Use xcrun simctl to free some disk space |
ios, xcode, command-line |
If you want to free some disk space by removing unused, unsupported or obsolete iOS simulator runtimes, you can first use the xcrun subcommand dedicated to managing simulators, simctl, to detect which runtime to delete:
xcrun simctl runtime list
The ouput will look like the following:
== Disk Images ==
-- iOS --
iOS 18.0 (22A3351) - 7976B5EC-52B8-4B7E-AF55-EC026BD24B51 (Ready)
iOS 17.5 (21F79) - 9591EEC3-598B-48AC-986D-53CEAB6FEBDB (Ready)
iOS 15.4 (19E240) - 5E844228-D8DF-4662-8D0E-9F3D1B898FAC (Ready)
iOS 16.4 (20E247) - 2671D0D4-24FF-4DAB-B148-C6C3547621E2 (Ready)
-- tvOS --
tvOS 18.0 (22J356) - F9F3744E-EDB7-4849-AFAB-21F103AA404A (Ready)
-- xrOS --
xrOS 2.0 (22N318) - A3675326-E2E5-4CEA-B0C9-68930F3E3317 (Ready)
Total Disk Images: 6 (32.1G)
Once you've decided which runtime has to go, you can use the delete <identifier> subcommand.
For instance, when your app stops supporting iOS 15, you can remove its simulator runtime with :
xcrun simctl runtime delete 19E240
You can even use the all alias to delete all images :
xcrun simctl runtime delete all
or add an option to only delete images not used within the past <days> days :
xcrun simctl runtime delete --notUsedSinceDays 365
Finally, you can test your command before actually executing it, by appending --dry-run.
Thus, typing this command:
xcrun simctl runtime delete all --dry-run
would provide that output:
