iOS App Crashes After Push Notification Permission

[ibrahimdevs]

Hi,

Because of plugin's swizzling mechanism I'm getting crash error. I'm asking push notification permission request. When user click "Allow" for push permission, my app is crashing randomly, not every time. I'm getting this error on iOS devices.

My flutter version 3.0.5 and dart 2.17.6. I'm using adapty_flutter 1.0.12 and onesignal_flutter 3.3.2. This error comes from one of them but I'm not sure which one.

Hi, @ibrahimdevs! I would suggest you to opt out of Adapty swizzling mechanism just to check everything else is fine. For now I'm not sure this is our issue, but we will investigate it and I will come back to you soon.

[ibrahimdevs]

Hi, @x401om thanks for quick workaround but I think that it is not an option for Flutter SDK. Because current flutter SDK is based on iOS 1.16.10 which is not supporting to opt out Adapty swizzling. This feature has been added on newer versions.

[x401om]

@ibrahimdevs actually it is the option for underlying iOS SDK and it presented from the beginning. Flutter SDK does not require any additional settings, you just need to add the AdaptyAppDelegateProxyEnabled key with the value NO to the app's Info.plist

[ibrahimdevs]

@x401om thanks for clarification. I messed it with in AppDelegateSwizzler.swift:

#if ADAPTY_DISABLE_PUSHES
#else

So I disabled it with "AdaptyAppDelegateProxyEnabled" now.

I opened this issue on OneSignal's Repo too, maybe this issue could help you to solve it. https://github.com/OneSignal/OneSignal-Flutter-SDK/issues/577

[x401om]

@ibrahimdevs are you able to reproduce this crash after disabling this feature?

[ibrahimdevs]

@x401om it was a random bug, so I'm not 100% sure but I think disabling this feature fixed this issue. I published an update 2 days ago, after that there is no error.

[kellvembarbosa]

I'm having the same problem and the percentage of crashes is pretty high.

[kellvembarbosa]

@ibrahimdevs updates about this bug?

[x401om]

Hi everyone! We are planning to remove this feature in the next releases (I mean promos and therefore APNS support and swizzling mechanism), so feel free to disable this using the workaround described above. At the moment I will not close this issue until it will be done.

[ibrahimdevs]

@kellvembarbosa I disabled this mechanism with this workaround below. And it is working fine now.
