What version of Xcode runs on Big Sur?
What version of Xcode runs on Big Sur
AFAIK, it is Xcode 10 and over. I can run Xcode 10 GM (aka xCode 10.0) on MacOS BigSur 11.6.5; But Xcode 9.4 fails.
On macOS Monterey, Xcode 13 is required.
I found this document useful: "Minimum OS Required" for Xcode from https://developer.apple.com/support/xcode/. It's a matrix that details Xcode Version, Minimum OS Required, SDK, Swift version plus other info.
