iOS DeviceSupport
iOS DeviceSupport stores Xcode device support files and symbols used when connecting, debugging, and symbolicating logs from iPhone and iPad devices.
What is iOS DeviceSupport?
iOS DeviceSupport is a folder used by Xcode to store support files for physical iPhone and iPad devices. These files help Xcode communicate with connected hardware, run and debug apps on device, and symbolicate crash logs with the correct system symbols. The folder is created and updated as you connect devices with different iOS or iPadOS versions, so it can grow over time on development Macs. People who build, test, or troubleshoot Apple-platform apps commonly encounter it in the Library > Developer area. It is part of the normal Xcode workflow rather than a standalone app, and its contents are tied to device support and debugging tasks.

Safety overview
Status: Mostly safe
This folder is normal developer data created by Xcode. Removing old contents is generally low risk if you no longer debug or symbolicate logs for those device versions, but deleting active support files can interrupt on-device debugging and reduce Xcode's ability to symbolicate crash reports until the files are downloaded or copied again. Treat it as rebuildable developer data, not personal content.
Recommendation: Keep this folder if you use Xcode with physical iPhone or iPad devices, need device logs, or troubleshoot crashes. If you no longer do on-device development, you can remove older version folders to recover space. Xcode may recreate needed files the next time you connect a device or work with that OS version.
