Xcode iOS 8 Keyboard types not supported

Go to iOS Simulator-> Hardware-> Keyboard -> Uncheck the Connect Hardware Keyboard Option. This will fix the issue.

This message comes when the keyboard type is set to numberPad or DecimalPad. But the code works just fine. Looks like its a bug with the new Xcode.

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

then the software keyboard will be displayed once again.

If you're getting this bug with Xcode Beta, it's a beta bug and can be ignored (as far as I've been told). If you can build and run on a release build of Xcode without this error, then it is not your app that has the problem.

Not 100% on this, but see if this fixes the problem:

iOS Simulator -> Hardware -> Keyboard -> Toggle Software Keyboard.

Then, everything works
