Xcode – Can you somehow restrict any installed app with your own app?

Basically I want to create an app where you can select any of your installed apps and then restrict/unrestrict them. I have a great idea for an app, but need the user to be able to restrict an installed app with my own app for it to work.

I tried working with screen time restrictions but couldn’t get it to work somehow. Im doing this on IOS 17 Xcode. Also im pretty new to programming so I dont know a lot of stuff. I especially lack a lot of knowledge in screen time of iOS 17.

    1. I’m afraid Apple does not provide API to get any installed apps (by security reasons)
    2. For implementing the application restrict/unrestrict you need to build your own VPN. I can suggest checkout UI/UX for an application like "Freedoom" – they just predict what app to allow and what app to restrict (using their own VPN)
    3. Apple gets this statistic about usage by using their private API, but they can share this data with you. I can suggest to check out this WWDC video What’s new in Screen Time API

    Apple does provide a mechanism where a limited number of apps can exclusively share information amongst themselves: "App Groups".

    https://developer.apple.com/documentation/bundleresources/entitlements/com_apple_security_application-groups

    Using this, they can pass information to each other via UserDefaults

    https://developer.apple.com/documentation/foundation/userdefaults/1409957-init

    or shared files via "shared containers".

    With this, it seems like you could make these related apps set and read some limitations via config file.
