Hi, I'm Matt and I'm an OS kernel engineer. Today, I'll teach you how to use Instruments to optimize code for Apple silicon CPUs. Using CPU resources efficiently can avoid noticeable wait times when your app needs to process large amounts of data or quickly respond to an interaction. But predicting how software performs is difficult for two reasons. The first is the layers of abstraction between your Swift source code and what actually ends up running. The source code you write for your app is compiled into machine instructions that eventually execute on a CPU. But your code doesn't run…
