Display flows & paywalls - iOS

Display flows and paywalls
Flows BETA Built in Flow builder — renders natively on device, no WebView
Paywall Builder paywalls All existing Paywall Builder content

If you’ve created a flow or paywall, you don’t need to worry about rendering it in your mobile app code to display it to the user. Such a flow or paywall contains both what should be shown within it and how it should be shown.

To get the AdaptyUI.FlowConfiguration object used below, see Get flows and paywalls.

Present flows and paywalls in SwiftUI

Present as a modal view

In order to display a flow or paywall on the device screen as a modal view, use the .flow modifier in SwiftUI. The minimal call requires isPresented, flowConfiguration, and the four required callbacks:

.flow(
    isPresented: $flowPresented,
    flowConfiguration: <AdaptyUI.FlowConfiguration>,
    didFailPurchase: { _, _ in /* handle the error */ },
    didFinishRestore: { _ in /* check access level and dismiss */ },
    didFailRestore: { _ in /* handle the error */ },
    didReceiveError: { _ in flowPresented = false }
)

For more control, add optional callbacks like didPerformAction to handle button taps and didFinishPurchase to react to successful purchases:

@State var flowPresented = false // ensure that you manage this variable state and set it to `true` at the moment you want to show the flow or paywall

var body: some View {
  Text("Hello, AdaptyUI!")
      .flow(
          isPresented: $flowPresented,
          flowConfiguration: <AdaptyUI.FlowConfiguration>,
          didPerformAction: { action in
              switch action {
                  case .close:
                      flowPresented = false
                  default:
                      // Handle other actions
                      break
              }
          },
          didFailPurchase: { product, error in /* handle the error */ },
          didFinishRestore: { profile in /* check access level and dismiss */ },
          didFailRestore: { error in /* handle the error */ },
          didReceiveError: { error in flowPresented = false }
      )
}

Parameters:

ParameterRequiredDescription
isPresentedrequiredA binding that manages whether the flow or paywall screen is displayed.
flowConfigurationrequiredAn AdaptyUI.FlowConfiguration object containing visual details of the flow or paywall. Use the AdaptyUI.getFlowConfiguration(forFlow:) method. Refer to Get flows and paywalls for more details.
didFailPurchaserequiredInvoked when Adapty.makePurchase() fails.
didFinishRestorerequiredInvoked when Adapty.restorePurchases() completes successfully.
didFailRestorerequiredInvoked when Adapty.restorePurchases() fails.
didReceiveErrorrequiredInvoked for a rendering error or a runtime error from the flow script (for example, a JavaScript exception, AdaptyUIError code 4105). For rendering errors, contact Adapty Support.
fullScreenoptionalDetermines if the flow or paywall appears in full-screen mode or as a sheet. Defaults to true.
didAppearoptionalInvoked when the flow or paywall view was presented.
didDisappearoptionalInvoked when the flow or paywall view was dismissed.
didPerformActionoptionalInvoked when a user clicks a button. Two action IDs are pre-defined: close and openURL; others are custom and can be set in the builder.
didSelectProductoptionalInvoked when a product is selected for purchase by the user or by the system.
didStartPurchaseoptionalInvoked when the user begins the purchase process.
didFinishPurchaseoptionalInvoked when Adapty.makePurchase() completes successfully.
didFinishWebPaymentNavigationoptionalInvoked when web payment navigation finishes.
didStartRestoreoptionalInvoked when the user starts the restore process.
didFailLoadingProductsoptionalInvoked when errors occur during product loading. Return true to retry loading.
didPartiallyLoadProductsoptionalInvoked when products are partially loaded.
showAlertItemoptionalA binding that manages the display of alert items above the flow or paywall.
showAlertBuilderoptionalA function for rendering the alert view.
placeholderBuilderoptionalA function for rendering the placeholder view while the flow or paywall is loading. Defaults to a ProgressView.

Refer to the iOS - Handling events topic for more details on parameters.

Present as a non-modal view

You can also present flows and paywalls as navigation destinations or inline views within your app’s navigation flow. Use AdaptyFlowView directly in your SwiftUI views:

AdaptyFlowView(
    flowConfiguration: <AdaptyUI.FlowConfiguration>,
    didFailPurchase: { product, error in
        // Handle purchase failure
    },
    didFinishRestore: { profile in
        // Handle successful restore
    },
    didFailRestore: { error in
        // Handle restore failure
    },
    didReceiveError: { error in
        // Handle the error (rendering or JS exception from the flow script).
    }
)

Present flows and paywalls in UIKit

In order to display the flow or paywall on the device screen, do the following:

  1. Initialize the visual flow you want to display by using the AdaptyUI.flowController(with:delegate:) method:

    import AdaptyUI
    
    let visualFlow = try AdaptyUI.flowController(
        with: <AdaptyUI.FlowConfiguration>,
        delegate: <AdaptyFlowControllerDelegate>
    )

    Request parameters:

    ParameterPresenceDescription
    flowConfigurationrequiredAn AdaptyUI.FlowConfiguration object containing visual details of the flow or paywall. Use the AdaptyUI.getFlowConfiguration(forFlow:) method. Refer to Get flows and paywalls topic for more details.
    delegaterequiredAn AdaptyFlowControllerDelegate to listen to flow and paywall events. Refer to Handle flow & paywall events topic for more details.

    Returns:

    ObjectDescription
    AdaptyFlowControllerAn object representing the requested flow or paywall screen.
  2. After the object has been successfully created, you can display it on the screen of the device:

    present(visualFlow, animated: true)

If you’ve customized a paywall using the Paywall Builder, you don’t need to worry about rendering it in your mobile app code to display it to the user. Such a paywall contains both what should be shown within the paywall and how it should be shown.

To get the AdaptyUI.PaywallConfiguration object used below, see Fetch Paywall Builder paywalls and their configuration.

Present paywalls in SwiftUI

Present as a modal view

var body: some View {
  Text("Hello, AdaptyUI!")
      .paywall(
          isPresented: $paywallPresented,
          paywallConfiguration: <AdaptyUI.PaywallConfiguration>,
          didPerformAction: { action in
