Is Xcode iOS DeviceSupport Safe to Delete?
Yes. These are symbol files for iPhones and iPads you plugged in. Xcode copies them again when you connect the device.
Side effects: The next debug session on that device will wait while Xcode recopies symbols (several GB).
What is ~/Library/Developer/Xcode/iOS DeviceSupport?
Each iOS version/device combo stores DWARF symbols under DeviceSupport. They are safe to delete and are a common reason ~/Library/Developer looks huge even after clearing DerivedData.
Is it safe to delete?
Yes — ~/Library/Developer/Xcode/iOS DeviceSupport is generally safe to delete. The data in this folder is temporary and will be recreated by the application when needed.
Before deleting, make sure:
- You don't have any important unsaved work in the related application
- You're not in the middle of a critical task that might need this cached data
- You understand that initial load times may be slower after deletion
What happens after deletion?
The next debug session on that device will wait while Xcode recopies symbols (several GB). The folder will be recreated automatically by the application when needed. This process is typically seamless but may take some time depending on the amount of data that needs to be regenerated.
