The Command Line Tools Package is a small self-contained package available for download separately from Xcode and that allows you to do command line development in macOS. Once you have it extracted, you can delete the. As you can tell, the download is over 7GB and will require more than 23GB of space to extract. Then click on View Details for the version you’d like (14.2 in this example) and finally click on the download link which will have the extension. Once you have your account, you can see all the Xcode downloads from the Apple Developer website: If you’d like to read up on the differences between the two account type, you can check out Apple’s support article “ Choosing a Membership”.

One is a free account and the other is $99/year which includes the ability to publicly distribute your iOS/macOS apps. There are now two types of accounts you can use to sign into the Apple Developer website. You can also download current and older versions of Xcode from the Apple Developer website but first you will need a developer account. After that point, you can then click OPEN or in the future run it like any other application (Spotlight Search, Finder -> Applications, etc). The Mac App Store will handle downloading Xcode and installing it on your system. If you don’t have an Apple ID, you can easily create your Apple ID with any existing email address.
