Resolving the ‘App Installation Failed’ Error Due to Application-Identifier Entitlement

28 February 2025 Stephan Petzl Leave a comment Xcode

Encountering the “App installation failed” error when dealing with application-identifier entitlements can be a frustrating experience, especially when deploying a watchOS 2 WatchKit app. This error typically arises when there is a mismatch between the application-identifier entitlement of the app you are trying to install and the one already present on the device. This guide provides a straightforward solution to tackle this issue effectively.

Understanding the Issue

The error message indicates that the application’s application-identifier entitlement does not match the installed application’s entitlement. This mismatch prevents the app from being upgraded or installed on the device, often after making changes such as enabling App Groups or modifying the provisioning profile.

Step-by-Step Solution

1. Connect your device to your computer and open Xcode.
2. Select Window → Devices from the menu.
3. In the Devices window, select your device from the left panel.
4. Locate the problematic app in the “Installed Apps” list in the right panel.
5. Remove the app from the list by clicking the gear icon and selecting “Remove”.

After completing these steps, rebuild and launch your app from Xcode. This process should resolve the issue and allow the app to run smoothly on your device.

Preserving Data During Reinstallation

If you need to preserve existing test data, follow these additional steps before removing the app:

• Open the Xcode “Devices” window (Cmd + Shift + 2).
• Select your device and find your app in the “Installed Apps” list.
• Click the gear icon and choose “Download Container…” to back up the app’s data to your Mac.
• After reinstalling the app, use “Replace Container…” to restore the saved data.

This ensures that your test data is preserved, allowing you to continue testing without data loss.
