SimCleaner now cleans up Xcode caches as well as simulators. • Smart Cleanup removes, in one click, what Xcode rebuilds on its own and you haven't used for the period you pick (7, 14, 30 or 90 days): DerivedData of projects you haven't opened, device support files for iOS versions your devices have moved on from, simulators Xcode made for SwiftUI Previews and tests, and build folders that coding agents leave behind. Each item is checked again right before it goes, and anything used in the meantime stays. • A bar at the bottom of every page shows how much space simulators, runtimes, DerivedData, device support files and caches take, next to your free space. Click a part of the bar to jump to its page. • A "Freed about" total adds up your cleanups. • Xcode caches have their own page, with DerivedData listed per project. • A Runtimes page shows how much space each runtime takes and how many simulators use it. • Erase, shut down, duplicate and rename simulators. Every change goes through Xcode's own simctl, so Xcode sees it right away. • Install one build on several running simulators at once. • Search by the name of an installed app, and open an app's Documents, Caches or Preferences folder in Finder. • Help > Send Feedback opens an email to the developer with your app and macOS versions filled in.
