Cannot debug

I haven’t tried building an iOS app in some time.
I have a simple one that I’d like to knock out, and should be able to quickly, but I can’t run in the debugger anymore, despite Xcode being installed and up to date. And I can see that the debugger launches from Xcode.

Anyone know the fix?

Thats the problem.
Its too new for Xojo.
You need Xcode 8 apparently. Cant debug in 64 bit mode.

OK… I had Xcode 8 and it wouldn’t run so I upgraded.
Is there a way to downgrade?


Is there any place on the Xojo Website that states which version of Xcode is compatible with each Xojo Release?
