Xcode UI Previews 110GB: AI deletion judgment for Xcode storage
A practical first-pass checklist for Xcode UI Previews folder 110GB. The goal is to recover space without deleting the folder that proves expensive to rebuild.
Run the free Mac scan before deleting.
The Mac scan reads storage metadata locally, then shows the largest visible buckets and the files that need an AI delete / confirm / protect judgment.
Separate Xcode storage by risk bucket
Xcode storage is not one thing. DerivedData, Archives, simulator devices, simulator runtimes, DeviceSupport, and package caches have different recovery costs.
First read-only checks
Start with read-only folder sizes, then remove regenerable build data before touching archives or runtimes tied to active projects.
du -sh ~/Library/Developer/Xcode/DerivedData
du -sh ~/Library/Developer/Xcode/Archives
du -sh ~/Library/Developer/CoreSimulatorAI would usually mark delete
- DerivedData after Xcode is closed
- Old unavailable simulator devices
- Regenerable package and build caches
AI would mark confirm or protect
- Archives used for release symbolication
- Simulator runtimes required by current projects
- DeviceSupport folders for devices still being tested
Turn this into a deletion judgment
Start with the free SafeDisk Mac scan. If deletion risk is still unclear, send one request for the free SafeDisk AI deletion trial next step.
Still full after the SafeDisk Lite scan?
