This has been tested in Xcode 15.5.1 on a Macbook Pro Mid 2014 running macOS Big Sur 11.5.2 (20G95), on simulators running iOS 12.1, 14.5, and iPhone Xs running iOS 14.8.

I have the same problem when trying to use something from iOS 15 only, using if #available(iOS 15.0, *) {. Crashes on iOS 14 with "dyld: Symbol not found". Have you found a solution to this problem?

Have you found any solution to this problem? I get the same crash with Xcode 13, trying to use something from iOS 15 and it crashes on iOS 14.

Where you able to find a solution? I get the same crash using if #available(iOS 15.0, *) { on Xcode 13.

Thanks a lot @OOPer. It works as intended. One more related question. To track the paused state inside of the SpriteKit scene, I guess the best option would be to call a method on the scene, maybe in the onChange(of:perform:) modifier? var body: some View {     ZStack {       SpriteView(scene: scene, isPaused: showingLevelChooser)         .ignoresSafeArea()       VStack {         Button("Level Chooser") {           showingLevelChooser.toggle()         }         Spacer()       }     }     .sheet(isPresented: $showingLevelChooser) {       VStack {         Button("Cancel") {           showingLevelChooser.toggle()         }         Text("Level Chooser")       }       .background(BackgroundClearView())     } //↓     .onChange(of: showingLevelChooser) { value in       scene.isPaused(value)     }   }

Any update on this warning?

The solution is to use an id on the GameScene and send it to the SpriteView with the .id() modifier, to force SwiftUI to create a new SpriteView. class GameScene: SKScene, ObservableObject { var id = UUID() } SpriteView(scene: scene, isPaused: paused).id(scene.id) This question was answered on SO: https://stackoverflow.com/questions/69610165/spriteview-doesnt-pause-scene-on-state-change/69610906#69610906 by @jnpdx.

Yes, what I meant is being able to run/test apps on devices running iOS 15.4+, or on the simulator running those versions. Basically you won't be able to use iOS 15.4+ SDKs at all while developing. This is definitely not good. A 2014 Macbook Pro is totally capable of running Monterey. Even more so that the 2014 Mac Mini is still supported by Apple to update to Monterey. A decision that is really hard to understand... Thanks for your reply.

Same problem here. Has anyone found any workarounds to this issue?

It looks like a bug or a change that was introduced in the framework, that is contrary to what the docs say. Consider filling a bug report with Apple https://feedbackassistant.apple.com/

Looks like there is more to SKView.showsFields. When showsFields is true, if you have an SKFieldNode.customField({}) in the scene, the custom block is called for what appears to be physics bodies to the far top right, with different positions, zero velocity, 1.0 mass, 0.0 charge. Same, this can be easily replicated using the Game Playground, by adding an SKFieldNode.customField({}) with a block that prints out the arguments. If SKView.showsFields is false, the block is not called, as it should be. Feedback report has been updated but there's no update on it.
