Automating an iOS app build and launch in a simulator involves using xcodebuild to compile the app, then simctl to install and launch it on a dedicated simulator. This skill handles the full workflow automatically, deriving the target simulator from the git branch and validating its availability before building and testing.

Deterministic iOS simulator testing requires a repeatable workflow that reads the target simulator from the worktree state, validates its availability, and performs the build and launch sequence. This skill provides that consistent workflow, ensuring reliable build-and-run cycles across environments using xcodebuild and simctl.

Simulator cloning fallback activates when a required simulator is unavailable or missing. This skill recovers gracefully by cloning an existing simulator to meet the build-and-run requirements, allowing the xcodebuild and simctl workflow to continue without manual simulator creation or setup.

Deriving the target iOS simulator from a git branch or worktree state is supported automatically. This skill reads the worktree state, determines the appropriate simulator, validates its availability, and proceeds with the xcodebuild and launch sequence without requiring manual simulator selection.

Re-running an iOS simulator build after a failure involves following guidance to reset the deterministic workflow state. This skill provides recovery instructions to re-execute the xcodebuild, install, and launch sequence, ensuring the dedicated simulator is validated and ready before attempting the build again.
