Shipping an AI-Generated App to the App Store - Code Signing Is the Hard Part
Shipping an AI-Generated App to the App Store - Code Signing Is the Hard Part
Congratulations, you used AI to generate 80% of your macOS app. The UI works, the logic is sound, and you are feeling good. Now comes the part that no AI handles well - code signing, provisioning profiles, and the App Store submission dance.
The Last 20% Problem
AI coding tools are excellent at generating functional code. They can build SwiftUI views, implement data models, and wire up networking layers. But the moment you try to archive and distribute, you enter a world of certificates, provisioning profiles, entitlements, and App Store Connect configurations that are deeply stateful and environment-specific.
This is not a knowledge problem. It is a state problem. Your signing identity depends on your local keychain. Your provisioning profile depends on your Apple Developer account. Your entitlements need to match both your profile and your app's capabilities. AI cannot see any of this state.
What Actually Trips People Up
The most common failures are entitlement mismatches. Your app requests a capability - say, screen recording or accessibility access - but your provisioning profile does not include it. Or your profile includes it but your entitlements file does not declare it. The error messages from Xcode are cryptic at best.
Another classic is the "automatically manage signing" checkbox. It works great until it does not, and then you are manually configuring everything anyway with no understanding of what the automatic mode was doing.
How to Make It Work
Document your signing setup in CLAUDE.md. List your team ID, bundle identifier, distribution method, and required entitlements. When AI generates new features that need new capabilities, you will catch the entitlement gap early instead of at archive time.
Build an archive early in development - do not wait until the app is "done." The signing issues surface during archiving, and you want to find them before you have a deadline.
