iOS App Security

Use When

• Use when securing an iOS app — Keychain best practices with Secure Enclave, Data Protection classes for files, App Transport Security, certificate pinning via URLSession delegate, jailbreak detection, runtime tamper detection, binary protection (anti-debugging, anti-hooking), code signing and entitlements hygiene, and iOS 17+ privacy manifest. Complements ios-development (general standards), ios-stability-solutions (crash patterns), and ios-biometric-login (LocalAuthentication).
• The task needs reusable judgment, domain constraints, or a proven workflow rather than ad hoc advice.

Do Not Use When

• The task is unrelated to ios-app-security or would be better handled by a more specific companion skill.
• The request only needs a trivial answer and none of this skill's constraints or references materially help.

Required Inputs

• Gather relevant project context, constraints, and the concrete problem to solve; load references only as needed.
• Confirm the desired deliverable: design, code, review, migration plan, audit, or documentation.
