Hey there, it's my first time writing code in Xcode. when I´m trying to create a QRCode-generator i get the error message "Thread 1: EXCBADINSTRUCTION (code=EXCI386INVOP, subcode=0x0)" it would be great if someone could help me Thanks in advice! // //  QRCodeView.swift //  QR-Generator // //  Created by Darvin Mng on 19.01.21. // import Foundation import SwiftUI import CoreImage.CIFilterBuiltins struct QRCodeView : View {     let context = CIContext()     let filter = CIFilter.qrCodeGenerator()     var url : String          var body: some View {         Image(uiImage : generateQRCodeImage(url: url))             .interpolation(.none)             .resizable().frame(width: 150, height: 150, alignment: .center)     }          func generateQRCodeImage (  url : String) -> UIImage {         let data = Data(url.utf8)         filter.setValue(data, forKey: "inputMessage")                  if let qrCodeImage = filter.outputImage {             if context.createCGImage(qrCodeImage, from: qrCodeImage.extent) != nil {                 return UIImage(cgImage: qrCodeImage as! CGImage) Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)             }         }                      return UIImage(systemName: "xmark") ?? UIImage()     } }
