Crash on scan (NS7)

Hey guys,

When I hit scan on my app it crashes with the following log :

I disabled ‘beepOnScan’. It doesn’t crash on the simulator, only on a real device. Any idea ?

Hello all. Here the attribute “beepOnScan” worked on iOS 14 and V8 untime.

{N} 7 with V8 runtime:

├── nativescript@7.0.11
├── @nativescript/core@7.0.7
├── @nativescript/ios@7.0.3
├── nativescript-barcodescanner@4.0.1

Code:

export class QRCodeService
{
    private barcodeScanner: BarcodeScanner = new BarcodeScanner();

    /**
     * Open an pop-up to scan QR Codes.
     *
     * @param [options] Optional options that override defaults
     */
    public scan(options?: ScanOptions): Observable<ScanResult>
    {
        return from(this.barcodeScanner.scan({
            formats: 'QR_CODE',
            ...options,
            beepOnScan: false // Solves the crash
        }));
    }
}

@two-bridges thanks very much for your reply. I have reverted from v4.0.1 to v3.4.2 as our iOS platform is still on v6.5.4 due to memory issues in the latest iOS platform version. All looks good now. Many thanks.
