Appcode 2018.1 Swift code completion


Appcode 2018.1

In a very large objective c code base and many subprojects.  I just started incorporating some swift and code completion is VERY slow.  Even typing in a swift file can lag showing typed characters for several seconds.

I've set the memory limit up to -Xmx2500m

IDE runs fine w/ objective c files but really is unusable with swift at this point.
