With Xcode 11 and Xojo 2019.3 it seems I can only create apps that run on iOS 13.
The Xojo docs indicate I should be able to make apps that run on iOS 10 - 13.
What is needed to do this?
@Bob G But at the moment I can only create apps that run on iOS 13.
Xojo can run iOS apps pre-iOS 13 in the iOS Simulator but you need to download a Simulator for each OS. This is done in Xcode > Preferences > Components (see screenshot below).
