How to use with CocoaPods

Inizia con il Podfile, DotnetNewBindings.swift e le impostazioni .csproj descritte nella riproduzione, quindi esamina l’output dell’archivio xcodebuild relativo al framework Pods_NewBinding mancante e cerca nel repository il punto di ingresso della build dei bindings nativi. Il lavoro è completato quando la configurazione CocoaPods documentata può completare dotnet build/archive per arm64 senza l’errore del linker segnalato.

Hello!

I've tried to bind MLKit BarcodeScanning for iOS.

1. Initialize cocoapods : pod init
2. Add pod to Podfile: pod 'GoogleMLKit/BarcodeScanning', '7.0.0'
3. Run pod install
4. Add new method to DotnetNewBindings.swift:

   @objc
       public static func detectBarcodes(image: UIImage) async throws -> String? {
           
           let format = BarcodeFormat.all
           let barcodeOptions = BarcodeScannerOptions(formats: format)
           
           let barcodeScanner = BarcodeScanner.barcodeScanner(options: barcodeOptions)
           
           let visionImage = VisionImage(image: image)
           visionImage.orientation = image.imageOrientation
           
           let barcodes = try await barcodeScanner.process(visionImage)
           guard !barcodes.isEmpty else {
               return nil
           }
           
           for barcode in barcodes {
               return barcode.displayValue
           }
           
           return nil
       }
   

5. Ensure the target platform is arm64 (It doesn't work with emulators)
6. Build project. Build passed.
7. Add <RuntimeIdentifiers>ios-arm64;</RuntimeIdentifiers> in csproj
8. Run dotnet build.

I get errors:
