Xcode Junk iOS Device Support
Xcode iOS DeviceSupport stores files Xcode uses to work with specific iPhone and iPad iOS versions during development and device debugging.
What is Xcode Junk iOS Device Support?
This folder is part of Xcode’s developer data and contains iOS DeviceSupport files used when connecting physical iPhone or iPad devices to a Mac. Xcode may download or create these files so it can prepare devices, symbolicate crash logs, and support debugging for particular iOS versions. Developers commonly encounter this folder when Xcode has been used with one or more real iOS devices.

Safety overview
Status: Mostly safe
This is not a core macOS system folder, but it is used by Xcode for iOS development tasks. Removing its contents usually does not harm macOS itself, but Xcode may need to recreate or re-download support files later. If you still use Xcode with physical iOS devices, removing it can temporarily interrupt device support until the files are restored.
Recommendation: Keep this folder if you actively use Xcode with iPhone or iPad hardware, especially across multiple iOS versions. If you no longer do iOS development or do not connect physical devices, it is generally optional and can be removed, with the expectation that Xcode may recreate it later if needed.
