Is deleting DerivedData safe?

Yes, it is safe as Xcode will regenerate these files; however, the skill prompts for confirmation because a full rebuild will be required afterward.

Can I reset all my simulators at once?

Yes, the skill provides commands to erase and reset all simulators simultaneously, allowing you to quickly return to a clean testing state.

How does this skill help with Xcode build errors?

It automates the removal of DerivedData and build caches, which are the primary causes of 'phantom' build errors and indexing issues in Xcode projects.

Does it handle Swift Package Manager dependencies?

Yes, it can clear local .build directories, remove Package.resolved, and purge global SPM caches to resolve dependency resolution problems.

Mobile Development

Optimizes iOS development workflows by managing build caches, DerivedData, and simulator environments.

This skill streamlines the iOS development process by providing automated routines for clearing Xcode build caches, removing project-specific or global DerivedData, and managing Swift Package Manager (SPM) dependencies. It also offers comprehensive simulator orchestration, allowing developers to boot, reset, and interact with iOS simulators—including app installation and screenshot capture—directly through Claude to resolve build instability and recover disk space.
