Use PermissionScope in Swift

When we are building the application and we need permission so something we need to fetch contacts, notifications, and camera.Its better approach to take permission on starting of the application rather than again it says for permission.You can use PermissionScope to implement this feature. How to use PermissionScope library:-

• Install pods pod ‘PermissionScope’
• import PermissionScope
• Create an object of  PermissionScope
  
  1	let permissionScope = PermissionScope()

• Set up permissions which you need and maximum 3 permissions you can add one time
  
  1 2 3 4 5 6 7 8 9 10 11

  // Set up permissions   permissionScope.addPermission(LocationWhileInUsePermission(),                                 message: "We use this to track\r\nwhere you live" ) permissionScope.addPermission(NotificationsPermission(notificationCategories: nil),                                 message: "So that we can send you the latests updates straightaway" ) permissionScope.addPermission(PhotosPermission(),                                 message: "So that we can access to your Photos from Camera roll" )

• Show permission dialog with callbacks
  
  1 2 3 4 5 6 7 8 9 10 11 12

  // Show permission dialog with callbacks permissionScope.show(     { finished, results in         print("Permissions state changed, results: \(results)")                   },     cancelled: { results in         print("User closed the permission alert, results: \(results)")     } )

  
   
• You can also check that permission are authorized or not before and after the PermissionScope
  
  1 2 3 4 5

  if PermissionScope().statusLocationInUse() == .authorized {    print("authorized") }

• Main advantage of this library is that if user denied permissions you can click on DENIED button, then it will take you in settings of  iPhone here you can change permissions of  your application
