init() in SwiftUI for State var is a bit tricky: https://www.hackingwithswift.com/forums/swiftui/why-no-setting-of-intial-state/2021 Something like this should work:     @Binding var playingId: Int?     @State var player: AVPlayer!     init(playingId: Binding<Int?>, player: AVPlayer) {         _player = State(initialValue: player)         self._playingId = playingId }

If you illustrate behaviour by showing interactions, you do not decompile, you simply execute. So there should not be decompilation legal issue. Take care to fully follow open software rules (you may have to publish the relevant parts of your code in open source). I would also advise to be very clear when you submit to Appstore, by explaining the situation in the comments to reviewer.

There may be an identifier missing . Replace List(m_watch_list_view_model.m_watch_list_model) { watch_list_model in with List(m_watch_list_view_model.m_watch_list_model, id: \.id) { watch_list_model in Note: the use of underscore in name is not Switish at all. Remove them and replace by camelCase. For instance m_watch_list_view_model should become mWatchListViewModel furthermore, the starting m has not clear meaning.  So you could replace with watchListViewModel

Thanks for the feedback. Don’t forget to close your thread.

No direct answer to the question. But take care on rules for review: there are strict limits to adding executable code to an app. 2.5.2 Apps should be self-contained in their bundles, and may not read or write data outside the designated container area, nor may they download, install, or execute code which introduces or changes features or functionality of the app, including other apps. Educational apps designed to teach, develop, or allow students to test executable code may, in limited circumstances, download code provided that such code is not used for other purposes. Such apps must make the source code provided by the app completely viewable and editable by the user.

1.       var xvalues: [CGFloat] = [] 2.       var yvalues: [CGFloat] = [] 3.       if (observation1.count) == 5{ 4.         for n in observation1 { 5.           xvalues.append(n.x) 6.           yvalues.append(n.y) 7.         } 8.         filter1 = convolve(xvalues, sgfilterwindow5_order2) 9.         filter2 = convolve(yvalues, sgfilterwindow5_order2) It seems you miss a closing curly bracket before line 8. Use map function: if (observation1.count) == 5 { xvalues = observation1.map {$0.x } yvalues = observation1.map {$0.y } }

@szymczyk plus If it still doesn't work, do a clean build folder and possibly restart Xcode.

Could you check what you get for the 11 label if you select Aug 12 ?

Here is what I get with a default (blue) background: Problem is that today is now blu, not white. But could not find a way to change the color in selection.

Are you using third party frameworks ? With which version of Xcode was the project created ? Have you looked at the issues Navigator (left pane in Xcode) to see if you have warnings to update to new settings ? If so, update, then clean build folder and restart Xcode. Try again to build again. If you still have the problem, create a phony new project, and try to build. What do you get ?

I have the same error in a new project Is it a Swift/UIKit project (not SwiftUI) ? Is it a new project without framework, just create and run ? If so, problem likely comes from your config. May try to load XCode13ß5, just available.

When you post code, please format code in a more readable way and use code formatter, such as: struct NavigationIndicator: UIViewControllerRepresentable { typealias UIViewControllerType = ARVieww func makeUIViewController(context: Context) -> ARVieww { return ARVieww() } func updateUIViewController(_ uiViewController: NavigationIndicator.UIViewControllerType, context: UIViewControllerRepresentableContext) { } } Where exactly do you get the crash ?

Yes, it may be a question of how fast you lift the finger. See discussion here: https://stackoverflow.com/questions/10325776/touchescancelled-is-called-instead-of-touchesended The best is probably to call the same code for touchesEnded and touchesCancelled.

I am confused on which path to head down : SwiftUI or Appkit. I (personal opinion) recommend to stay with Appkit. Because of maturity of SwiftUI and because it introduces another layer that make things even more complex. Here a a good tutorial series to start: h t t p s : / / w w w .raywenderlich.com/731-macos-development-for-beginners-part-1 h t t p s : / / w w w .raywenderlich.com/730-macos-development-for-beginners-part-2 h t t p s : / / w w w .raywenderlich.com/729-macos-development-for-beginners-part-3 And this, it's an old document (2013) but very detailed: https://developer.apple.com/library/archive/referencelibrary/GettingStarted/RoadMapOSX/chapters/01_Introduction.html

That's not where the error is. It is just the place where debugger returns after crash. You have to find where is the crash, for instance by adding some print statements at the place of last action before crash.
