I have to crate a sample app in which when I clicked a button that should open the native alarm clock so that user can use it for setting alarm?
For default app MobileClock.app exists several url scheme. If u have a look in system files and open content for MobileClock.app u will find in info.plist private url scheme:
Which using them should be possible to run app externally but only from Today widgets. Also the same for the mobile notes app.
