Showing CustomerCenterView() crashes the app since my rollout today

[ikemuc]

• I have updated Purchases SDK to the latest version
• I have read the Contribution Guidelines
• I have searched the Community
• I have read docs.revenuecat.com
• I have searched for existing Github issues

Since today's launch of my App in the Apple App Store, whenever you want to show CustomerCenterView(), my App crashes immediately.

When I go back to former versions, no crash happens, but instead of the regular CustomerCenterView I see a message "Update verfügbar. Bitte die App aktualisieren, damit alles korrekt funktioniert." (Translated: "Update available. Please update the app to ensure everything works correctly.") Below there are 2 buttons, one to Upgrade, which leads to my app's App Store page, and the other to continue. When I press continue in the old versions, the regular customer center appears.

But as I said: With my new version it crashes immediately.

1. Environment

   1. Platform: iOS 17 / iOS 18
   2. SDK version: 5.14.6 and 5.17.0
   3. StoreKit version:
      • StoreKit 1 (default on versions <5.0.0. Can be enabled in versions >=5.0.0 with .with(storeKitVersion: .storeKit1))
      • StoreKit 2 (default on versions >=5.0.0)
   4. OS version:
   5. Xcode version: 16.2
   6. Device and/or simulator:
      • Device
      • Simulator
   7. Environment:
      • Sandbox
      • TestFlight
      • Production
   8. How widespread is the issue. Percentage of devices affected.
      Apple released my App in the new version and all of my devices (3) and all of the simulators crash.

2. Debug logs that reproduce the issue. Complete logs with Purchases.logLevel = .verbose will help us debug this issue.

When I set a breakpoint to All Exceptions, it stops in the "structure MyApp: App" line with:
"Thread 1: "-[__SwiftValue set]: unrecognized selector sent to instance 0x600000c263d0""

3. Steps to reproduce, with a description of expected vs. actual behavior

Call a SwiftUI View, which includes CustomerCenterView(). It should open and display the data. But it crashes the whole app.

@ikemuc how are you showing CustomerCenterView? Would it be too much to ask for the code snippet?

I assume you're using it straight away, but I wonder if you're wrapping it inside a NavigationStack, NavigationView, or presenting it.

[ikemuc]

This is the code currently:

`
import Foundation
import SwiftUI
import RevenueCatUI

struct CustomerCenterSheetView: View {
@Environment(MainModel.self) var mainModel
@Environment(.presentationMode) var presentationMode

@State private var currentSheetHeight: CGFloat = 0

var body: some View {
    @Bindable var mainModel = mainModel
    
    Text("")
        .sheet(isPresented: $mainModel.customerCenterVisible, onDismiss: {
        onClose()
    }) {
        CustomerCenterView()
            .foregroundColor(Color("uiForegroundDark"))
            .presentationDetents([
                .height(UISettings.customerCenteriOSSheetHeight),
            ])
            .presentationDragIndicator(.visible)
            .onDisappear {  // necessary for iOS17
                onClose()
            }
    }

}

private func onClose() {
    mainModel.sheetWasClosed(mode: .customerCenter)
}

}
`

[ikemuc]

Even simpler - This is enough:

import SwiftUI
import SwiftData
import XCGLogger
import RevenueCatUI

@main
struct SunOnlyApp: App {
    var body: some Scene {
        WindowGroup {
            CustomerCenterView()
        }
   }
}

Some more research:

The crash also happens, when I build my App with purchases-ios 5.14.0 (the first version with CustomerCenterView).

I tried somethings else:
When I switch the simulator or the device to airplane mode before opening the view containing CustomerCenterView(), I get an error message ("Es ist etwas schief gelaufen", i.e. "Something went wrong") instead of the crash.

=> Could this be a RevenueCat server problem? It looks like this, because my earlier app versions, which were working without any problems now show this strange "Update" warning...

[facumenzella]

I think this is the root cause @ikemuc #4792
Can you try that commit?

[ikemuc]

I tried it:
CustomerCenterView() still crashes...

BTW: I reduced the pressure on me by replacing CustomerCenterView() with my old code in a nightly emergency rollout of a new version of SunOnly. So for me the fix isn't time critical any more...

@ikemuc would it be too much to ask for the logs =)?

Complete logs with Purchases.logLevel = .verbose will help us debug this issue.

[facumenzella]

@ikemuc for the heads up, you can disable the update warning from the dashboard.

[ikemuc]

Ah, I thought that CustomerCenterView() displays this message because of a necessary update of RevenueCat software... Now I understand the message...

Would disabling the warning message in the dashboard prevent the crash?

[facumenzella]

I don't think it's related tbh. Just so you know you can disable it :)

Whenever you have the logs, please also attach the user ID. That will narrow down the issue 🙏 @ikemuc

[ikemuc]

Here comes the log with verbose loglevel.

revenuecat.log

[ikemuc]

Yep, I tried switching of the update warning. It still crashes...

[facumenzella]

@ikemuc I've been trying to reproduce the crash without luck. Do you think we can schedule a call to debug and see what's going on? Just book some slot. Hopefully we'll figure it out pretty quickly
