OnMessageReceived, OnTagDiscovered event handlers are not working - Xamarin Forms - iOS

[NageshD-Obeliskstech]

Description

The events are subscribed to before StartListening(). But those are not getting called after the NFC tag read operation.

Expected Behavior

Usually, when the NFC tag reads successfully OnMessageReceived should get called and should publish the message.

Actual Behavior

Subscribed events (OnMessageReceived, OnMessagePublished, OnTagDiscovered) are not getting called.

@NageshD-Obeliskstech Are you sure CrossNFC.IsSupported, CrossNFC.Current.IsAvailable, CrossNFC.Current.IsEnabled values are all true for you? You likely haven't included entitlements in your build

[NageshD-Obeliskstech]

@saamerm Yes, the values of those all are true. And have added 'com.apple.developer.nfc.readersession.formats' for NDEF and TAG.

@NageshD-Obeliskstech are you testing the sample or just your own solution? Was it working before and it just stopped?

@NageshD-Obeliskstech did you ever get this working? I am having a similar issue.

[cbirsen]

I am having the same issue, would you please let me know if you ever solve it?

[saamerm]

@iaps and @cbirsen are you all trying the solution example in this repository and having this issue?

Unfortunately, having the same issue.. however it triggers the iOS cancelled event.

@jpsaccount are you trying this on the sample? And you’re not having any success?
