SwiftUI Showing Specific Landmarks on Opening the map - swift

Question

I was wondering to see if there is a way to show the nearest specific landmarks[ie railway stations] just to see where the user can go to? I am trying to also show the point to point of landmarks but should revolve first around the user. top 3 nearest landmarks should do, please any help or resources?
