Xcode Taking Too Much Storage (How to Free 50GB+)

How to fix it

Try these in order — the most common fix is first.

1. 1. Remove unused simulator runtimes

   Copy steps
   1. Xcode > Settings > Components
   2. Delete runtimes for platforms and versions you don't test
   3. Or list them: xcrun simctl runtime list and delete: xcrun simctl runtime delete <identifier>
   Did this fix it? Yes No

2. 2. Clean DerivedData

   Copy steps
   1. Quit Xcode
   2. Delete folders in ~/Library/Developer/Xcode/DerivedData (they rebuild automatically)
   Did this fix it? Yes No

3. 3. Delete unavailable simulators

   1. Run: xcrun simctl delete unavailable
   Did this fix it? Yes No

4. 4. Clear old device support and archives

   Copy steps
   1. Delete old folders in ~/Library/Developer/Xcode/iOS DeviceSupport
   2. Remove old builds in Xcode's Organizer > Archives you won't resubmit
   Did this fix it? Yes No

5. 5. Measure first

   Copy steps
   1. Check with: du -sh ~/Library/Developer/* and /Library/Developer/CoreSimulator
   2. Install only the platforms you actually target when you first set up Xcode
   Did this fix it? Yes No

Symptoms

Xcode and related folders use 50-150 GB, your Mac says storage is almost full, and 'Developer' shows a huge number in System Settings.

Why it happens

• Each iOS, watchOS, tvOS and visionOS runtime adds several GB
• DerivedData grows with every project
• Old iOS DeviceSupport and Archives pile up
• Simulator device data persists after runtime removal
