Hi everyone, I’m running out of space on my Mac and I need to use an external SSD to free up room, especially because Xcode is taking a lot of storage. I want to know if it’s safe to move some Xcode files—projects, derived data, or system-related files—to an external SSD. Which files can I move safely, and which should stay on the internal drive? I want to avoid breaking anything or causing issues with Xcode or macOS.

Also, is it the same situation if I use an external HDD instead of an SSD? Are there additional risks or performance issues to consider?

The only parts of Xcode that can't be moved to external storage are the parts that take up the bulk of your storage.

You haven't said anything about your storage (internal or external) or your development needs, so I can't provide any more detailed information.

In some cases, you can reduce Xcode's storage. You may be able to remove some or all of the simulator runtimes.

Generally speaking, this is one of those cases where you have to weight the cost of your time and trouble against the cost of a computer with more internal storage.
