title: Xcode is running really slow
body: <p>I've recently tried to use Xcode 8 to make iOS apps and to test things in Swift however it is impossible to work on as doing a simple 'print("Hello World")' takes easily over a minute to process to print it to the console, I tried doing regular development as well by creating UI buttons etc. but when I try to compile it, it is too slow to work and that is with simple things. My computer is the Mid 2012 Macbook Pro Non-retina with 4GB of RAM, not a quick computer but I can program in Python without these problems. If anyone knows some solutions please tell me! Thanks.</p>
