Xcode 16.1
Xcode 16.1 includes SDKs for iOS 18.1, iPadOS 18.1, tvOS 18.1, watchOS 11.1, macOS Sequoia 15.1, and visionOS 2.1. The Xcode 16.1 release supports on-device debugging in iOS 15 and later, tvOS 15 and later, watchOS 7 and later, and visionOS. Xcode 16.1 requires a Mac running macOS Sonoma 14.5 or later.
I’m not sure why it’s reported in the macOS 15.1 release notes instead of in the Xcode release notes, but an important bug seems to be fixed:
Fixed: Back-deploying apps that link QuickLookUI to macOS 11 or earlier might crash. (133213738) (FB14667312)
Unfortunately, FB13820420, where Swift apps that use the Network framework crash at launch on macOS Ventura and earlier, was introduced in Xcode 15 and is still not fixed.
When I enabled Apple Intelligence and launched Xcode 16.1 on macOS 15.1, it offered to download an AI model, and I see that there’s an Editor ‣ Show Swift Assist menu command. However, Swift Assist does not seem to be available yet, only the predictive code completion feature.
