OK - ignoring that problem and on to the next.
FIrst, I have to say the course was terrific. It’s been decades since I wrote any serious code and, somehow, PL/1 skills don’t help much these days. Your course has me writing the productive app I wanted within days. Thanks!
So - made progress on my app and it seems to be working well on iPhone simulator. Decided to try it on an iPad simulator since that’s what I really want and when I run it on the iPad Air simulator, all my lists are empty. Couldn’t find anything obvious so I went back to the TaskList app from the course and when I run TaskList on an iPad Air simulator I get a blank white screen! TaskList runs fine an iPhone simulator.
I’ve tried it on both 11.1 and the 11.2 beta with same results
