Have enough free disk space that is at least 5 times the size of the compressed Xcode file you are going to download from Apple. If an alert opens saying you don’t have enough space to install Xcode, you don’t. Xcode releases keep getting larger over time so the amount of free disk space you need will increase as well.

That may not be enough free space, especially for newer Xcode versions.

Add in some temporary storage space for swapping files, and you need a minimum of 30 GB of disk space to install Xcode.ģ0 GB of disk space is just an example. At this point you need 25.39 GB of free space. Xcode 11.4.1 takes up 17.39 GB on my Mac. The expanded file is going to be bigger than that. You need enough disk space to store both the compressed file you downloaded and the expanded file. The Xcode file that you download is a compressed file.

You Need More Free Space Than the Download Size Usually the person asking the question has 15–20 GB of free space on their startup disk.

These people always say they have enough space because they have more free space on their disk than the Xcode download. People constantly post on Apple’s developer forums complaining that when they try to install Xcode, an alert opens saying they don’t have enough disk space to install it.
