  • UI Testing – Recording UI Automation (Xcode 26) and condition-based waiting

Debugging & Troubleshooting ​

Systematic debugging strategies to solve issues faster and prevent common problems before they happen.

Concurrency & Async ​

Master Swift's concurrency model and catch data races at compile time with strict concurrency patterns.

Persistence ​

Comprehensive database patterns for safe schema evolution and choosing the right persistence framework.

  • Database Migration – Safe schema evolution for SQLite/GRDB/SwiftData

Skill Development Methodology ​

Skills in Axiom are developed using rigorous quality standards:

TDD-Tested Skills ​

Battle-tested against real-world scenarios and pressure conditions:

  • xcode-debugging – Handles mysterious build failures, zombie processes, and simulator hangs
  • swift-concurrency – Prevents data races and actor isolation errors in Swift 6
  • database-migration – Prevents data loss during schema changes with 100k+ users
  • swiftdata – Handles CloudKit corruption, many-to-many relationships, and unfollow patterns
  • memory-debugging – Finds PhotoKit leaks and diagnoses non-reproducible memory issues
  • ui-testing – Handles flaky tests, network conditions, and App Store review blockers
  • build-troubleshooting – Resolves dependency conflicts under production crisis pressure
  • liquid-glass – Navigates design review pressure and variant decision conflicts
  • swiftui-performance – Diagnoses performance issues under App Store deadline pressure
  • swiftui-debugging – Solves intermittent view updates and preview crashes
  • performance-profiling – Identifies CPU bottlenecks, memory growth, and N+1 queries
  • sqlitedata – Handles StructuredQueries migration crashes and data-loss scenarios
  • grdb – Optimizes complex join queries and ValueObservation performance

Reference Skills ​

All reference skills are reviewed against 4 quality criteria:

  1. Accuracy – Every claim cited to official sources, code tested
  2. Completeness – 80%+ coverage, edge cases documented, troubleshooting sections
  3. Clarity – Examples first, scannable structure, jargon defined
  4. Practical Value – Copy-paste ready, expert checklists, real-world impact
