Xcode 6.3 autocompletion slow with bridging header (e.g Parse)

Question

tl:dr

Xcode Update 6.3.1 solved the problem for me. It's still lightly slower than before but I'll give that shame to my Evo 840.

the problem

Since I've installed the latest Xcode version (6.3) my projects with bridging headers seem to have problems with autocompletion. It's incredibly slow!

Is there any known workaround (except removing bridging headers...)?

Answer 1

I had similar issues and after updating to xcode 6.3.1 and swift 1.2 they dissapeared.

Not appearing with xcode 7 & swift 2.0
