I want to generate randomised MKLookAroundScene for my world exploration app (think geogussr functionality). How can i achieve that with MapKit? I have tried
struct LookAroundView: View {
@State private var lookAroundScene: MKLookAroundScene?
@State private var yOffset: CGFloat = 0
func generateRandomCoordinate() {
let minLatitude = -90.0
let maxLatitude = 90.0
let minLongitude = -180.0
let maxLongitude = 180.0
let randomCoordinate = CLLocationCoordinate2D(
latitude: Double.random(in: minLatitude...maxLatitude),
longitude: Double.random(in: minLongitude...maxLongitude)
)
checkLookAroundAvailability(coordinate: randomCoordinate)
}
func checkLookAroundAvailability(coordinate: CLLocationCoordinate2D) {
Task {
let request = MKLookAroundSceneRequest(coordinate: coordinate)
if let scene = try? await request.scene {
DispatchQueue.main.async {
self.lookAroundScene = scene
}
} else {
generateRandomCoordinate()
}
}
}
var body: some View {
Group {
if let scene = lookAroundScene {
LookAroundPreview(initialScene: scene)
} else {
Button(action: {
generateRandomCoordinate()
}) {
Text("Generate Random Coordinate")
}
.offset(y: yOffset)
}
}
}
}
but it didn't work. I put the yOffset change there to debug, and it seems that self.lookAroundScene = scene never gets executed.
If there are any other options, please let me know!
Have you tried catching the error from your try await request.scene? I have just finished a similar task and no issues. Perhaps also try using MainActor.run so that you are not combining async/await with DispatchQueue? I've heard others having issues when mixing the two.
Task {
do {
let request = MKLookAroundSceneRequest(coordinate: coordinate)
let scene = try await request.scene
await MainActor.run {
self.lookAroundScene = scene
}
} catch {
print(error.localizedDescription) // This will help!
generateRandomCoordinate()
}
}
