This is not a bug, this is a feature.

(Apple deliberately make pressing ' switch back to the alphabetic plane for contractions like "Peter's".)

(And tapping space twice gives a period is also a feature. It's even documented.)

If you want to modify this feature, the whole UIKBKeyboard class of the keyboard layout needs to be changed at runtime, which means "private API" etc.
