[ios sim only]: iOS 16.4 simulator textChange behavior note

[cjohn001]

Update: I think the source of the problem is NativeScript/NativeScript#10267. This bug should be reopened.

The issue is similar to the closed bug

#22

When changing a value in a text field bound to a FormGroup/FormControl the FormControl is not updated with the new value but the previous value. Hence input validation does not work.

Unfortunately the workaround described in the previous issue does not work.

I just found out that the problem seems to only appear on the ios simulator, not on real devices and not on Android at all.

Appears to be completely isolated to iOS issue alone: https://developer.apple.com/forums/thread/727715
Can confirm that delegate method is indeed called twice (not {N} related) - just as described there (only under certain circumstances).
At moment, this stands at a iOS sim only issue using that specific version as mentioned in that forum.
