How to open RoomPlan data on devices without a LiDAR Scanner

I've saved my RoomPlan.CapturedRoom in CoreData as a Data object. When I open it again on a device WITH a LiDAR Scanner, it works totally fine. However, when I try to open it on the simulator for example, I get an error saying "RoomPlan.CapturedRoom.Error.deviceNotSupported".

The code I use to convert the Data back to a CapturedRoom is this:

let decoder = JSONDecoder()
            
do {
    self.capturedRoom = try decoder.decode(CapturedRoom.self, from: capturedRoomData)
} catch {
    let nserror = error as NSError
    fatalError("Unresolved error \(nserror), \(nserror.userInfo)")
}

The fatalError is thrown here giving me the error above.

Solution

  • The solution posted by @Darkwonder is the right approach to this: "You can write your own class and map it to Apples CapturedRoom, and implement Codable. Another solution is to export the CapturedRoom to JSON."
