I'm trying to execute a background task following the Developer Documentation.
This is my code
import SwiftUI
@main
struct MyAppTest_Watch_AppApp: App {
@Environment(\.scenePhase) var scenePhase
let bs = BackgroundSession()
@SceneBuilder var body: some Scene {
WindowGroup {
ContentView()
}.backgroundTask(.appRefresh("prova")) { context in
print("bg task")
await scheduleTask()
}
.onChange(of: scenePhase) { phase in
switch phase {
case .active:
print("\(#function) REPORTS - App change of scenePhase to ACTIVE")
case .inactive:
print("\(#function) REPORTS - App change of scenePhase Inactive")
case .background:
print("\(#function) REPORTS - App change of scenePhase Background")
WKApplication.shared()
.scheduleBackgroundRefresh(
withPreferredDate: Date.init(timeIntervalSinceNow: 5 * 60.0),
userInfo: "prova" as NSSecureCoding & NSObjectProtocol, scheduledCompletion: schedule)
default:
print("\(#function) REPORTS - App change of scenePhase Default")
}
}
}
func scheduleTask() async {
bs.testSession()
await WKApplication.shared()
.scheduleBackgroundRefresh(
withPreferredDate: Date.init(timeIntervalSinceNow: 5 * 60.0),
userInfo: "prova" as NSSecureCoding & NSObjectProtocol, scheduledCompletion: schedule)
}
func schedule(error: Error?) {
if error != nil {
// Handle the scheduling error.
fatalError("*** An error occurred while scheduling the background refresh task. ***")
}
print("Scheduled!")
}
}
On the simulator the background refresh occurs correctly according to the preferred date and executes the background task, on the real watch it does not.
I also set the app as complication in my watch face.
The device I'm testing the app on is an Apple Watch Serie 7 with watchOS 10.3.
Any idea?

Hi everyone,
I would like to know if it is possible to make a url fetch within a Timeline View.
Thanks
Hello,
I have a TabView containing multiple views where one of them contains a list of items. The digital crown on the apple watch does not allow me to scroll the items in the tabview but only scrolls the list of items. Is there any way to disable that the scrolling of the list is done by the wheel or even a way to prioritize the digital crown to scroll the tabView and not the list?
Thanks
