2. Selecting and deleting a word also deletes a space to the left of it, but in this case onSelectionChange fires first

Regarding this issue.

This is the default iOS behaviour.
I checked this on system messaging app. Shared recording for reference.

Simulator.Screen.Recording.-.iPhone.15.Pro.-.2024-07-10.at.15.55.35.mp4

Findings:

• textView(_:shouldChangeTextIn:replacementText:) [UITextField delegate method] will be called first when we press backspace on keyboard with replacement string "". This will detect that text on Edit Text to be changed(Not reflected yet) and return YES from this function.
• Returning YES from this function will further call textViewDidChangeSelection[UITextField delegate method] with removed one left space character.

Solution:

• Since we didn't have any callbacks now where that one extra space is removed. We can live with this default behaviour.
• Or else we can keep previous text from textView(_:shouldChangeTextIn:replacementText:) method and check if text got changed in textViewDidChangeSelection then add that extra space. [Here, lots of edge cases needs to handled]

For this issue:

For the multiline textinput, for the first keypress onSelectionChange fires first, but for later key presses onChangeText/onChange fire first

I started debugging on this.
