I honestly thought this repo was just for iOS and then found out it supports macOS as well. This is great since I'm going to be using it for Mac apps.

I believe it would be helpful to mention this in the readme as well as the minimum version of macOS needed, which seems to be 10.12.

And thanks for supporting both iOS and macOS, it's a nice change to see!

• (nullable NSData *)cachedPurchaserInfoDataForAppUserID:(NSString *)appUserID
  {
  if(appUserID) { // Added this...
  return [self.userDefaults dataForKey:[self purchaserInfoUserDefaultCacheKeyForAppUserID:appUserID]];
  } // Added this...
  return nil; // Added this...
  }

I would like to hand to my users promo code that unlocks consumables IAP (on iOS) as detailed by Apple here: https://help.apple.com/app-store-connect/#/dev50869de4a

However, I do not see any "listeners" on RCPurchasesDelegate.

How can I handle this case?

I just updated my copy of Purchases to the latest version, and got hit with a bunch of compiler errors about missing methods or missing parameters.

Next time you add parameters, leave the old method in place but mark it as deprecated, and add the hint to use a different on instead.

Instead of removing methods, remove their implementations, and then mark the method in the header as deprecated, and point to the new method.

This helps make upgrading from release to release much easier for users.

I have ensured my products are correctly configured in ASC. They are in the "Ready to Submit" state. I can use these same product identifiers to successfully pull products via SwiftyStoreKit and through Apple's API. This leads me to assume that the problem is with my configuration in RevenueCat. But I've gone through the documentation multiple times now over several days and I can't figure out where the problem is. @jeiting I know you diagnose these problems a lot and I've read your blogs. I'm out of things to check and just desperate for some suggestions. Thanks.

Hi, I have the error with version 4.0 when running it with the latest Xcode beta.

Hi,

I am getting this error immediately after running pod install.

purchases-ios-2.3.0/Examples/SwiftExample/Target Support Files/Pods-SwiftExample/Pods-SwiftExample.debug.xcconfig: unable to open file (in target "SwiftExample" in project "SwiftExample") (in target 'SwiftExample')

podfile content is

platform :ios, '12.0'

use_frameworks!

target 'SwiftExample' do

 # Pods for SwiftExample
 pod 'Purchases', :path => '../../'

end

I changed platform version and added use_frameworks

I know it is pod framework related but i tried all solutions on stackoverflow and Cocoapods GitHub thread. Nothing worked.

what could be the issue?

Thanks
Ashish

Here is some sample client code that demonstrates the issue

    for purchasedProductIdentifier in purchaserInfo.allPurchasedProductIdentifiers {
        
        print ("ID: \(purchasedProductIdentifier)")
        print("Start Date:  \(String(describing: purchaserInfo.purchaseDate(forProductIdentifier: purchasedProductIdentifier)))")
        print("End Date:  \(String(describing: purchaserInfo.expirationDate(forProductIdentifier: purchasedProductIdentifier)))")
    }

For renewing products, the purchase date is always nil.

Hi,

Could you please add Swift 5 support.

Thank you.

Hi,

I'm trying to upload a beta build of my app, which I just integrated with RevenueCat, to App Store Connect. I'm using Carthage to build the 3.0.0 version of RevenueCat.

I get this error on submission:

App Store Connect Operation Error
Unsupported Architectures. The executable for MyApp.app/Frameworks/Purchases.framework contains unsupported architectures '[x86_64, i386]'.

App Store Connect Operation Error
Invalid Segment Alignment. The app binary at 'MyApp.app/Frameworks/Purchases.framework/Purchases' does not have proper segment alignment. Try rebuilding the app with the latest Xcode version.

App Store Connect Operation Error
The binary is invalid. The encryption info in the LC_ENCRYPTION_INFO load command is either missing or invalid, or the binary is already encrypted. This binary does not seem to have been built with Apple's linker.

I'm using Xcode 11.2.1, and I believe my command-line build environment is set up properly:

$ xcode-select -p
/Applications/Xcode.app/Contents/Developer

I noticed that you recommend using the --no-use-binaries flag in Carthage, and I've tried both with and without that flag. I get the error either way.

carthage build --platform ios --configuration Release --no-use-binaries
carthage build --platform ios --configuration Release

I'm wondering whether the second and third error might be because of the first one. Do you know what I can do to prevent RevenueCat from building x86 targets when making iOS-only builds using Carthage?

On an Apple TV 4K, running on the device (no simulator), everything works fine as long as the TV is on. As soon as I turn the TV off, I see:

12:21:59-0700 MyApp[] [Purchases] - INFO: Subscriber attributes synced successfully

(I've removed the date from the beginning of each line to shorten the length). It does this about every 5 seconds until the TV is turned back on whereupon it returns to normal.

This line will call with empty array:
https://github.com/RevenueCat/purchases-ios/blob/master/Purchases/RCStoreKitRequestFetcher.m#L172

And it will cause crash here
https://github.com/RevenueCat/purchases-ios/blob/3.0.0-beta/Purchases/Public/RCPurchases.m#L955

I'm not exactly sure when/how this can cause undesired behavior, but it should be a single equals:

Hello,

Let's say a user has an active subscription to product X and redeems an offer for the same product. The operation is successful according to Apple, which is indicated by "You're all set" popup. However, we receive transaction with state .failed along with some generic error in -makePurchase:withDiscount:completionBlock: callback in this case. Also no changes in RevenueCat dashboard nor in decoded receipt are observed immediately after that.

Is it intended behaviour, a bug in RevenueCat or some glitch in Apple sandbox?

Steps to reproduce:

• Open the Purchases.xcodeproj project in Xcode 11.4
• Choose an iOS Simulator as target
• Perform a static analysis with Product > Analyze

Result:
You see 3 warnings "nil passed to a callee that requires a non-null parameter":

1. purchases-ios/Purchases/SubscriberAttributes/RCSubscriberAttributesManager.m:81:5: warning: nil passed to a callee that requires a non-null 2nd parameter
   [self storeAttributeLocallyIfNeededWithKey:key value:value appUserID:appUserID];

2. purchases-ios/Purchases/Public/RCPurchases.m:177:26: warning: nil passed to a callee that requires a non-null 2nd parameter
   RCBackend *backend = [[RCBackend alloc] initWithAPIKey:APIKey platformFlavor:platformFlavor];

3. purchases-ios/Purchases/Public/RCPurchases.m:874:9: warning: nil passed to a callee that requires a non-null 1st parameter
   [self markAttributesAsSyncedIfNeeded:subscriberAttributes appUserID:self.appUserID error:error];

It appears that the methods where nil is passed as parameter can perfectly handled the nil parameter. So I would assume that the keyword nullable is missing from the method prototype.

I'd love to see combine added to this library. https://developer.apple.com/documentation/combine

All of the networking code in my app uses combine except for this library. This would also be helpful in composing these api calls. This could be done just adding swift extensions to the current library.

Hey!

I use purchases in an iPadOS app and ever since Xcode 11.4 Beta 1 (and persisting through to Beta 2), I haven't been able to compile my app.

Upon compiling, I get 7 errors

The periodType in active entitlements is null. This is during sandbox testing with the latest version 3.2.2. If this is due to the sandbox, is there a way we can test to ensure it works in production?

When do you release swift version here ?

Hi !
How can I determine what exactly subscription is active now, if when I get all offers using Purchases.shared.offerings I get all identifiers like:

• 0 : "$rc_monthly"
• 1 : "$rc_annual"

and when I'm fetching purchaseInfo using Purchases.shared.purchaserInfo, the identifiers are the ones associated with my products, like:

• 0 :com.product.subscription.month
• 1 : com.product.subscription.year

thanks

Xcode 11 comes with swift package manager, a lot easier than dealing with cocoapods or carthage, all of our other packages are on SPM, would love to see this one be there as well!

Hello, I'm using the same PayWall in this repo as a payment screen. I have a non-renewing product. In my previous version, PayWall was directly presented to the user after launching the app. Now in this rejected version, I only moved the Paywall from the app start to the behind of 'download' button. Now the user transforms the image and performs the basic function of the app and then PayWall shown if the user wants to download the image.
What do you guys advise me to handle this rejection?

Guideline 3.1.1 - Business - Payments - In-App Purchase

We found that your app includes a feature to restore previously purchased in-app purchase products by entering the user's Apple ID and password. However, non-renewable subscriptions in-app purchases cannot be restored in this manner.

To resolve this issue, please revise your binary to implement your own restore mechanism, if you would like users to be able to restore non-renewable subscriptions in-app purchase products.

More information on in-app purchase product types is available in App Store Connect Help.

Guideline 3.1.2 - Business - Payments - Subscriptions

Your app offers a content subscription but does not have a mechanism in place to support the requirement that the subscription content be available to the user on all of their iOS devices.

Next Steps

To resolve this issue, please modify your app to include an optional user registration feature to deliver subscription content to all of the user's iOS devices. Such user registration must be made optional, not required. We also recommend indicating that registering is required to access the subscription content from their other iOS devices - and providing a way to register later, if users wish to have access to this content at a future time.

Hi,

I have when a problem when I need re-init Purchases class with a different userId during the same app session. Dealloc is not being called so all the listeners are still active for old user too(all calls are multiplied by number of pre-used users).
Workaround for now - manually set delegate to nil.

I'm getting a bunch of "missing nullability annotation" warnings in RCPurchaserInfo+Protected.h.

I'm not sure what the annotations should be, or I'd probably do it myself. I like my projects to build cleanly without warnings.

I have a crash occurring here since appUserID is nil for some reason...

RCDeviceCache.m (Line 88)

• (NSString *)purchaserInfoUserDefaultCacheKeyForAppUserID:(NSString *)appUserID {
  return [RCPurchaserInfoAppUserDefaultsKeyBase stringByAppendingString:appUserID];
  }

Should at least protect from nullable input like this.

• (NSString *)purchaserInfoUserDefaultCacheKeyForAppUserID:(NSString *)appUserID {
  if(appUserID == nil) { return nil; }
  return [RCPurchaserInfoAppUserDefaultsKeyBase stringByAppendingString:appUserID];
  }

Or is there a reason why appUserID would be nil?

Hi, i recently updated my Purchases pod version 2.6 to 3.0.4. I also changed getting offerings method to this :

Purchases.shared.offerings { (offerings, error) in
            if let packages = offerings?.current?.availablePackages {
                // Display packages for sale
            }
}

but i couldn't be able to get current offerings.
i tried to delete derived data , deintegrating pods and installing again, deleting build folders, but no conclusion.
the error is :

Printing description of offering:
expression produced error: error: /var/folders/4g/w58ds9mx2l77zy4fzbd97jyw0000gn/T/expr11-5be3e6..swift:1:90: error: 'Purchases' is not a member type of 'Purchases'
Swift._DebuggerSupport.stringForPrintObject(Swift.UnsafePointer<Swift.Optional<Purchases.Purchases.Offerings>>(bitPattern: 0x1154b4450)!.pointee)
                                                                               ~~~~~~~~~ ^

Since RevenueCat does not fully support non-renewing subscriptions (restoration across devices, storing expiration dates, etc) I am working around this by storing the information in Firebase. However, I need to tie together purchases made in one device to another device of the same user for restoration.

Initially I tried to use RCPurchases.appUserID to do so but learned that they are unique to the device, not the appleID user, when using anonymous auth.

My app has no need for login/authorization beyond purchasing products and my users have spoken loudly they don't want a monthly subscription to the app. So non-renewing products are critical.

One solution I have is to expose the master user ID in the RevenueCat backend in RCPurchases or in RCPurchaserInfo. It is my understanding that this is the primary key for joining the list of device userAppIDs. This would give me a 1:1 relationship to the appleID I need to restore non-renewing transactions from Firebase. I think this would be a reasonable stopgap until RevenueCat fully supports non-renewing products.

I am open to other ideas to handle this too, this is simply the best one I thought of. In the end, solving the restoration and storing of supplemental information is the primary goal ahead of RevenueCat fully supporting non-renewing products. Ideally, if this could be exposed by Dec 15, 2018 that would align best with the 'season' picking up for my customers.

The following method is currently unused, although it would be handy if it was available through the public header. Without it, there is no way to explicitly trigger a network fetch which may be desirable, particularly from extensions where the applicationDidBecomeActive: handler does not get called (and adding NSExtensionHostDidBecomeActive would not be sufficient).

If made available, it should probably be renamed to updatePurchaserInfo or something else that clearly conveys a network fetch is going to happen (fetch?).

Annotate 'RCPaymentModeFromSKProductDiscountPaymentMode' with an availability attribute to silence this warning

iOS 12 issue.

RCBackend.h:33
RCPaymentMode RCPaymentModeFromSKProductDiscountPaymentMode(SKProductDiscountPaymentMode paymentMode);

should be

API_AVAILABLE(ios(11.2)) RCPaymentMode RCPaymentModeFromSKProductDiscountPaymentMode(SKProductDiscountPaymentMode paymentMode);

RCBackend.m
RCPaymentMode RCPaymentModeFromSKProductDiscountPaymentMode(SKProductDiscountPaymentMode paymentMode)

should be

API_AVAILABLE(ios(11.2)) RCPaymentMode RCPaymentModeFromSKProductDiscountPaymentMode(SKProductDiscountPaymentMode paymentMode)

I have enough bugs that I produce myself, so would be awesome to not have to deal with yours as well ;)

I am developing a Mac App and seem to be getting a return of nil entitlemnts after implementing an instance of RCPurchases setting the delegate and calling the completion handler purchases?.entitlements({ (entitlements) in . Am I missing something. Please can you help.

please add swiftUI example

Running Carthage update produces the below, but nothing is actually downloaded:

*** Downloading purchases-ios.framework binary at "1.0.4"

Can you please add to your SDK original property from apple receipt validation original_transaction_id ?

It is really necessary, because having all users marked as anonymous, it seems to be the only persistent value witch can be used as userID

thanks

It would be great if we could add this as a dependency just using git submodules if we are not using Carthage or Cocoapods.

Hi Guys

I have been using revenue cat on my MacOS app Shepherd for a couple of weeks now. Things were up and running. After updating the app with a bug fix (not related to purchases), I received this message from app rejecting the app.

"Your app enables the purchase of content, services, or functionality by means other than the in-app purchase (IAP) API.

We noticed that your app or its metadata provides access to external mechanisms for purchases or subscriptions to be used in the app, which does not comply with the App Store Review Guidelines."

Is this related to revenue cat's version not been updated to the latest version in line with Apples IAP API?
Have you encountered this before?
Is this perhaps a classic app store review that is misunderstood?

Your help will be appreciated.

I am currently using revenue cat for MacOS Version 2.3.

I use Purchases (v 1.2.0) in my project. I can see the Purchases library sends the receipt data even if user cancels the subscription restore. In this case RevenueCat backend returns error:

("Error Domain=RCBackendErrorDomain Code=0 "The receipt is not valid." UserInfo= { NSLocalizedDescription=The receipt is not valid. }")

and sends this error to delegate method. How can I distinguish between the case when user cancels restore subscription and the "real" backend error happens? Thanks!

Currently RCSetShowDebugLogs(YES) will cause logging to go to NSLog. We (and presumably a lot of other people) have our own logger, and we would prefer to have logging routed through it.

The MVP for this is something like RCSetLoggingFunction(void *fn);

Hi,
I am just integrating RevenueCat for subscriptions and when I try to do a purhcase, activeProduct is nil. According to the documentation:

The active product, this will be null if the product is not available, usually because it has not been approved for sale

This is correct, my product in iTunesConnect is still not Ready for Sale, but how can I test this? I want to call self.purchases.makePurchase(product).

Am I missing anything? Did I understood it wrong?

I use Xcode 10.0 and an iPhone X with iOS 12.

Thank you

As soon as configure function is called library is making 2 network calls. This is a new logic and wasn't there before. Is it a bug or there is reasoning behind this decision?

When I call restoreTransactions I'm prompted for my app store password. If I tap cancel, I would expect an error or other indication of cancellation, but my completion is called with success.

I would like to know if the operation is cancelled so that I can know whether to show a "purchases restored" alert.

Have an option in the SDK to delete / stop the current active instance of Purchases.

It can be useful in cases where the user signs out and you don't want to use an anonymous app user ID.

I find myself copying and pasting the same generic wrapper around RevenueCat into every app I make.

The issue is the purchasing is all handled through the delegate methods so I have to have a class that stores the completion block like so:

//MARK:- My Purchase Code
    
    public fileprivate(set) var analyticsProMonthly: SKProduct?
    fileprivate var completion: ((Bool?, Error?) -> ())?
    
    public func purchaseAnalyticsProMonthly(_ completion: @escaping (Bool?, Error?) -> ()) {
        self.completion = completion
        
        if let analyticsProMonthly = self.analyticsProMonthly {
            self.purchases.makePurchase(analyticsProMonthly)
        } else {
            purchases.products(withIdentifiers: [analyticsProMonthly2Identifier]) { (products) in
                if let product =  products.first {
                    self.purchases.makePurchase(product)
                } else {
                    completion(false, "couldn't get products" as? Error)
                }
            }
        }
    }
    
    //MARK:- RCPurchasesDelegate
    
    public func restoreTransactions(_ completion: @escaping (Bool?, Error?) -> ()) {
        self.completion = completion
        
        purchases.restoreTransactionsForAppStoreAccount()
    }
    
    public func purchases(_ purchases: RCPurchases, restoredTransactionsWith purchaserInfo: RCPurchaserInfo) {
        if let latestExpirationDate = purchaserInfo.latestExpirationDate {

        }

        self.completion = nil
    }
    
    public func purchases(_ purchases: RCPurchases, failedToRestoreTransactionsWithError error: Error) {

            self.latestExpirationDate = latestExpirationDate
            completion?(true, nil)
        }
        
        self.completion = nil
        self.activeSubscriptions = purchaserInfo.activeSubscriptions
    }
}

I really wish that it looked liked this:

public func purchaseProduct(productID: String, completion: (Bool, Error?) -> ()) {

}

And then a simple way of checking if the user is susbcribed. I think most users only have 1 tier and don't event have to check for various different products. Just a simple question, is the user subscribed or not?

purchases.isSubcribed(productID: String? = nil) -> Bool 

It's gotten to the point where I'm writing a development cocoapod for wrapping Purchases

Getting the following error when running the swift example app:

ld: warning: directory not found for option '-L/Users/Damian/Library/Developer/Xcode/DerivedData/SwiftExample-ezbgahlnwhanmghczzjmgcifqczs/Build/Products/Debug-iphoneos/Purchases'
ld: library not found for -lPurchases
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Hi, super excited to have found this potential IAP solution! But straightaway I'm getting an error:

Purchases.shared.offerings { (offerings, error) in
            if let packages = offerings?.current?.availablePackages {
                // Display packages for sale
            }
        }

The error:

expression produced error: error: /var/folders/9m/qr_cnwq903n_f_xf0nbgcf140000gn/T/expr9-ab7010..swift:1:90: error: 'Purchases' is not a member type of 'Purchases'
Swift._DebuggerSupport.stringForPrintObject(Swift.UnsafePointer<Swift.Optional<Purchases.Purchases.Offerings>>(bitPattern: 0x10be7d6e0)!.pointee)

Edit: Seems I get this error upon any attempt at using the API:

Purchases.shared.purchaserInfo { (purchaserInfo, error) in
            // access latest purchaserInfo
        }

Hi,

I'm trying to migrate to the new offerings system in a Swift project that has struct Package. It obviously conflicts with RCPackage, which is defined as Package for Swift. I installed RevenueCat via Cocoapods.

I tried to use Purchases.Package instead, but Xcode gives me the following error: 'Package' is not a member type of 'Purchases'.

I'm not sure if this is an issue of RevenueCat or Swift, however I wanted to give you a heads up. I created a sample project that demonstrates the issue.

Thanks.

ConflictingProject.zip

Everything was working well until I opened the project today. Looks like it's running 3.0.3 now.

I am running v3.2.2 on my iOS and WatchOS targets with the same appUserID value. After making a sandbox subscription purchase on iOS, the purchaserInfo on iOS returns the correct entitlement with "isActive" true. However on WatchOS, it returns that same entitlement with "isActive" false.

Oddly enough, WatchOS does list the expirationDate as a time in the future, indicating it is an active entitlement. Any suggestions for a work around on this? I'm thinking of using the expirationDate value for WatchOS purchase validation only.

The link to the "New Features" Trello board is broken.

I'm assuming this has either been removed or made private. Either way it should probably be removed from the docs.
