iOS9: UIDatePicker with datePickerMode of UIDatePickerModeTime only shows Hours, and no Minutes

Question

I\'m using Xcode beta 7 with the iOS9 simulator. Using a UIDatePicker with a datePickerMode of UIDatePickerModeTime only shows Hours, and not minutes.

See screenshot:

Answer 1

Found a useful description of this problem in the iOS 9 release notes - seems I should be reading these more carefully.

UIPickerView and UIDatePicker are now resizable and adaptive—previously, these views would enforce a default size even if you attempted to resize them. These views also now default to a width of 320 points on all devices, instead of to the device width on iPhone. Interfaces that rely on the old enforcement of the default size will likely look wrong when compiled for iOS 9. Any problems encountered can be resolved by fully constraining or sizing picker views to the desired size instead of relying on implicit behavior.

In my case all I had to do was remove all constraints on the UIDatePicker and then "Reset to Suggested Constraints". Rebuild and now all is well.
