iOS device options (jailbreak, Corellium), pulling decrypted IPAs, class-dump, keychain inspection, URL schemes, pinning bypass.

iOS testing shares Frida with Android but the platform model, file layout, and toolchain differ enough to trip Android testers. This module walks through iOS-specific setup, keychain inspection, class-dump of Objective-C runtime, and SSL pinning bypass on an iPhone.

Device options in 2026

  • Jailbroken physical device — palera1n for A9–A11 chips on iOS 15/16, checkra1n for older. Newer hardware (A12+) has no reliable public jailbreak as of 2026
  • Corellium — commercial virtual iOS service. Runs real iOS in a browser-accessible VM. Used by many mobile pentest firms because it sidesteps the jailbreak availability problem
  • App sandbox testing — without jailbreak, you can still do limited testing via re-signing IPAs with your developer certificate and using iOS’s standard developer tools
