The app puts button values into a text view area and controls the cursor. Upon an IOS touch screen, cut or paste, the IOS cursor loses sync with the app cursor causing an address out of bounds and fails.
The IOS cut or paste changes the cursor position and the text.endIndex address by shrinking or expanding the text field. IOS doesn't know about the app cursorPosition. If IOS could update the app cursor position and the text.endIndex position would solve the problem. Or if the app knew about the IOS change could update the app cursor position and the text.endIndex.
The current work around is the user sets the cursor to the text.startIndex using an app navigating button before the touch screen. The app does not fail. The user then navigates the cursor using arrow buttons to another position.

TSIs have been requested with engineer suggestions for well over one year. I hope someone could figure this out.
I just finished SummaGram iPhone and would like to host it.
Thanks for your help.
