 Here are the commands that do it:
 
 ```bash
-xcodes install 15.3 # Or whatever version direnv tells you about
-xcodes runtimes install "iOS 17.4" # Or the latest iOS out there
+XCODE_VERSION="15.3" # Or whatever version direnv tells you about
+IOS_VERSION="17.4"
+xcodes install $XCODE_VERSION
+xcodes select $XCODE_VERSION
+xcodes runtimes install "iOS $IOS_VERSION"
 ```
 
 Xcodes install for the first time prompts you for Apple ID and Password. This is because Apple's license for XCode prohibits distribution of XCode from other servers than their own. And downloads from it can only work if you are authenticated. Hence, to use XCode, you need an Apple ID.
+Once the installs are done, you can `xcodes signout` to be on the safer side.
