feat(ios): honor networkingOptions.enableLogging via Auth0.swift logging

[subhankarmaiti]

networkingOptions.enableLogging was previously Android-only and silently ignored on iOS. This wires it into the iOS native bridge so it now enables Auth0.swift's HTTP request/response tracing on iOS too.

On iOS the flag maps to Auth0.swift's .logging(enabled:), which traces to the unified logging system (OSLog, category NetworkTracing) with access, refresh, and ID tokens redacted. It's applied to every native builder — web auth, logout, authentication, MFA, My Account, and passwordless. As on Android, enable it only while debugging.

const auth0 = new Auth0({
  domain: 'YOUR_DOMAIN',
  clientId: 'YOUR_CLIENT_ID',
  networkingOptions: { enableLogging: true },
});

Verified locally on both platforms: with the flag on, the /oauth/token exchange is traced (redacted on iOS, plaintext on Android); with it off, nothing is logged.

📝 Summary

Summary by CodeRabbit

• New Features

  • Enabled enableLogging for authentication, passwordless, MFA, and token-related operations on iOS.
  • iOS request and response logging uses OSLog with sensitive tokens redacted.

• Documentation

  • Clarified that timeout and header settings apply only on Android.
  • Documented that logging is supported on both platforms.
  • Described Android debug-only logging, including plaintext request and response bodies, with logging disabled in release builds.
  • Documented iOS token redaction and OSLog behavior.

Walkthrough

The PR enables iOS enableLogging handling during Auth0 initialization. It propagates the setting to native clients and applies Auth0.swift logging across authentication, web authentication, MFA, account, passwordless, passkey, and token exchange flows. Documentation now describes platform-specific behavior.

Changes

Networking logging

Layer / File(s)	Summary
Platform logging contract EXAMPLES.md, src/platforms/native/bridge/NativeBridge.ts, src/types/common.ts	Documentation separates Android-only timeout and header behavior from enableLogging behavior on Android and iOS.
iOS logging initialization ios/A0Auth0.mm, ios/NativeBridge.swift, ios/A0MfaClient.swift, ios/MyAccount.swift, ios/Passwordless.swift	iOS initialization reads enableLogging, stores it in NativeBridge, and passes it to MFA, account, and passwordless clients.
Client logging paths ios/NativeBridge.swift, ios/MyAccount.swift, ios/Passwordless.swift	Configured logging is applied to account, passwordless, authentication, web authentication, passkey, token exchange, and logout clients.

Merge Risk: 🟠 High · up to b0452

Opting into iOS networking logging can write access, refresh, MFA, OTP, or password values to OSLog, creating a serious sensitive-data exposure that should be fixed before merging.

In `@ios/MyAccount.swift`:
- Line 24: Disable request logging for the credential-bearing clients, including
My Account, Passwordless, credential manager/authentication, custom-token
exchange, passkey exchange, and MFA clients. Update each corresponding client
configuration using logging(enabled:) so request headers and raw request bodies
cannot expose credentials; if logging must remain enabled, add request-header
and request-body redaction at every listed site.
