iOS26 Beta3 - cannot purchase subscription using originalTemplatePaywallFooter

Hey ​@mrd,

Thank you for reporting this. We will check it out!

In the meantime, would you mind sharing a complete code snippet of your implementation so we can reproduce it?

Hi ​@alejandra-wetsch 

 thanks for the reply. I haven’t run this code because to test with offerings and PaywallV1 I would have to setup a whole new revenue cat project with offerings and paywalls, but the gist of the code is something like this, there is a UIKit UIView, that hosts a SwiftUI View that creates the RC paywall footer, when I click on the “Continue” button in the RC footer to make a purchase I get the error: 

[Presentation] Attempt to present <UIAlertController: 0x113e85200> on <UIViewController: 0x114ae8800> (from <UIViewController: 0x114ae8800>) whose view is not in the window hierarchy.

And the iOs purchase dialog never appears, so you can’t purchase anything.

I haven’t been able to run this code properly because of having to setup a whole new revenue cat project to test it, but the gist of the code looks like below:

import UIKit
import SwiftUI
import RevenueCat
import RevenueCatUI

class ViewController: UIViewController {

  override func viewDidLoad() {
    super.viewDidLoad()
    Task {
      await setupRC()
    }
  }

  private func setupRC() async {
    Purchases.logLevel = .debug

    var configBuilder = Configuration.Builder(withAPIKey: "YOUR_REVENUCAT_API_KEY_HERE")

    configBuilder = configBuilder
      .with(appUserID: UUID().uuidString)
      .with(networkTimeout: 10.0)

    Purchases.configure(with: configBuilder.build())

    do {
      guard let offering = try await Purchases.shared.offerings().current else {
        print("no offerings found")
        return
      }

      showPaywall(offering: offering)
    } catch {
      print("failed to fetch offerings")
    }
  }

  func showPaywall(offering: Offering) {
    let vc = UIViewController()
    vc.view = PaywallView(offering: offering)
    vc.isModalInPresentation = true
    vc.modalPresentationStyle = .formSheet
    self.present(vc, animated: true)
  }
}

final class PaywallView: UIView {
  private let offering: Offering

  init(offering: Offering) {
    self.offering = offering
    super.init(frame: CGRect.zero)
    createContentView()
  }

  required init?(coder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
  }

  private func createContentView() {
    // The content of our paywallview is a swiftui view

    let contentView = PaywallContentView(offering: offering)
    let hostingView = UIHostingController(rootView: contentView)
    hostingView.view.backgroundColor = .none
    addSubview(hostingView.view!)
    NSLayoutConstraint.applyConstraints([
      hostingView.view!.leadingAnchor.constraint(equalTo: leadingAnchor),
      hostingView.view!.trailingAnchor.constraint(equalTo: trailingAnchor),
      hostingView.view!.bottomAnchor.constraint(equalTo: bottomAnchor),
      hostingView.view!.topAnchor.constraint(equalTo: topAnchor)
    ])
  }
}

struct PaywallContentView: View {
  let offering: Offering

  var body: some View {
    ScrollView {

    }
    .scrollDisabled(true)
    .originalTemplatePaywallFooter(
      offering: offering,
      condensed: true,
      fonts: CustomPaywallFontProvider(fontName: "FoundersGrotesk-Regular"),
      purchaseStarted: { package in
        print("purchase started")
      },
      purchaseCompleted: { customerInfo in
        print("purchase completed")
      },
      purchaseCancelled: {
        print("purchase cancelled")
      },
      restoreStarted: nil,
      restoreCompleted: nil,
      purchaseFailure: { error in
        print("purchase failed")
      },
      restoreFailure: nil
    )
  }
}

extension NSLayoutConstraint {
  public class func applyConstraints(_ constraints: [NSLayoutConstraint], priority: UILayoutPriority? = nil) {
    for constraint in constraints {
      if let view = constraint.firstItem as? UIView {
        view.translatesAutoresizingMaskIntoConstraints = false
      }

      if let priority = priority {
        constraint.priority = priority
      }
    }
    NSLayoutConstraint.activate(constraints)
  }
}

Hey ​@mrd, 

Thank you for the additional details. I will try to reproduce this myself locally and get back to you as soon as I have more information! 

Please let me know if you have any other questions or if there’s anything else I can do for you!

Thank you for confirming, Mark! 

We will keep this scenario under our radar.
