I want to open an app which user chose from FamilyActivityPicker. What i know is that ios needs url scheme when open another app in an app, and familyActivityPicker can give me some application info. for example, i can get selected app's title and icon through Label(:ApplicationToken). Can I get url schemes similar to this way?
No, you can't get that information from an ApplicationToken or through the Family Controls or Managed Settings frameworks. The only workaround I can think of is to find a way to ask your user to identify the ApplicationToken he or she just selected through the FamilyActivityPicker. If your user says he or she selected TikTok for example, you can "easily" find the matching url scheme － you will have to build your own custom list for those though.
