Pressure Testing Validated under App Store deadline pressure, authority pressure, misinterpretation scenarios
Research-Validated WWDC 2025 skills (Liquid Glass, SwiftUI Performance, UI Testing) reviewed against official guidance
Peer-Reviewed Reference skills (persistence) reviewed for accuracy and completeness

Key Metrics

Reduces debugging time 30+ min → 2-5 min (Xcode issues)
Memory leak diagnosis 2-3 hours → 15-30 min
Test reliability From flaky (50% CI failures) → reliable
Performance Systematic optimization vs. guessing
