I want to check network reachability using Alamofire. This is the code: var body: some Scene {         WindowGroup {             NetworkReachabilityManager()!.startListening { status in                 switch status {                     case .notReachable, .unknown:                         Text("No internet")                             .bold()                             .padding(.horizontal, 2)                             .frame(maxWidth: .infinity)                             .background(Color(hex: 0xce01e37))                             .foregroundColor(Color.white)                 default : ()                 }             } ... But this error keeps showing: Static method 'buildBlock' requires that 'Bool' conform to 'View' Any solutions ?

I'm trying to add functionality to save a picture from a URL to the user's photo library. here's the code: import Foundation import UIKit class ImageDownloader: NSObject { static func writeToPhotoAlbum(imageUrl: String) { let imageURL = URL(string: imageUrl)! if let image = try? Data(contentsOf: imageURL) { UIImageWriteToSavedPhotosAlbum(UIImage(data: image)!, self, nil, nil) } } @objc func saveCompleted( _ image: UIImage, didFinishSavingWithError error: Error?, contextInfo: UnsafeRawPointer) { print("Save finished!") } } When i call the method like this: ImageDownloader.writeToPhotoAlbum(imageUrl: "image_url") I get this error: ImageDownloader does not respond to selector Any explanation and solution?
