trying to reinstall xcode. Keep getting told not enough space even though there is (I think?)

Title says it all. So from what I can tell there is enough disk space.

I have attempted to get it from the app store and just a straight up download. App store says not enough space, when I try to expand the .xip file download it says not enough space. I can’t for the life of me figure out what I need to do since there should be more than enough space for 10 – 11 GB.

Running df seems to show there is enough space (unless I am not understanding this

Can anyone explain to me what I need to do to download this and get it running again? I guess it is either, find out how much more space I need and clear it out (really just how to determine how much more space I need, what "space" is the issue) or what process I can take to get it running.

    You do not have enough free space to install Xcode. The 10-11 GB file you are downloading is a compressed file. The expanded file is larger than the 17 GB of free space you have. The operating system temporarily needs space to hold both the compressed and expanded versions. You need 4-5 times the size of the Xcode download file to install Xcode. That is going to be tough to do on a 128 GB drive.

    The best solution for you is to download Xcode from Apple’s developer download site on an external drive. Expand the file on the external drive and copy it to your main drive. By doing this, you don’t need as much free space available on the main drive.

    Some things you can do to free up disk space on your main drive include:

    • Delete any existing versions of Xcode.
    • Use the DevCleaner app to clean out any caches and old simulators.
    • Restart your Mac.

    In my opinion, this is the easiest and fastest solution to free up enough space to install a new version of Xcode.
    Here are a few steps to free up disk space if you’ve already used Xcode:

    • Go to About This Mac
    • Then go to Storage
    • Then go to Manage…
    • Go to Developer
    • Delete project build caches or some unused SDKs that you no longer use

    I will also put screenshots so you can found more easily and see how much memory they take up this unused SDKs.

    Here’s the trick:

    • Create a huge file (~20GB).
    • Then delete it (don’t forget to clean up
      the trash).
    • Unpack Xcode.xip.

    To create a very big file you can use mkfile (very slow) or dd.
    Below is a terminal command that creates the temp_20GB_file file with random data:

    dd if=/dev/urandom of=temp_20GB_file bs=1024 count=$[1024 * 1024 * 20]
