How to get the current selected Xcode and list installed

How to get the current selected Xcode and list installed

Current Selected Xcode

xcode-select

This is the most common way to get the path to the selected instance:

xcrun xcode-select --print-path

Multiple Xcode versions or Why xcrun is your friend


The story


I recently spent a few hours helping a friend of mine investigate a weird issue in their Continuous Development infrastructure. Builds were failing with different fatal errors mostly related to SDK paths and .platform directory locations. At first sight, it was clear that something is wrong with the current selected Xcode, but all our initial attempts to catch the problem failed.


In the end, we isolated the problem; one of the tools they use changes PATH silently for the environment to simplify access to Xcode tools. Due to their internal logic, the CD pipeline changes a current selected Xcode a few times on the way within the same script. In some cases, the pipeline ended with xcodebuild in the environment's PATH that does not reflect the expected version after the xcode-select --switch command.


How? Pretty easy, actually. A simplified sequence looked like this:

Xcode invocation tool - xed


xed is a command-line tool that launches the Xcode application and opens the given documents (xcodeproj, xcworkspace, etc.), or opens a new document, optionally with the contents of standard input.


If you work from the command line, this tool is a better option than open (which can open Xcode projects as well). Why?


    

  • xed knows about the current selected Xcode version (open behaves unpredictably if you have multiple Xcode installed)
    • 

  • You can use it open all files from a specific commit (with a little help explained below). It is useful on code-reviews or when you want to explore significant changes in the repository
    • 

  • You can use it as a "quick open" helper. Helps with monorepo phenomena, when you have hundreds of projects in the repository (I will show you an example below)
    •

                install Xcode from terminal
              
          

        

      

        

  

      

    
1. Download Xcode from https://developer.apple.com/download/more/ (this requeires to Login in with an Apple Developer Account)


At the moment id don´t know how to authenticate so i have no clue to download the xip via curl/wget.
In my case i downloaded the file and copied it via scp to my mac.

eg. for Xcode 9.2 https://developer.apple.com/services-account/download?path=/Developer_Tools/Xcode_9.2/Xcode_9.2.xip



2. Verify Signature of xip file


pkgutil --verbose --check-signature path/to/xip
