Is it possible with this kind of App request?

im a bit new to Swift but have tryed to figure it out without luck.

Problem:

  • Eatch account/user-profile in the App should get a unique number
  • i want a profile to be able to “send a request” typing in the number of the other profile they want to send the request to and then the other profile get a ping saying that he/she needs to press accept and write in the login password before the request gets accepted and both profiles get up on the screen or like in a “logg-file” that both persons have accepted the transfer.

is this even possible in a swift IOS App or do i have too go for a “friend request” solution?

Sorry for my Englsih, hope you guys understand me, Thanks for your time!
