As of now, this app does not persist the data all my tasks are deleted as soon as the app closes. It would be great if my list is persisted and available to me everytime I open the application.

Describe the solution you'd like
This can be solved by the use of coreData.

Additional context
FetchedResultsController shall be used to load/store/delete/edit the data as it can be seamlessly integrated with the tableview.

I realy love the idea of your app. By showing completed task and uncompeletd task seprately. User can swip right to mark a task as done, but what if tehy did it by mistake?. The user may wants to mark the task as uncompleted, but there's no way to do it on history tab. It seems all I can do at hisgtory tab is just deleting task which is marked as done.
I widsh there is a mark as uncompeletd button to show up when user slid task swipe in history tab just like Tasks tab.

3. While searching if search results are not found then also we should display "No search results found" or something descriptive rather than blank screen.

Solution

1. A simple label which will be displayed in case no task is present in our core data.
2. Ternary operator which will hide and show filter option based on tasks count.
3. A simple label which will be displayed only in case no results are found.

Describe the bug
When trying to clone this repo on windows, I've came across an error

error: invalid path '.github/pull_request_template.md.'
fatal: unable to checkout working tree
warning: Clone succeeded, but checkout failed.
You can inspect what was checked out with 'git status'
and retry with 'git restore --source=HEAD :/

To Reproduce

1. Be on a Windows machine
2. Fork the repo
3. git clone %repo%

Expected behavior
The repository should be cloned

Solution
Obviously the issue lies on the .github/pull_request_template.md. file so if that file is removed, it should work fine. Otherwise, another possible alternative would be:

1. git init ToDo-iOS && cd ToDo-iOS
2. git config core.protectNTFS false
3. git remote add %repository_url%
4. git fetch
5. git checkout origin/master

I think your app may have tried to show the title of the Task, subtitle of the task, and image attached to it when the user clicks the button next to the task title. But on the history tab tapping the button doesn't direct to the new View as it does on the Task tab. Could you check this?

To Reproduce

1. Create a new task at Tasks Tab
2. Mark the task as completed by swiping it left
3. Go to History Tab and click the button next to the task title
4. Clicking the button doesn't direct to the new View as it does on the Task tab

Tested on

• Device: [iPhone 11 Pro]
• iOS: [14.1]
• Xcode [12.1]

Description
When launching the app for the first time, and no task is added yet, we see filter option in the navigation bar. Just a suggestion. It should only be displayed when any task is present. Else it should be hidden.

Solution
Ternary operator which will hide and show filter option based on tasks count.

Describe the bug
No image for task in tab bar.

Expected behavior
An image for task should be there.

Testing (please complete the following information):

• Device: iPhone7
• iOS: 13.3
• Xcode 11.3.1

I created a task on the tasks tab and swiped the task left. But that task didn't mark as completed nor doesn't appear on the History tab. (The text on the History tab said If the user swipe left the task then it will appear on the History tab and marked as completed)

Testing

• Device: [ iPhone 12 simulator]
• iOS: [14.0]

It would be great if the app had an onboarding screen like most application made by apple have.

Describe the solution you'd like

Is your feature request related to a problem? Please describe.
Tasks are stored and we don't have any indication for their priority. So cannot filter high priority tasks.

Describe the solution you'd like
High/Medium/Low priorities to be added for tasks. This need to be display to the right of the task name as a tag, just like the labels we see for different issues.
