I have a class, MyURL, from a UIKit app that I wrote that handles all my URL needs, uploads, downloads, GETS, POSTS, etc.

I would like to use that class from within a SwiftUI view now. So within the MyURL I would pass binding vars that would cause my SwiftUI view to repudiate things such as statuses : percentage done, etc.

My issue is, how can I properly declare that class, myURL, from within the SwiftUI view, so that it doesn't get redeclared every time the view updates.

I wish I was better with terminology.

Thank you

struct ContentView: View {
	**var myURL = MyURL()**
	@State var proceed = false
    var body: some View {
        Button {
			myURL.pressed(proceed: $proceed)
        }
        label: {
            Text(proceed ? "pressed" : "not pressed")
        }
    }
    
}

class MyURL: NSObject, URLSessionDataDelegate,URLSessionTaskDelegate, URLSessionDelegate, URLSessionDownloadDelegate{

	func urlSession(_ session: URLSession, downloadTask: URLSessionDownloadTask, didFinishDownloadingTo location: URL) {
	}
	
	func pressed(proceed: Binding<Bool>) {
		print("\(proceed)")
		proceed.wrappedValue.toggle()
	}

	// Error received
	func urlSession(_ session: URLSession, task: URLSessionTask, didCompleteWithError error: Error?) {
		if let err = error {
			DispatchQueue.main.async { [self] in
				
				//code 
			}
		}
	}
	// Response received
	 func urlSession(_ session: URLSession, dataTask: URLSessionDataTask, didReceive response: URLResponse, completionHandler: (URLSession.ResponseDisposition) -> Void) {
			completionHandler(URLSession.ResponseDisposition.allow)

			if let httpResponse = response as? HTTPURLResponse {
				xFile?.httpResponse = httpResponse.statusCode
				DispatchQueue.main.async { [self] in

				if httpResponse.statusCode != 200 {
					
					//code

				}
			}
		}
	 }
	 
	// Data received
	 func urlSession(_ session: URLSession, dataTask: URLSessionDataTask, didReceive data: Data) {
			if xFile?.httpResponse == 200 {
			DispatchQueue.main.async { [self] in

					//code
				
			}
		 } //DispatchQueue.main.async
		 }
	 }

	func urlSession(_ session: URLSession, downloadTask: URLSessionDownloadTask, didWriteData bytesWritten: Int64, totalBytesWritten: Int64, totalBytesExpectedToWrite: Int64) {
	
		let num : Float = Float(totalBytesWritten * 100)
		let den : Float = Float(totalBytesExpectedToWrite * 100)
		let percentDownloaded : Int = Int(num/den * 100)
		DispatchQueue.main.async { [self] in

					//code
		}
	}

Hi @sergioq,

Apple has asked that questions about their proprietary frameworks, including UIKit and SwiftUI, be asked over at their own developer forums. Though it's possible that someone will be able to give you some helpful hints here, these forums are meant to be rather focused on using the Swift programming language itself.
