Introduction

This signing error means the app identifier inside your built entitlements does not match the app identifier allowed by the selected provisioning profile. In practice, the mismatch is usually between the Team ID plus bundle identifier in Xcode and the values embedded in the provisioning profile.

What the Error Really Means

Apple signing ties together several values:

• your Team ID
• the bundle identifier in the target settings
• the application-identifier entitlement
• the selected provisioning profile

The effective application identifier normally looks like TEAMID.bundle.identifier. If the entitlements file or generated entitlements say one thing and the profile allows another, signing fails.

A typical mismatch looks like this:

• target bundle ID is com.example.myapp
• profile was created for com.example.otherapp
• entitlements resolve to ABCDE12345.com.example.myapp
• profile only allows ABCDE12345.com.example.otherapp

That is enough to trigger the error even if the project builds fine otherwise.

Check Xcode Signing Settings First

Start with the target in Xcode:

• confirm the selected Team
• confirm the Bundle Identifier
• check whether signing is automatic or manual
• confirm the provisioning profile belongs to the same app ID

If you use automatic signing, the quickest fix is often to let Xcode regenerate the profile after you correct the bundle identifier.

If you use manual signing, verify that the profile was created for the exact same app ID, not a different explicit ID and not a wildcard profile that lacks the capabilities you are using.

Inspect the Built Entitlements and Profile

When the UI is unclear, inspect the actual files. You can dump the entitlements from the built app:

codesign -d --entitlements :- /path/to/MyApp.app

You can also inspect a provisioning profile:

security cms -D -i /path/to/profile.mobileprovision > profile.plist
plutil -p profile.plist

Compare:

• the application-identifier
• the com.apple.developer.team-identifier
• the entitlements required by capabilities such as push notifications or iCloud

Those commands usually expose the mismatch faster than clicking through build settings repeatedly.

Bundle ID Changes Often Cause It

This error commonly appears after renaming the app or changing the bundle identifier. The project may now request:

ABCDE12345.com.example.newname

while the old provisioning profile still allows:

ABCDE12345.com.example.oldname

The fix is not to edit the generated entitlement blindly. The fix is to align the bundle ID, profile, and capabilities so Xcode generates matching values.

Capability Mismatches Can Also Trigger It

Even when the bundle identifier looks correct, the profile may still be wrong if it was created before enabling a capability such as:

• Associated Domains
• Push Notifications
• iCloud
• App Groups

In that case, regenerate the provisioning profile after enabling the capability in the Apple Developer portal and in Xcode.

A Clean Recovery Path

When the signing configuration is messy, the fastest path is often:

1. remove old manual profile selections in Xcode
2. confirm the correct Team and Bundle Identifier
3. clean the build folder
4. enable automatic signing temporarily
5. let Xcode fetch or create a matching profile

If you must stay on manual signing, download a fresh profile that matches the current app ID and install it explicitly.

Common Pitfalls

The most common mistake is editing the entitlements file directly while leaving the provisioning profile and bundle identifier inconsistent. The error is usually about mismatched signing inputs, not about needing a hand-written entitlement tweak.

Another issue is using a profile from the wrong team. The bundle identifier may look correct, but a different Team ID still breaks the application-identifier.

Wildcard profiles also confuse people. They can work for simple apps, but once certain capabilities are involved, you often need an explicit app ID and a matching explicit profile.

Finally, stale cached profiles in Xcode can keep the problem alive after you already fixed the portal settings. Removing outdated profiles and re-downloading the correct one can save time.

Summary

• The application-identifier in the built entitlements must match the provisioning profile.
• Check Team ID, Bundle Identifier, and profile selection together.
• Inspect the built app entitlements and provisioning profile if Xcode is unclear.
• Regenerate the profile after changing bundle IDs or capabilities.
• Prefer fixing the signing configuration over hand-editing generated entitlements.
