Hi there. I've noticed and is logical that version 2.2 of Foundation requires iOS 13 and XCode 11, because there are new implementations that are not recognized if compiling with Xcode 10. So I've downloaded 2.1 and everything is fine with my iOS 12 and XCode 10. The question is, I want to develop an application, there will be two branches or do I have to be stuck with 2.1 until iOS 13 is released? No problem with that but I don't want to install iOS 13 in my iPhone until release. Thanks in advance.
