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?

I’m currently facing a disk space limitation on my Mac. I’ve already freed up some storage by following the suggestions shared in a previous post, which helped partially, but the issue is not fully resolved and space is still a bottleneck for my workflow. To move forward, I’d like to ask a very concrete question: Is it safe and supported to move Xcode to an external hard drive (SSD), use it from there, and simply connect the drive whenever I need to work with Xcode? Specifically: Are there known issues with performance, stability, or updates? Are there components that must remain on the internal disk to avoid unexpected behavior? Is this a reasonable long-term setup, or just a temporary workaround? I want to make sure I’m not setting myself up for hidden problems down the road. Thanks in advance for any clarification or best practices you can share.

Hi everyone, I’m an iOS developer working on a Mac with limited storage (256 GB). I’ve noticed that the ~/Library/Developer folder is taking up almost 90 GB, mainly due to Xcode-related content. Inside it I see folders like: Xcode/DerivedData DocumentationCache iOS DeviceSupport UserData CoreSimulator/Devices Before deleting anything, I’d like to understand which of these folders are safe to clean up, and what the potential side effects might be (for example, rebuild times, simulator re-downloads, etc.). What is the recommended best practice to manage disk space when using Xcode on a low-storage machine? Thanks in advance for your help.

hy! apple developer community! No, I have a problem that's driving me crazy: Multiple commands produce '/Users/giulia/Library/Developer/Xcode/DerivedData/ScheduledStudy-dcmmhcdncitvfkdditbjoipfalqg/Build/Products/Debug-iphonesimulator/singintestwidgetExtension.appex/Info.plist'. Can you help me fix it? I know it's probably stupid, but I've been trying to fix it for days. There aren't two info.plist file, and that's why I don't quite understand. If you could help me, you'd be doing me a favor. Thanks for your time. P.S. I'm sorry, but I'm just starting out with programming and I'm also quite young.
