I collect a lot of crash logs seem like this, but it seems that users are not affected by these crashes.
How it happened? I find a clue about this,
libAXSpeechManager.dylib			 0x6e31adbc -[AXSpeechThread main] + 368 (AXSpeechThread.m:50)
All crashes has Text to Speech function. my related code:
func speak(_ announcement: String,preDelay:TimeInterval = 0, endDelay:TimeInterval = 0,lan:String = "", rate:Float = AVSpeechUtteranceDefaultSpeechRate,didFinish:((_ str:String)->Void)? = nil) {
DispatchQueue.global(qos: .background).async {
let utterance = AVSpeechUtterance(string: announcement.lowercased())
utterance.volume = 2.0
if(lan.count > 0){
utterance.voice = AVSpeechSynthesisVoice(language:lan)
}
utterance.preUtteranceDelay = preDelay
utterance.postUtteranceDelay = endDelay
utterance.rate = rate
if let callback = didFinish {
self.synth.speakUtterance(utterance){
synth,utt in
callback("\(utt.speechString)")
}
} else {
self.synth.speak(utterance)
}
}
}
AVSpeechSynthesizer in watchOS seems easy to cause bugs.
Any suggest ? Thank you for help.

There are many crash logs collected when fire a local custom notification on watchOS.
But everything works fine in both real device and simulator tests.
Any suggestion thanks.

Problem:
SwiftUI render wrong size on old device like Apple Watch Series 4.
The height was be cut, not well render as series 6 or simulator.
Check the screenshots.
BTW:
But it works well both on watch series 6 real device or simulator.
Reproduce：
Download “Build a Workout App for Apple Watch”, run the code on a real device of watch series 4
https://developer.apple.com/videos/play/wwdc2021/10009/
On Watch4-44 mm (first line be clip)
On Simulator or watch 6.
I tried this:
https://developer.apple.com/documentation/activitykit/displaying-live-data-on-the-lock-screen-with-live-activities
I am building a workout app, the app can run in background , and I want to update the Live Activity realtime(once a second ) , so users can see the workout progress in realtime.
But as I test, when app in foreground the activity widget refreshed perfectly. But when the app goes to the background, it is not refreshed.
Now I am using iOS 16 beta 6, I can get buttonA/buttonB is pressed event. but cannot get accelerator motion data info.
//work
buttonA?.valueChangedHandler = {(_ button: GCControllerButtonInput, _ value: Float, _ pressed: Bool) -> Void in
print(">>> ButtonA tapped")
}
//work
buttonB?.valueChangedHandler = {(_ button: GCControllerButtonInput, _ value: Float, _ pressed: Bool) -> Void in
print(">>> ButtonB tapped")
}
// this is not works
gameController.motion?.valueChangedHandler = { (motion: GCMotion)->() in
print(">>>> motion data \(motion.acceleration.x) \(motion.acceleration.y) \(motion.acceleration.z)")
if let delegate = self.motionDelegate {
delegate.motionUpdate(motion: motion)
}
}
Is there any plan to support this?

I made a ball drop animation on the ARSCNView, then after 1 second, then deleted the ball and re-added it to the original position on the view, but this occasionally crashes.
something like this:
private func dropBall(){
// do ball dropping animation
let randomX = Float.random(in: -2...2) * 0.001
let randomY = Float.random(in: 3...10) * 0.001
ballNode?.physicsBody = SCNPhysicsBody(type: .dynamic, shape: nil)
ballNode?.physicsBody?.mass = 0.005
let position = SCNVector3(x: 0.05, y: 0.05, z: 0.05)
let force = SCNVector3(x: randomX, y: randomY , z: 0)
ballNode?.physicsBody?.applyForce(force, at: position, asImpulse: true)
let tv = SCNVector4(x: -0.2 + Float(0.4 * randomCGFloat()), y: 0 , z: 0.2, w: 0)
ballNode?.physicsBody?.applyTorque(tv, asImpulse: true)
//remove the ball
DispatchQueue.main.asyncAfter(deadline: .now() + 1){
self.ballNode?.physicsBody = nil
self.ballNode?.removeFromParentNode()
self.ballNode = nil
// add ball again
let ballNode = SCNReferenceNode(named: "myscn.scn")
contentNode?.addChildNode(ballNode)
self.ballNode = ballNode
}
}

How to fix this? This will only crash by chance and is not too easy to reproduce, is there a problem with me deleting this node in this way?
I want to implement a vertical scroll page like system workout app.
Now I can get a similar effect with this:
TabView {
page1
.rotationEffect(.degrees(90))
page2
.rotationEffect(.degrees(90))
}.tabViewStyle(.page(indexDisplayMode: .automatic))
.rotationEffect(.degrees(-90))
But not good as system workout app does. It supports digital crown and dynamic show indicator and custom color.
So , how to implement that vertical scroll effect?
I updated my project from watch app + extension to single-execute project with Xcode 15.
Then add a widget target to watch app.
The new WidgetKit swiftUI complications works well on simulator, but not shown on the real device.(can not find on Apple Watch Face Complication Editor or rectangle widget)
I tried:
clean xcode build && Derived Data.
reboot my watch/iphone
delete all old clockkit complication settings & complicationcontroller.swift
the watch still show old clockkit complicaton , that very buggy. so I try next:
4. restore my watch and pair it again.
The new WidgetKit complication still not shown, it very frustrated.
Do I have to change my old watch app to swiftUI lifecycle project to work?
But code is works onthe simulator, which doesn't make sense.
when I debug widget extension on Xcode, it show error:

SwiftData CloudKit integration requires that all attributes be optional, or have a default value set
After install XCode 15 beta 6:
@Model
class WordResult {
var text = ""
var translation:[String] = []
init(){
}
}
got this error:
Variable 'self._$backingData' used before being initialized
so I changed to :
@Model
class WordResult {
var text:String
var translation:[String]
init(){
self.text = ""
self.translation = []
}
}
Then got this:
CloudKit integration requires that all attributes be optional, or have a default value set
It seems it can not work with cloudkit now.
