仅在物理设备上“尝试添加已经有父节点的 SKNode”，代码中没有错误，在模拟器上工作正常

Question

Running my app on a simulator works fine, however, running it on a physical device gives this error. I understand what this error means but my code seems fine, in fact, if I get rid of the trouble code (in this case the camera) another part of the code receives the same error.

I am targeting iOS 10.3 and running on a iOS 10.3 device, it works fine on iOS 11.0 simulator

code:

class GameScene: SKScene {

    var lastUpdateTime: TimeInterval = 0
    let pigeonCam: SKCameraNode = SKCameraNode()
    let pigeon: Pigeon = Pigeon()
    var dt = 0.0
    let ground: SKSpriteNode = SKSpriteNode(imageNamed: "Road")//crashes if camera and pigeon do not exist

    override func sceneDidLoad() {
        addChild(pigeonCam)//crashes
        camera = pigeonCam
        addChild(pigeon.pigeon)//crashes if camera code does not exist
        createGround()
        scene?.scaleMode = .resizeFill
    }

I have tried restarting the device unit/reinstalling the app but it appears to not help, aside from a few lines of code in 'pigeon' this is the entirety of my code in the app. I'm sure it's got to do with deployment settings or something of the like but I'm stumped

Answer 1

I have done some research, and it is quite possible the reason this is happening is because I don't have a provisioning profile
