.secondarySystemBackground)) {
     ChangeIcons()
}

struct ChangeIcons: View {
    var body: some View {
        ScrollView(.horizontal, showsIndicators: false) {
            HStack {
                VStack(alignment: .center) {
                    Button(action: foofunc) {
                        Image("infoApp")
                            .resizable()
                            .renderingMode(.original)
                            .cornerRadius(15)
                            .frame(width: 80, height: 80)
                            .overlay(
                                RoundedRectangle(cornerRadius: 15)
                                    .stroke(Color.red, lineWidth: 3)
                                    .frame(width: 90, height: 90)
                        )
                    }.frame(width: 95, height: 95)
                    Text("Стандартная")
                        .font(.system(size: 11, design: .rounded))
                        .bold()
                }
                VStack(alignment: .center) {
                    Button(action: fooFunc) {
                        Image("altIconApp")
                            .resizable()
                            .renderingMode(.original)
                            .cornerRadius(15)
                            .frame(width: 80, height: 80)
                            .overlay(
                                RoundedRectangle(cornerRadius: 15)
                                    .stroke(Color.red, lineWidth: 3)
                                    .frame(width: 90, height: 90)
                        )
                    }.frame(width: 95, height: 95)
                    Text("Автор иконки")
                        .font(.system(size: 11, design: .rounded))
                        .bold()
                }
            }.padding(.horizontal)
        }.onAppear(perform: fooFunc)

This video is taken from the builtin example

I put the partialSheet inside a List and saw that the partialSheet does not fit in the right position. Is there a way to fix it?

So I've noticed placing a picker in a partial sheet causes some weird issues.

1. Dragging on the picker triggers the drag gesture of the sheet. So when you try to drag on the picker the sheet moves a bit before the picker does its thing.
2. Related to 1, if you have a TextField AND a picker in the partial sheet things get really bumpy. If the keyboard is open and you drag the picker, the drag gesture of the sheet gets triggered (as mentioned above) which tells the keyboard to dismiss. SwiftUI can't seem to handle this all at once and crashes.

Crash message

The crash originates here and is triggered here

I like this library and would like to continue using it for my app so some guidance on this would be appreciated.

Ability to stack a sheet onto another sheet.
Ability to dismiss existing sheet and quickly call a replacement sheet in function form.

This would make it easy to define an automatic layout behavior, wherein the sheet would expand in increments to show more sections if they fit, and respond to scroll, naturally. Some tension between each section would give it a more natural transition, such as the spring interrupted animation wherein you implement drag interception of animation, but only start the animation after a certain magnitude of the current section is no longer visible. This would make a very nice automatic part to an automatic scrolling UI behavior on each field, wherein the user advances the form automatically and naturally as they complete each section.

Hey, nice work!
I noticed that the animation is only played when closing per tap on the background, not on drag-closing.
Here is a PR fixing it :-)

Or is this intended? Then I'll just use my fork

I try to add a TextField into partial sheet, but it does not update its @State var.
Example:

self.partialSheetManager.showPartialSheet {
  TextField("Enter your name", text: self.$newBoardName)
  Text("Hello, \(self.newBoardName)!") // won't update
}

If I tried to embed a view made up of a Navigation view and a form inside the Partialsheet, the PartialSheet is much larger than it needs to be.

I put the partialSheet inside a List and saw that the partialSheet does not fit in the right position. Is there a way to fix it?

If you use a partial sheet to open one view.. close it.. then open the sheet with another view, the sheet open animation starts from the height of the previous sheet on the first open call of the new view.
[ISSUE FIXED IN 2.1.3]

It is documented to run the onDismiss, but does not.

/// Close the Partial Sheet and run the onDismiss function if it has been previously specified

    public func closePartialSheet() {
        self.isPresented = false
    }

The onDismiss function is run when dragging to close as expected.

I added something like this and bound it to an action and now I get the onDismiss to fire.

public func dismissPartialSheet() {
        self.isPresented = false
        self.onDismiss?()
}

I am not sure if there was intent to have the closePartialSheet merely close the sheet (e.g. maybe a cancel-type scenario) without running the onDismiss function.

sheet don't work on devices with iOS 13.1 or 13.0
it shows only white screen

It there any way we can change the entire background color of the sheet, looks like it is always in white color. Would like to use it in dark mode.
Thank you so much!

I have looked at the library before, but have never used it. Now I've decided to use it and, as I understand, starting from 2.0, it's not possible to initialise PartialSheet using a binding, and is possible only using a user action (pressing a button and calling the sheet action there). If this is indeed so, I think it's a bit of a downgrade and is not in line with the SwiftUI approach.

I use global state for my navigation, so before, I could configure the state (in case of deep linking, for instance) and this way navigate to any of the views, including an opened sheet. Now it looks like I can't do that.

PartialSheet is awesome and your work on 2.0 has been terrific! Thank you for what you are doing!

I have a bug in my prototype app. I do not know if it is caused by PartialSheet. I'm not as familiar with Xcode as I would like to be, and so you may want to ask me for more information.

Here is the setup:

• I have a SwiftUI view called ViewA() that has a form. In that form is a view called MapVIew() that contains an MKMapView via UIViewRepresentable. MapView() has several params, one of which is a Bool for editing. MapView() within the form on ViewA() is not editable.
• When the user taps on the MapView() in the form on ViewA(), a NavigationLInk pushes a new view, ViewB(), that contains a new instance of MapView() with the MKMapView, but this time it is editable.
• In ViewB(), the user can center the user location, bring up a settings PartialSheet, and drop a pin by long-pressing on the MKMapView contained within MapView().
• Within the settings PartialSheet, the user can change the map type (Standard, Satellite, Hybrid) and drop a pin exactly on the user's current location.
• If the user taps on a dropped pin, detail about that pin is shown on another PartialSheet, including the reverse geocoded street address, the latitude, and the longitude. This PartialSheet also contains a button to remove the pin.
• Only 1 dropped pin is shown at a time on the map. If the user drops another pin at the user location or long-presses on another location in the MKMapView, any pin that already exists is removed.
• Both PartialSheets are closed by calling .closePartialSheet() on the PartialSheetManager environment object.
• The MapView() instance on ViewA() and the MapView() instance on ViewB() show the same MKMapView data, including user location and a dropped pin, if it exists. The only differences which MapView() is editable and the sizes of the MapView() instances are different in ViewA() vs. ViewB().

A description of the problem:

• As long as I stay on ViewB(), I can bring up the settings PartialSheet and drop pins on the user location as much as I would like. I can also drop as many pins as needed (one at a time) at other locations on the MKMapView and bring up the pin detail PartialSheet for each one without any problems.
• However, if I back out ViewB() to the parent ViewA() with the form, tap on the MapView() in the form to go back to ViewB(), and then either 1) bring up the settings PartialSheet, or 2) show pin detail by tapping on the pin, the app crashes with Thread 1: EXC_BREAKPOINT (code=1, subcode=0x1da55a12c).
• Clarification: The crash occurs only after a PartialSheet is opened and closed on ViewB(), returning to ViewA(), going back to ViewB() and opening a PartialSheet.
• In both crashes, the PartialSheet does not show before the crash.
• This crash did not occur when I was using v1.0.3 of PartialSheet. It only appeared after I started using v2.1. (That doesn't mean I did not create a problem in my code when converting it to accommodate PartialSheet changes from 1.0.3 to 2.1.)
• The code to bring up the settings PartialSheet and the pin detail PartialSheet are in two different files. The settings PartialSheet code is in ViewB() and the pin detail PartialSheet is in MapView().
• When I print stack traces for both crashes, it appears to be caused by the same code location in SwiftUI. (SwiftUI 0x00000001da5600f0 3652361F-29A7-3130-AB4A-72A5F7BB506B + 5628144) The stack traces are pasted below.

Would it be possible that PartialSheet has a common bug that causes both crashes? What other information do you need from me?

Thank you very much for your help.

Hello.
Please add possibility to remove the bottom empty space.

Xcode 12 canvas crashes as soon as PartialSheet is imported to view. Any idea how to fix this?

I have tried this in my app by replacing different working instances of .sheet with .partialSheet and none of them has worked. The results have either been a blank sheet or corruption of the presenting view. Nice idea but I suspect it needs broader testing.

I have NavigationView and on activation NavigationLink, handler bar appears

Hey, it would be totally awesome if you provide a license, otherwise it is illegal for others to use your code.

The license you choose is for sure up to you, but I would suggest to make it as easy as possible for people to use your code, use the Unlicense.
Otherwise, MIT is a popular choice.

Great swiftui element you developed there!

I'm struggling to get sheet running on a mixed setup and your documentation shows only the usage if app is configured with swiftUI form beginning.

can you show us how to use it if we don't have such a setup.

Thank you in advance!

It appears that the new addition of keyboard observers causes elements like a tab bar to shift above the keyboard in instances where the partial sheet is added to the TabView and a keyboard is presented at any time, sheet presented or not. I think I have a solution that works.

Instead of .padding(.bottom, self.offset) in the PartialSheetViewModifier on line 79, the negative offset should be added to iPhoneSheet() as such .offset(x: 0, y: -self.offset) on like 113.

if deviceType == .iphone {
    iPhoneSheet()
        .offset(x: 0, y: -self.offset)
        .edgesIgnoringSafeArea(.vertical)
}

From my testing this solution will prevent the whole content from receiving a padding when the keyboard presents.

I have the use case below :

• NavigationView with a NavigationLink (send the user to second view[page])
• the second view use .partialSheet
• the partialSheet view has a Textfield
  when the keyboard is opened , there is an issue as the image below :

Thanks for the amazing Swift package. It saved a lot of hours of work.

I would like to ask if it's possible to implement a functionality where, the partial sheet should have the max height equal to half the screen size (or height passed in configuration) on initial load and when swipe up, the height should change to full screen. I understand this should only be possible for contents which are of size more than half of screen.

Something like this gif. Where the partial screen takes full height when searching using a keyboard.

I wrote the following code.
However, NavigationLink doesn't work.
How do I use NavigationLink in PertialSheet?

import PartialSheet
import SwiftUI

struct ContentView: View {
    @EnvironmentObject private var partialSheetManager: PartialSheetManager
    var body: some View {
        NavigationView {
            Button(action: {
                self.partialSheetManager.showPartialSheet {
                    NavigationLink(destination: Text("destination view")) {
                        Text("navigation link")
                    }
                }
            }) {
                Text("show partial sheet")
            }
        }
        .navigationViewStyle(StackNavigationViewStyle())
        .addPartialSheet()
    }
}

There is this set on the sheet view:
.animation(self.dragState.isDragging ? nil : .interpolatingSpring(stiffness: 300.0, damping: 30.0, initialVelocity: 10.0)) which applies animation to the content of the sheet. In my case, I have views which are hidden and shown depending on the state in the sheet content and now they are automatically animated.

Per Apple's documentation on animation(_:): Use this modifier on leaf views rather than container views. The animation applies to all child views within this view; calling animation(_:) on a container view can lead to unbounded scope.

Basically, setting this on the the container (sheet view) is an anti-pattern. I think, explicit property animation should be used instead, this way no matter what the content is provided to the PartialSheet, it will not be affected.

if we place a TabVIew and add a partial sheet to it, then add some NavigationViews for tabs and go to inside of NavigationView child views if view uses ObservedObject for ViewModel when we open partial sheet all variables in ObservedObject of ViewModel was reset

I have content for SheetView inside a ScrollView. And under ScrollView there are few UI elements and one button. So when the view loaded the first time the button is not working. But after doing the scroll event the button starts working. Here is my code,

//Main ContentView
`var body: some View {

    HStack {
        Spacer()
        Button(action: {
            self.partialSheetManager.showPartialSheet({
                 print("normal sheet dismissed")
            }) {
                 SheetView()
            }
        }, label: {
            Text("Display the Partial Sheet")
        })
    }
}`

//SheetView

`struct SheetView: View {
var body: some View {
VStack {

        ScrollView {
            Text("Hello")
            
            Button(action: {
                print("Button is tapping")
            }) {
                Text("Tap Here")
            }
        }
    }
}

}`

Hello mate, firstly thanks for this repo :)

I want to use it with custom static heights.
For example y:200 and y:600 cases. Is there any way to do it ?

I made this custom modal but it's not working so well. This screenshots will help you to understand what I'm trying to do.

Thanks in advance :)

It would be nice to have a blur effect on the sheet as well, similar to the sheet on Apple Maps.

Any possible to using AnyTransiton to insert it into View Hierarchy when presented and remove it when not presented.
Now partialSheet view is just being hidden off of the screen instead of being removed.
Possible improvements may be like below:

if presented {
    PartialSheetContent.offset(offsetWhenPresented)
        .transition(anyTransitionMethod).animation(anyAnimation)
} 
else {
    EmptyView()
}
