I had this problem with Xcode 7, was fixed in 7.1 and now is back in 7.1.1.
I have a workspace, with a couple of cocoapods in it as well, and on compile Xcode just hangs at "Precompiling 1 of 1 prefix headers". Nothing I try seems to fix it, cleaning the build etc.
I know the pch files were removed for new projects, but this is an older one (which, again, was working just fine in 7.1), and the header variables are fairly intricately linked across the proejct. This is a bad practice, but alas, the code base is legacy.
Any ideas?
