ios – SwiftUI ActivityKit error `unsupportedTarget` when following Flo’s YouTube tutorial

In the meanwhile I am following Flo’s YouTube video on exercise package and tips on how to use it to create stay actions on the lock display screen (I’ll discover creating dynamic island characteristic later however for now, I simply need a stay exercise).

I’ve created the exercise as follows:

The code:

Widget file containing the widget

That is inside a separate widget goal.

import WidgetKit
import SwiftUI
import ActivityKit


struct TimerView : View {
    let context: ActivityViewContext

    var physique: some View {
        VStack {
            Textual content(context.attributes.timerName)
                .font(.headline)
            
            Textual content(context.state.endTime, model: .timer)
        }
        .padding(.horizontal)
    }
}

struct OfflineWidget: Widget {
    let variety: String = "OfflineWidget"

    var physique: some WidgetConfiguration {
        ActivityConfiguration(for: LiveActivityTimerAttributes.self) { context in
            
            TimerView(context: context)
            
            
        } dynamicIsland: { context in
            DynamicIsland {
                // Expanded
                DynamicIslandExpandedRegion(.backside) {
                    Textual content("Dynamic island is not supported but")
                }
            } compactLeading: {
                Textual content("Dynamic island is not supported but")
            } compactTrailing: {
                Textual content("Dynamic island is not supported but")
            } minimal: {
                Textual content("Dynamic island is not supported but")
            }

        }

    }
}

In my fundamental view (Inside the principle swiftUI goal), I’ve:

@State non-public var exercise: Exercise?

…

Button("Begin stay exercise") {
                    // Create attributes
                    let attributes = LiveActivityTimerAttributes(timerName: "Dummy timer")
                    
                    // Create preliminary state
                    let state = LiveActivityTimerAttributes.ContentState(endTime: Date().addingTimeInterval(60))
                    
                    let content material = ActivityContent(state: state, staleDate: nil)
                    
                    // Request to begin exercise
                    do {
                        exercise = attempt Exercise.request(
                            attributes: attributes,
                            content material: content material,
                            pushType: nil // NEED to move nil right here. Defaut is to permit push notifications to replace the stay exercise
                        )
                    } catch {
                        print("Error requesting stay exercise: (error)")
                    }
                }
                
                Button("Cease stay exercise") {
                    // Replace exercise state
                    let state = LiveActivityTimerAttributes.ContentState(endTime: .now)
                    
                    // Request exercise to finish
                    let content material = ActivityContent(state: state, staleDate: nil)
                    
                    Activity {
                        await exercise?.finish(content material, dismissalPolicy: .instant)
                    }
                }

The issue:

Nonetheless once I run the app in an iOS 18.1 simulator I get the ActivityKit.ActivityAuthorizationError.unsupportedTarget error output to me, and naturally no stay exercise, not even a lifeless one. I additionally get this when operating on an actual machine.

In line with Apple’s documentation, the unsupportedTarget error happens when…

the app doesn’t have the required entitlement to begin a Stay Actions.

The query:

What entitlements is it talking about right here?

a. Is it talking a couple of particular Stay Actions goal, effectively in my Xcode I see nothing of the type:

b. Is it as a result of I’m on an Apple free developer account? Through which case, why would this be limiting me as I ensure that to set the pushType: nil once I request a stay exercise.

I would actually recognize just a little assist, thanks!
