Before running the open command I ran the following and I was able to use Xcode 13.2.1 in Venura. sudo xcode-select -s /Users/username/Downloads/Xcode.app

I have tried the most common suggestion of running it from command line but no luck. Command: open /Users/username/Downloads/Xcode.app/Contents/MacOS/Xcode Error: Xcode[3762:21719] [MT] IDEPackageInstallerHelper: Generic message for error: Error Domain=PKInstallErrorDomain Code=201 "An error occurred establishing a connection to the installation service." UserInfo={NSLocalizedDescription=An error occurred establishing a connection to the installation service.} I'm unable to download and install command line tools separately. It complains about the macOS version. I share the same sentiment as @zumacinsmity. On a regular day I support versions of the apps that are developed using older versions of Xcode. At least one major version older. In my case I was trying to install Xcode 13.2.1

@awsw please see https://developer.apple.com/library/archive/technotes/tn2339/_index.html#//apple_ref/doc/uid/DTS40014588-CH1-WHAT_KEYS_CAN_I_PASS_TO_THE_EXPORTOPTIONSPLIST_FLAG_. You need to create the plist manually.

I still see the problem in XCode 13.2.1. However, this only happens if I use the command line. Randomly fails with this error in pods. xcodebuild archive

Earlier I mentioned that @beruta's solution worked for me but it started failing again. What worked for me is cleaning Xcode project build files. "About This Mac" -> Storage -> Manage -> Developer This is also a neat way to clear up some space when you are running out.
