It does to work on any device running any version of iOS.

If the VC is automatically created can I get to the source and set a breakpoint in it?

I have already tried IPSW.ME but the unsigned version is not accepted as you mentioned. Anyone any other suggestions please?

I had another storyboard so deleted it. Could not get segue to work so using instantiate which does. Now all I have to do is sort out the GameView layout but that's another story. Thank you.

I am sorry to have to ask but what big blue banner? I cannot see one in iMovie so please tell me where it is. p.s. I am new to Mac, less than 1 year, even newer to iMovie, 2 days, but have over 40 years experience in Computing.

I tried doing let _ = Timer.scheduledTimer(withTimeInterval: 1.0, repeats: true) { myTimer in print("My Timer Fired") } and got property declaration does not bind any variables so tried     var gameTime = 0.0 var aTimer: Timer     func myTimer(tick: Double) { gameTime += 1 } and in my InitGame function I added     aTimer = Timer.scheduledTimer(withTimeInterval: 1.0, repeats: true) { _ in myTimer(tick: 1.0) }      and that worked for me.

just to say thank you. I have completed the 'fixes' for the warnings and sorted out the access rights to my key in the key chain so the build completed and I can proceed with submission once I am ready for that step. For me this situation is resolved.

I have subsequently found a bug in Unity build settings process. If I do not select automatic signing it requires a provisioning profile id. If you enter one and then decide to switch to automatic signing the provisioning app id is not changed to "Automatic" as it should be according to the message I received. I will update my Unity forum ticket. This problem is now solved.
