simulator-management

Automating iOS simulator cleanup removes unavailable or duplicated simulators before tests run, stabilizing CI/CD pipelines. This skill coordinates pre-flight cleanup and boot-on-demand patterns using xcrun simctl commands to guarantee reproducible test environments and reduce manual maintenance.

Xcrun simctl manages the iOS simulator lifecycle through command-line operations for booting, shutting down, and deleting simulators. This skill enforces non-destructive defaults while providing patterns for pre-flight cleanup, boot-on-demand, and safe deletion to prevent race conditions in CI.

Yes, this simulator management approach integrates with Fastlane by letting CI tools manage boot and shutdown on demand. It coordinates the simulator lifecycle to avoid race conditions, allowing Fastlane to trigger automated boot and cleanup steps during the testing workflow.

The best way to handle duplicate iOS simulators is running a pre-flight cleanup that safely identifies and removes unavailable or duplicated devices. This skill provides patterns for recreating required simulators, ensuring reproducible results and clean test environments for Xcode-based projects.

iOS simulator test environments fail to reproduce results when unavailable or duplicated simulators cause race conditions during boot. This skill solves the problem by enforcing non-destructive defaults, automating pre-flight cleanup, and booting simulators on demand to stabilize CI runs.

Non-destructive defaults for iOS simulator management prevent accidental data loss but require explicit patterns for safe deletion and recreation. This skill relies on xcrun simctl commands, meaning it is limited to macOS environments running Xcode-based projects within CI/CD pipelines.
