Networking Audit

Quick automated scan to identify deprecated networking APIs and anti-patterns in your Swift/Objective-C codebase.

What It Scans

Deprecated APIs

Pattern	Risk	Replacement
SCNetworkReachability	Race condition	NWConnection waiting state
CFSocket	Missing features	NWConnection
NSStream, CFStream	Complex, error-prone	NWConnection
NSNetService	Missing benefits	NWBrowser
getaddrinfo()	Blocking operation	NWConnection (automatic)

Anti-Patterns

Pattern	Risk	Fix
Reachability check before connect	Race condition	Use waitsForConnectivity
Hardcoded IP addresses	Proxy/VPN issues	Use hostnames
Missing [weak self] in callbacks	Memory leaks	Add capture list
Blocking socket calls	ANR/crashes	Use async APIs
Not handling waiting state	Poor offline UX	Monitor state changes

Usage

# Scan entire project
/axiom:audit networking

# Scan specific directory
/axiom:audit networking Sources/Networking/

Example Output

=== NETWORKING AUDIT RESULTS ===

DEPRECATED APIs (3 issues):
  NetworkManager.swift:45 — SCNetworkReachability
    → Replace with NWConnection waiting state

  LegacySocket.m:120 — CFSocket
    → Migrate to NWConnection

ANTI-PATTERNS (2 issues):
  Config.swift:15 — Hardcoded IP "192.168.1.1"
    → Use hostname for proxy/VPN compatibility

  ConnectionManager.swift:67 — Missing [weak self]
    → Add capture list to prevent retain cycle

POSITIVE PATTERNS (found):
  ✓ NWConnection: 5 files
  ✓ URLSession: 12 files

Time Estimates

• Replace SCNetworkReachability: 5-10 min
• Add [weak self]: 1-2 min
• Replace hardcoded IP: 2-5 min
• Migrate from CFSocket: 30-60 min
