I feel like I am being forced to upgrade to Catalina. I am trying to build an iOS app and am having issues with Xcode 9 and Xojo 2019r3.1 recognizing the development profile. I’ve been told I need to upgrade to Xcode 11. However, Xcode 11 needs Catalina and I am currently running High Sierra (10.13.6). I’m deathly afraid to upgrade to Catalina. With all the restrictions and “security” features of the OS, I am afraid half the tools I use (32 bit apps?) will be completely worthless.
So does anyone have any recommendations? What do I need to look out for as I upgrade? Are there utilities I need to install that Apple has removed (like the removed Telnet in either 10.12 or 10.13).
