Xcode 8.0 Swift 3.0 slow indexing and building

Question

I\'ve installed Xcode 8.0 and converted Swift 2.2 to 3.0 (that process also took a lot of time, I just left my Mac running all night). I have not a big project (about 20 fil

Answer 1

This works for me in Xcode 8.2.1 and Swift 3 when "Indexing" is stuck:

I always have two projects open, a dummy project and the project I'm working on. I also have a iPad Air device connected that I run my projects on. When my project gets stuck on "Indexing", I switch to my dummy project and run my project on my connected iPad Air device. Then I stop the project and switch back to the project I'm working on and the "Indexing" is magically finished. This should also work with the simulator only, if you don't have a physical device connected.
