Xcode 27

15 September 2026 at 21:55

Xcode 27 includes Swift 6.4 and SDKs for iOS 27, iPadOS 27, tvOS 27, watchOS 27, macOS 27, and visionOS 27. Xcode 27 supports on-device debugging in iOS 17 and later, tvOS 17 and later, watchOS 10 and later, and visionOS. Xcode 27 requires a Mac running macOS Tahoe 26.6 or later.

Peter Witham:

Is this new in Xcode 27? Pretty sure it as and I approve whole heartedly! I really hate setting up Xcode settings more than once.

Christian Beer:

Building with Xcode 27 doesn’t work because of some intransparent XCStrings error… and I even can’t check with Xcode 26 anymore because Apple decided to not let me run it on macOS 27…

Steven Woolgar:

After all these years Apple has finally broken cmd-e in Xcode 27.

Update (2026-09-18): Jesse Squires:

Xcode 27 seems to have broken UI appearance vs Editor appearance. They used to be separate settings.

For example, previously, the app could be light mode while the editor theme was dark.

But now, you choose a dark editor theme and the whole app goes to dark mode.

I hate this.

Me, too.

Update (2026-09-24): Christian Beer:

generate stubs for protocol: uses wrong class names

fix for missing parameter: inserts it at the wrong position

generating init with Bindings, State, etc.: mostly wrong

Update (2026-10-01): Steve Troughton-Smith:

AI code completion was such a nothingburger, for all of that investment. I don’t even have it turned on in Xcode anymore. If you’re into code completion, you’re into using Codex and Claude, so why would you ever use it now.

The built-in Xcode stuff has pretty much never worked at all for me. I either get errors or it does nothing.

Clear and Tinted Icons Are a Hard Pass

Adam Engst:

Of the TidBITS readers who chose to respond to the poll, only 1% said they use clear icons on the Mac, and no one admitted to using tinted icons. On the iPhone, clear icons were twice as popular—a whopping 2%—and just 1% of respondents said they use tinted icons. Dark icons, which retain color, were slightly more popular, but still couldn’t exceed single digits, with 6% on the Mac and 9% on the iPhone.

Squircle Jail is one thing; redesigning icons to be assembled within Icon Composer is another. The latter makes a lot less sense but for supporting clear and tinted icons.
