How do I determine which iOS SDK I have?

Question

I\'m sure this is simple, but how do I determine which version of the iOS SDK I currently have installed?

Answer 1

The simplest why I found is to run this command line:

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

OR, if you have multiple XCode versions:

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

fastlane isn't able to successfully execute that command so it sounds like that you don't have an Xcode version selected for xcodebuild to run things with. Running the xcode-select command above should do the trick for you ;)
