Continuing from the previous version, I upgraded to Swift 3 and Xcode 8 (beta 4). Most of the glitches are gone, but every now and then one shows up. So I’m not entirely sold on the whole thing yet. I’m still having doubts if it wouldn’t be simpler to just have the user enter text in a separate popup of some kind, and only display read-only views in the actual table. The problem with that is that it is a lot less intuitive and user-friendly. OTOH, it would work… I get a feeling Apple really doesn’t want us to do editing in text views in table cells. I don’t think any of Apple’s own apps do that.
A problem I needed to solve was: while editing in a text view, I want the view to grow and shrink depending on the text entered. I also want this to work in conjunction with auto-layout.
