Recently when trying to create a new Vapor project, I encountered an error with my macOS Mojave installation. The installation went all fine with brew but when I ran vapor xcode, here is what I got:

$ vapor xcode
Generating Xcode Project [Failed]
error: terminated(72): xcrun --sdk macosx --find xctest output:
    
Error: Could not generate Xcode project: error: terminated(72): xcrun --sdk macosx --find xctest output:
    

I searched for solutions and found this post on Apple’s Developers Forum. Basically, the commands you need to run before running vapor xcode is:

sudo xcode-select --reset

That will reset the tools path to default and xcode project will generate!
