## What is it?

When you connect an iPhone or iPad running a version of iOS or iPadOS that Xcode has not seen before, Xcode copies that version’s debug symbols to the Mac so it can debug and symbolicate on the device. Each version gets its own folder, named after the OS version and build (often with the device model), and old versions are never removed. Each folder typically takes a few gigabytes.

## What happens if you delete it?

If you connect a device running a version you removed, Xcode copies its symbols again, which takes a few minutes before debugging is available. Nothing else is lost.

## How to remove it properly

Quit Xcode, open `~/Library/Developer/Xcode/iOS DeviceSupport` with Finder’s Go › Go to Folder…, and move the folders for iOS versions you no longer debug on to the Trash. Keeping the newest folder avoids waiting for the copy the next time you plug in your current device.
