iOS apps from the App Store lack the get-task-allow entitlement required for debugger attachment. This technique documents the workflow for patching release builds to enable debugging.

Changes

  • Created MASTG-TECH-0140: iOS Patching technique

    • Overview of common patching scenarios (SSL pinning, debuggability)
    • Step-by-step workflow for adding get-task-allow entitlement via re-signing
    • Verification steps using codesign
    • Additional sections on binary patching and React Native apps
  • Updated MASTG-TECH-0091: References new technique for complete debuggable app workflow

Structure

Follows the modular approach of Android MASTG-TECH-0038:

## Patching Example: Making an App Debuggable

### Steps

1. Obtain development provisioning profile (@MASTG-TECH-0079)
2. Extract and verify current entitlements
3. Re-sign with development profile (@MASTG-TECH-0092)
4. Install and launch in debug mode (@MASTG-TECH-0055)
5. Attach debugger (@MASTG-TECH-0084)

### Verification

codesign -d --entitlements - "Payload/App.app"
# Should show: <key>get-task-allow</key><true/>

Cross-references existing techniques for obtaining provisioning profiles, signing, installing, and debugging rather than duplicating content.

title: Patching an App to Make it Debuggable

By default, app available on the Apple App Store are not debuggable. In order to debug an iOS application, it must have the get-task-allow entitlement enabled. This entitlement allows other processes (like a debugger) to attach to the app. Xcode doesn't add the get-task-allow entitlement in a distribution provisioning profile; it is only whitelisted and added in a development provisioning profile.

Please avoid repeating content as much as possible. As you can see in our techniques page we make our techniques very modular and narrow in scope so they can be easily reused across the guide.

Consider:

So I think this works well. You can write this new technique following a similar approach as in MASTG-TECH-0038: Patching (Android) where one of the sub-sections can be ## Patching Example: Making an App Debuggable.

Before submitting for review please validate that all the steps above work and you're able to debug the app as indicated in MASTG-TECH-0084: Debugging.

Please post here any proof (screenshots, etc.) and phone / OS versions and if it's jailbroken or not.

Thanks a lot!</comment_new>
