 to do this is in your `AppDelegate`
 
 ```swift

-    Compass.scheme = "compass"

 #### Step 3
 Configure your application routes
 
 ```swift
-func application(application: UIApplication,
-  didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
-    Compass.scheme = "compass"
-    Compass.routes = ["profile:{username}", "login:{username}", "logout"]

+  return true
 }
 ```
 #### Step 4
 Set up your application to respond to the URLs, this can be done in the `AppDelegate` but its up to you to find a more suitable place for it depending on the size of your implementation.
 
 ```swift
-func application(app: UIApplication,
-  openURL url: NSURL,
-  options: [String : AnyObject]) -> Bool {
-    guard let location = Compass.parse(url) else {
-      return false

+func application(_ app: UIApplication,
+                 open url: URL,
+                 options: [UIApplicationOpenURLOptionsKey : Any]) -> Bool {
+  guard let location = Compass.parse(url) else {
+    return false
+  }
 
-    let arguments = location.arguments

-    switch location.path {
-      case "profile:{username}":
