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. We’ll show you how Xcode makes it simple to build a universal macOS binary and go through running, debugging, and testing your app. 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’ve designed this session for experienced macOS developers who want to get their existing apps running natively on Apple Silicon Macs. You can learn more about doing so in the Apple Silicon documentation.For more information on the transition to Apple Silicon, watch 'Explore the new system architecture of Apple Silicon Macs', 'Bring your Metal app to Apple Silicon Macs', and 'Optimize Metal Performance for Apple Silicon Macs'. And to learn how to run your iPhone and iPad apps on Mac, check out 'iPad and iPhone apps on Apple Silicon Macs'.

Apple Maps provides users with better travel planning features, such as a 360-degree view of a location on Look Around, personalized restaurant and park guides and guides organized by companies. You will see cycling options and charging points for electric vehicles. Development Tools. So Apple, you’re loosing a customer, but you don’t really care, do you? The new Xcode and macOS regressions case¶ WWDC 2020: Apple, tool or toy?¶ Initially posted on 27 June 2020. The major announcement at the WWDC 2020 was the transition of processors from Intel to home-made ARM-based, to be started by the end of 2020 and completed by 2022.

The shapira manuscriptrejected scriptures bible. In macOS 11, when running on Apple silicon, the CPU tab of the Activity Monitor.app has a new
Kind column showing which architecture each process runs on ('
Apple' means it's running natively in Apple Silicon,
Intel when the process is being translated via Rosetta):
Your apps and most executable code in macOS, are stored in a file format called Mach-O.
These files can either be targeting a single CPU architecture or they can be universal (a.k.a. support multiple CPU architectures).
To examine a file on disk, you can use the
4 kB, on Apple Silicon it's
16 kB: therefore the
PAGE_SIZEmacro is no longer a constant. Use:
PAGE_MAX_SIZEfor a compile-time upper bound
vm_page_sizeto read the actual value at runtime
#if os(iOS) && !targetEnvironment(simulator)
When building for Apple Silicon you might encounter linker warnings (that later translate in some cryptic errors) similar to:
ignoring file when building for macOS-arm64, but attempting to link with file built for macOS-x86_64..
This happens when we have a binary dependency that hasn't been built as universal yet, the only way to fix this is to:
What you can do now: search for precompiled binaries in your project (
.xcframework) and reach out their vendors if the binary is not universal (use
lipo --info path/to/binary to inspect them)
Precompiled binarieschapter above)
In Instruments you can see which core is which by the associated label:
If your app supports plug-ins, it will typically discover them at runtime and then load them when needed.
That's called an in-process plug-in model, and typically the app uses a call to
Bundle.load() for this.
Alternatively, the plug-ins can be spawned as new processes, and we call those out-of-process plug-ins. The app and the plug-in process then use some interprocess communication mechanism like XPC. Loading another plug-in typically spawns another process.
|1st party (build from source code shipped inside your app)||3rd party (precompiled binaries, shipped inside the app or separately)|
|Out-of-process||Supported||Supported, even when the binary is intel only (Rosetta will take care of that process)|
|In-process||Supported only if the running architecture matches the one in the precompiled binary)||not supported|
