The time picker is implemented using a UIPickerView.

Tutorial for "UIPickerView - Loop the data" involves "simply create a picker view with a large enough number of repeating rows that the user will likely never reach the end".

I guess Apple didn't think OP would reach the end.

I think you could fake it by automatically snapping the user back to the middle when they reach the top or bottom. Still not “infinite scroll”

they do kinda fake it already. If you switch to another app, then switch back to the Clock or Calendar apps, it’ll snap you back to the top of the list
