Lastly, as I was working on the Calendar+: App Blocker project and posted about it on Reddit, someone asked if there are ways to bypass the block and access apps by uninstalling the app.

As I was searching, I came across an interesting piece of code that can prevent your app from being uninstalled. However, it’s not just a single line of code—there are two steps you need to take before you can implement this:

1. Request Family Controls access from Apple.
2. Request Screen Time Control authorization from the user.

Once those steps are completed, you can add the following line of code to deny the app’s removal:

ManagedSettingsStore().application.denyAppRemoval = true

If the user tries to delete the app, it will look like this:

We use this option only when users enable our Deep Focus feature, to prevent them from uninstalling the app and bypassing the apps they have blocked.
