Im getting a scoping error in the default App.swift file of my Xcode project and ive done everything to try to solve the issue, my ContentView struct is at the top level, ive cleaned the build folder a hundred times, restarted Xcode, cleared the derived data folder for nothing to happen. Here is my ContentView.swift file below.

    protocol runPyAndSendRequestRunnable {
        func runPyServer() -> String
        func sendRequest(inputText: String, completion: @escaping(String) -> Void)
    }
    
    
    func runPyServer() -> String {
        print("server run")
        return "server run"
    }
    
    func sendRequest() -> String {
        print("request sent")
        return "request sent"
    }
    
    
    
    struct MyPyType: runPyAndSendRequestRunnable {
        func runPyServer() -> String {
            return "server started"
        }
        
        func sendRequest(inputText: String,completion: @escaping(String) ->Void) {
            let userInput = inputText
            guard let url = URL(string:"http://localhost:8080/MacGPT") else {
                completion("Error: failed to obtain url")
                return
                
            }
        }
        
       
            struct ContentView: View {

The error is occurring because you have nested your ContentView struct within the MyPyType struct, which is causing the ContentView to be scoped inside MyPyType and not at the top level. To fix the scoping error, you need to move the ContentView struct to the top level, outside of MyPyType. Here's the modified code:

protocol runPyAndSendRequestRunnable {
    func runPyServer() -> String
    func sendRequest(inputText: String, completion: @escaping (String) -> Void)
}

func runPyServer() -> String {
    print("server run")
    return "server run"
}

func sendRequest() -> String {
    print("request sent")
    return "request sent"
}

struct MyPyType: runPyAndSendRequestRunnable {
    func runPyServer() -> String {
        return "server started"
    }

    func sendRequest(inputText: String, completion: @escaping (String) -> Void) {
        let userInput = inputText
        guard let url = URL(string: "http://localhost:8080/MacGPT") else {
            completion("Error: failed to obtain url")
            return

        }
    }
}

struct ContentView: View {
    var viewController: runPyAndSendRequestRunnable? = MyPyType()

    @State private var text: String = ""
    @State private var filePath = ""
    @State private var inputText = ""

    var body: some View {
        makeContent()
            .onAppear {
                NSApp.mainWindow?.makeFirstResponder(NSApp.mainWindow?.contentView)
            }
    }

    // ... rest of the code ...

    struct ContentView_Previews: PreviewProvider {
        static var previews: some View {
            ContentView()
        }
    }
}

Now, the ContentView struct is at the top level, and the scoping error should be resolved. Make sure that your ContentView.swift file only contains the ContentView struct, and you should be good to go.

this is already how my code is structured. I got this same response from chat gpt it still doesn't solve the contentview() scope error that I get in the App.swift file

The error doesn’t get generated in this file aka the ContentView.swift file but instead xcode brings up the default App.swift file(in my case its Mac_GPTApp.swift) and shows a “Cannot find ContentView() in scope” error for the line ContentView().
