I think some feature is not working on macOS 15.

I know that macOS 15 is not yet supported, just reporting this as an issue, so it can be fixed when support for it is added!

I can confirm that this works for me as well.

@tony-sol did you have to install full xcode or just the xcode command line tools? I'm trying to avoid having to install full blown xcode but I am at a point where after upgrading from MacOS 14 --> 15 I cannot get any homebrew casks to upgrade correctly.

Installing just cli-tools didn't help me, so i installed full XCode from AppStore

dcchambers Jan 27, 2025

@tony-sol Thanks for the quick reply!

I followed the suggestion in this similar discussion and grabbed the Xcode command line tools manually from the apple developer website instead of using the xcode-select --install command and installed the 16.2 CLT that way and now homebrew cask upgrades are working again without the weird swift error.

It looks like (at least in 15.2) xcode-select --install does not install the right command-line utility in certain cases. Manually downloading from https://developer.apple.com/download/all/ and installing it solves this problem.
