OK so I made the silly mistake of upgrading my Mac. Installed all back as it should be apart from I can't run or build iOS apps.
I have Xcode 9.4.1 or 10.1 and have set the command line tools to be 9.4.1 in both
I can run on 9.4.1 an test app in Xcode and works fine.
I am running Xojo 2018r4
Mac OS 10.14.6
When i goto Xojo the run and build is greyed out.
In Xcode if I goto product and destination i have 11.4 and 12 after the iPad names etc
In Xcode preferences components Ive downloaded 10.3.1, 9.3, 8.3 simulators
Ive now spent a week on different ideas.
Somebody else MUSY have updated and had the same problems?
