phonegap-nfc plugin causes error on startup on IOS

[alexdev888]

Platform: Ionic + Capacitor + Angular
Target device: iPhone SE

When I run my app on iPhone after I install phonegap-nfc plugin the app crashes.
The idea is that iPhone SE has NFC only for payments.
I need at list app to start without error, but after installing NFC plugin I get this on compiling App in Xcode:

dyld`__abort_with_payload:
0x100902390 <+0>: mov x16, #0x209
0x100902394 <+4>: svc #0x80
-> 0x100902398 <+8>: b.lo 0x1009023b0 ; <+32>
0x10090239c <+12>: stp x29, x30, [sp, #-0x10]!
0x1009023a0 <+16>: mov x29, sp
0x1009023a4 <+20>: bl 0x1009017d0 ; cerror_nocancel
0x1009023a8 <+24>: mov sp, x29
0x1009023ac <+28>: ldp x29, x30, [sp], #0x10
0x1009023b0 <+32>: ret

How can I make this plugin to not be loaded if phone does not support NFC on IOS?
Any solution?

I too have this issue any advice, please?

[JoshuvaGeorge03]

@alexdev888 How do you fixed this issue?

[don]

The fix should be to make a weak reference to CoreNFC in plugin.xml. I haven't duplicated this yet, but pull request #395 should be the fix.

[JoshuvaGeorge03]

@don how to use that pull request?

[don]

To try a different branch, remove the existing plugin

cordova plugin rm phonegap-nfc

Then install the version from the PR using the git URL

cordova plugin add https://github.com/M3skar/phonegap-nfc

I managed to track down an iPhone SE so hopefully I'll be able to test this soon.

[don]

I can not duplicate this.

• iPhone SE with iOS 13.2
• Cordova 9.0.0
• cordova-ios 5.1.1
• Xcode 11.4 (11E146)

If someone can duplicate this, please post details here.

I verified my provisioning profile and NFC Tag Reading is enabled.

Any help is highly appreciated !

[JoshuvaGeorge03]

@don is this pull request support WKWebView?

Is this have every feature as current nfc plugin?

[don]

@just4give you're seeing a different error maybe related to #363

[just4give]

@don thanks for sharing that. I installed that PR and now enabled() is working but beginSession does not seem to work. Not getting enough information in the log. Not sure if you can put some light on this?

Code

ionViewDidEnter() {

      console.log("lets start NFC session ")
      this.nfc.beginSession(

        error => alert('Failed to start session ')
      );

    
    },
    (error)=>{alert('NFC Not enabled'+error)});

  }

As error message does not indicate anything clearly , I am kind of lost where to go from here :(

[don]

Fixed in #399

beginSession is deprecated. Use scanNdef instead since it returns a Promise. The Ionic wrapper isn't updated yet, so use (<any>window).nfc.scanNdef() until it's updated.
