Xcode 26 installation error on macOS Tahoe

Hey guys, I updated to macOS Tahoe and after that I tried installing Xcode 26, but I always get an error message saying it can’t complete the installation, both through the App Store and via direct download from Apple’s website. Is anyone else having this same issue?

I have the same issue. Super annoying as the main motivation for upgrading macOS was to try the updated Xcode.

I rebooted and just kept trying. Around the 5th or 6th time it was successful

@philmctim FYI - Xcode 26.0 runs on macOS 15.6. No need to install macOS 26 just to use Xcode 26. At least for now. Though if you want to use the AI stuff in Xcode 26 you apparently do need macOS 26.
