Can't find keyplane that supports type 4 for keyboard iPhone-Portrait-NumberPad; using 3876877096_Portrait_iPhone-Simple-Pad_Default

I too had this problem after updating to the latest Xcode Beta. The settings on the simulator are refreshed, so the laptop (external) keyboard was being detected. If you simply press:

iOS Simulator -> Hardware -> Keyboard -> Connect Hardware Keyboard

so that the entry is UNchecked then the software keyboard will be displayed once again.

The emulator tries to find a numeric keypad on the mac, but this is not found (MacBook Pro, MacBook Air and "normal/small" keyboard do not have it). You can deselect the option Connect Hardware Keyboard or just ignore the error message, it will have no negative effect on application.

Just Go to

iOS Simulator -> Hardware -> Keyboard -> Uncheck the Connect Hardware Keyboard Option.

This will fix the issue.

Your MAC keyboard will not work after performing the above step, You have to use simulator keyboard.
