Hi. I am developing an alarm app. My app plays white noise to help users get into sleep properly. To keep white noise playing in the background, my app uses audio background mode. The problem is that my app sometimes gets suspended few hours after getting into background. I cannot find the exact reason for it.
Doesn't audio background guarantee that app is not suspended by system? Then how can I handle this issue so that my app can keep white noise playing feature?

I found a very strange bug while using SwiftUI, and the following code is the minimum required to reproduce it.
When I press the 'Go to page2' button, the CPU load goes to 100% and the memory usage keeps increasing. What's wrong with this code?
I tried to search for a day but could not find any answer.
import SwiftUI
struct ContentView: View {
var body: some View {
NavigationStack {
Page1()
.environmentObject(Foo())
}
}
}
class Foo: ObservableObject {
init() {}
}
struct Page1: View {
u/EnvironmentObject
private var viewModel: Foo
u/Binding
var value: Int
init() {
self._value = .init(get: { 0 }, set: { _ in })
}
u/State
private var id: UUID? = nil
var body: some View {
NavigationLink(value: 0) {
Text("Go to page2")
.padding()
.foregroundStyle(.white)
.background(.black)
.cornerRadius(12)
}
.navigationDestination(for: Int.self) { _ in
Page2(
onComplete: {
print("value", value)
}
)
}
}
}
struct Page2: View {
public init(onComplete _: u/escaping () -> Void) {}
public var body: some View {
Text("This is Page2")
.task {
print("hi")
}
}
}
