Compiling Swiftly One of the most well know “features” of the Swift language are the slow build times. Embracing the future shouldn’t make developers slower due to long build times. But how do you analyze your builds? Pointing Instruments at Xcode during a build won’t help very much. It turns out there are some secret and not so secret switches and dials in Xcode we can use to find out the bottlenecks in our builds, and we’ll also go over some simple code examples of how to write code that builds fast.
