I recently upgraded to Xcode 6.2. It seems like there is a weird bug. For example, if I want to change the bundle id, the textfield will lose focus after any character I type.
Is anyone having the same issues? Does anyone know how to fix that?
It's just quite annoying for me, and I guess for anyone else too.
I also think so it's weird thing, and you need to try change bundle id in the Info tab not in General tab
If you get the problem in "General" tab (same to me), you should modify those infos in "Info" tab if possible. That is my workaround for this bug.
