It seems as of now apple didn't get support for debugging extension into simulator. I was having same issue but I observe that We can debug code if we execute application into device as below.

1) Choose your Keyboard extension target.

2) Go to Edit Scheme.

3) In info tab select your Executable from drop down and check the option "Debug extensions and XPC services".
