We are experiencing an issue with withCheckedContinuation in our Swift project. Our implementation was working perfectly in a previous version of Xcode and continues to work in the simulator. However, it fails to work on a real device. Here’s a brief description of the problem: • Environment:
- Xcode Version: Xcode 16.0 Beta 5
- Swift Version: Swift 5
- OS: IOS18 beta 5
• Problem: The code using withCheckedContinuation behaves as expected in the simulator but fails on a physical device. We are receiving a “bad access to memory” error when running on a real device.
• What We’ve Tried:
- Verified that the code works in previous Xcode versions.
- Tested on different simulators, where it runs without issues.
- Checked for any obvious errors in memory handling or threading.
Code Example: Here’s a simplified version of the problematic code:
var body: some View {
VStack {
Text("Hello, world!")
}
.padding()
.onAppear {
Task {
await self.checkTrialOrIntroductoryDiscountEligibilityAsync()
}
}
}
func checkTrialOrIntroductoryDiscountEligibilityAsync() async {
return await withCheckedContinuation { continuation in
checkTrialOrIntroDiscountEligibility() {
continuation.resume()
}
}
}
func checkTrialOrIntroDiscountEligibility(completion: () -> Void) {
completion()
}
}
