MLKitBarcodeScanner crashing on iOS on NS7

[dammynex]

I have "@nativescript/firebase": "^11.0.0"

Then: import { MLKitBarcodeScanner } from '@nativescript/firebase/mlkit/barcodescanning'

And on the scan page: <MLKitBarcodeScanner width="320" height="320" @scanResult="onBarcodeScanningResult"> </MLKitBarcodeScanner>

And it just crashes after page is opened

Update:

I switched "@nativescript/ios": 7.x.x to "@nativescript/ios": "JSC"

And it works fine. So I think the issue is with the new iOS V8 engine.

I get a crash on iOS running V8 as well while it works with JSC / using

"@nativescript/ios": "6.5.3",

instead.

@EddyVerbruggen could you have a look, please?

[SmailHammour]

@EddyVerbruggen could you please have a look at this? This is really blocking for some of us.

@SmailHammour @EddyVerbruggen I am in the same situation, has someone found a solution?

@SmailHammour @EddyVerbruggen I am in the same situation, has someone found a solution?

The only thing you can do is use JSC instead of v7. We will have to wait until @EddyVerbruggen finds the time to fix this.

[vallemar]

Thank you very much @SmailHammour, with this version it works perfect but the performance of components such as RadListView is much lower... I am waiting to correct this

[SmailHammour]

@EddyVerbruggen whats the status on this?
