The easiest way to coexist your customized view and InAppMessaging default view.


There is only one step to start using SwiftyInAppMessaging.

func application(_ application: UIApplication, didFinishLaunchWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
  InAppMessaging.inAppMessaging().messageDisplayComponent = SwiftyInAppMessaging()


Define your message handler

struct InAppMyModalMessageHandler: InAppModalMessageHandler {
    let messageForDisplay: InAppMessagingModalDisplay
    let displayDelegate: InAppMessagingDisplayDelegate

    init?(message messageForDisplay: InAppMessagingDisplayMessage, displayDelegate: InAppMessagingDisplayDelegate) {
        guard let messageForDisplay = messageForDisplay as? InAppMessagingModalDisplay else {
            return nil

        self.messageForDisplay = messageForDisplay
        self.displayDelegate = displayDelegate

    static func canHandleMessage(message messageForDisplay: InAppMessagingDisplayMessage, displayDelegate: InAppMessagingDisplayDelegate) -> Bool {
        return messageForDisplay is InAppMessagingModalDisplay

    func displayMessage() {
        let alert = UIAlertController(title: self.messageForDisplay.title)
        let ok = UIAlertAction(title: "OK", style: .default, handler: { _ in })


        DispatchQueue.main.async {
            UIApplication.shared.topViewController?.present(alert, animated: true, completion: nil)

    func displayError(_ error: Error) {

Define your configuration

struct MyInAppMessagingConfiguration: SwiftyInAppMessagingConfiguration {
    let useDefaultHandlersIfNeeded: Bool = true
    let messageHandlers: [InAppMessageHandler.Type] = [

Pass handlers through configuration

func application(_ application: UIApplication, didFinishLaunchWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
  let config = MyInAppMessagingConfiguration()
  InAppMessaging.inAppMessaging().messageDisplayComponent = SwiftyInAppMessaging(with: config)
