In addition to directly downloading Xcode from the Appstore, you can also log in to the Developer Center [ https://developer.apple.com/download/ ] with your developer account to download the corresponding resources.
The advantage of downloading in the developer center is that the downloaded Xcode is an installation package that can be shared with other colleagues. In addition, the download address obtained when downloading can be copied to a third-party download tool to make the download speed faster. However, I think a more important reason is that you can download any historical version of Xcode .
Of course, it is sometimes beneficial to use the App Store to download. For example, the software update supports incremental updates , so in many cases, only a small incremental package needs to be downloaded to complete the update.
