Xcode 15.1
Xcode 15.1 includes SDKs for iOS 17.2, iPadOS 17.2, tvOS 17.2, watchOS 10.2, and macOS Sonoma 14.2. The Xcode 15.1 release supports on-device debugging in iOS 12 and later, tvOS 12 and later, and watchOS 4 and later. Xcode 15.1 requires a Mac running macOS Ventura 13.5 or later.
There’s a bug in Xcode 15 that prevents apps from running on macOS versions older than 13. There’s another bug doing the same thing for 10.13 and older. You can’t use Xcode 14 on Sonoma, so good luck getting out working builds! No urgency getting a fix out.
It looks like these are finally fixed. I have a few more things to check, but it seems I’ll now be able to update my main Mac to Sonoma.
It sounds like it also fixes this CPU use issue with the iOS Simulator (via Jon Reid).
TIL: in Xcode 15 you can press right-arrow-key in suggestions to just use select options[…]
Xcode’s autocomplete could really use an option to use line breaks if a function has more than N parameters to it.

Update (2024-01-03): ShikiSuen:
I am using Xcode 15.1 to compile my project against macOS 13.1 SDK (targeting macOS 10.9). The compiled app ridiculously asks for SwiftUI support on macOS 10.9 and macOS 10.13.6.
Agreed about support for automatic new line insertion, but Xcode does have, probably as a new feature of Xcode 15, a “Format to Multiple Lines” menu command which helps a lot.
