Xcode release 12.2, both iOS 13 and 14. Both on device and simulator. The work
I did on the app was trying to get the split view controller with the new APIs
to behave like when used with the old APIs. I finally gave up after trying
every possible combination of style and behavior. My app was originally
designed 5 years ago. There might still be stuff that is impacting the new
APIs, although I did search for all occurrences of the split view controller
and isolated the few calls I had with @available to leave the new APIs do their
job. But, I don’t see how this is related to all textfields and textviews now
being unable to work with the keyboard!
