I updated to the newest Xcode version 7.1.1 in the hope, that the performance will be better. But no, performance is much worse again.
When typing a word, an indexer starts immediately and CPU is on max. In general there is mostly a process running full, even I am doing nothing. There are no other apps open, but the CPU is mostly running. (mdworker, WindowServer, Xcode, SourceKitService…)
I already disabled Spotlight from indexing my source code.
Are there any hints, tutorials or the like to tune OS X and Xcode, so it will be more performant. I am using Swift as programming language.
