![]() ![]() And the first step here is building your apps as universal. ![]() Let's now focus on getting your apps ported over to run natively on Apple Silicon Mac computers. They're all being transparently translated by Rosetta. So if you perhaps happen to use the debugger to look at individual CPU instructions, you'll notice that they are Intel instructions. All aspects of development from Xcode, including testing, debugging, and profiling are supported, and it's all translated on the fly. In Activity Monitor, the app now shows as Intel CPU. Pressing Run will build the code for Intel and then run it in Rosetta. As we've noticed before, the run destination in Xcode allows you to target Rosetta. Xcode fully supports building and running apps for Rosetta. You also cannot use Rosetta for kernel extensions, AVX vector instructions, or virtualization. You cannot load native code into a translated process or vice versa. In Rosetta, the entire process is always translated. If you have any existing Intel only apps, or if for some reason you can't start building your app natively right away, Apple Silicon computers have Rosetta, a translation environment that can seamlessly run these.

You can learn more about doing so in the Apple silicon documentation. We've designed this session for experienced macOS developers who want to get their existing apps running natively on Apple silicon Macs. Learn what changes to low-level code you might need to make, find out how to handle in-process and out-of-process plug-ins, and discover some useful tips for working with universal apps. We'll show you how Xcode makes it simple to build a universal macOS binary and go through running, debugging, and testing your app. Your porting questions, answered: Learn how to recompile your macOS app for Apple silicon Macs and build universal apps that launch faster, have better performance, and support the future of the platform. ![]()
