+#### If your AppDelegate is in swift
+If your `AppDelegate` is in `swift` and you are using react native version greater than or equal to 0.78, then your AppDelegate.swift has to implement the protocol `HyperSdkReactDelegate` and return the `reactNativeFactory` property from the `getReactNativeFactory` function. This helps us to render your view(Merchant View) in our payment page.
+
+```swift
+  ...
+  import hyper_sdk_react
+
+  @main
+  class AppDelegate: UIResponder, UIApplicationDelegate, HyperSdkReactDelegate {
+    ...
+    var reactNativeFactory: RCTReactNativeFactory?
+    ...
+    
+    func getReactNativeFactory() -> Any! {
+      return reactNativeFactory
+    }
+  }
