@mmewh macOS Sonoma 14.6, same error : Error: Your Xcode (15.1) is outdated. MacBook Pro M3. Tried to build as specified in the readme included with the toolkit 2.0 beta. They specifically said to install Xcode 15.1 & CLT 15.1 This is highly unfortunate, hope they fix it soon

@mmewh Same!!! Spent an hour compiling with Xcode 15.1 & CLT 15.1 only to get a message: "hey, your Xcode is outdated" *facepalm From the readme included with the GPTK 2.0 beta: 1. Setup your development and Homebrew environment • Ensure that you are usihg Command Line Tools for Xcode 15.1. Visit https://developer.apple.com/downloads to download this older version of the tools. Note: there is a header file layout change preventing the use of newer versions of the macOS SDK which we are well aware of. Haha, "well aware of" Why even publish this stuff if it is unbuildable in its current state? Shocking incompetence, unexpected from Apple (although.... Xcode is probably the saddest apple product)
