Everyone working with Apple Xcode probably knows that it requires a considerable amount of disk space. Especially when you update to newer versions, it keeps a lot of stuff around which is just taking up disk space.
Until today, I always used the app Dev Cleaner to clean this up, but I learned there is another way to do so, built-in into macOS Big Sur.
If you go to the Apple icon in the menu bar, you can select "About this Mac". There, you can go to "Storage" and choose "Manage…". If you then select "Developer" in the left column, you get a view like this:
Tada, a built-in tool to clean it up.
