What am I doing Wrong on trying to make an iOS app?

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?

HELLLPPPPPP

versions of Xojo prior to the just released 2019r2 would not work with XCODE 11
