ios - Keyboard Extensions Xcode 6.3? -

everything working when debugging keyboard on xcode 6.2 running ios 8.2. after updating xcode 6.3 , ios 8.3, seem having difficulty getting debugger work. has experience similar problems? i've tried cleaning build, uninstalling/installing app, nothing seems work.

what happens build , run, , when switch between keyboards mine never pops up, instead jumps default one. upon ending task, , doing again works perfectly, not when i'm attempting debug.

some of information answer bit outdated, useful me. still convinced extension debugging on devices 90% broken xcode 6.3.2 , ios 8.3. i've been debugging simulator, though, , i'll device process attach correctly within xcode, more not quits on me.
