App installation failed due to application-identifier entitlement



📱🚫 App Installation Failed? Don't Sweat It! 😅💪
You're ready to dive into the exciting world of watchOS 2 WatchKit apps, but you hit a roadblock 🛑 - your app won't install because of an application-identifier entitlement issue. Don't worry, we're here to help you troubleshoot this common problem and get your app up and running in no time! Let's dive in! 🏊♀️
🧐 What's the Problem?
The error message you encountered is quite explicit: "App installation failed. This application's application-identifier entitlement does not match that of the installed application. These values must match for an upgrade to be allowed." 😱
So, what caused this error? In your case, you mentioned that it happened after you turned on App Groups in the Capabilities tab. Fortunately, this gives us a clue to focus on. 👀
💡 The Solution: Easy Peasy! 😎
To fix this issue, follow these steps:
Open your Xcode project and navigate to the Capabilities tab.
Locate and disable the App Groups capability.
Clean your project by navigating to Product ➡️ Clean Build Folder.
Run your application again.
✅ Verifying the Fix
After following the above steps, your app should install without any hitch. However, if the error persists, don't despair! Sometimes, removing the entitlements files alone may not be sufficient. In such cases, try the following additional steps:
Double-check that you disabled the App Groups capability correctly.
Remove the entitlements files once again, being extra careful not to miss any.
Perform a clean build by navigating to Product ➡️ Clean Build Folder.
Now, try running your application once more.
By rechecking the App Groups capability and going through the cleanup process, you'll maximize your chances of success! 💪🍀
