File Picker File just randomly stops working

Hello everyone, a a few days ago I coded a file picker struct in UIKit and it was working fine, the app I implemented it in even ran on my device no problems. Now all of a sudden, it gives me errors (Type 'FilePicker' does not conform to protocol 'UIViewControllerRepresentable') and refuses to compile. I changed absolutely nothing in the file... Does anybody know why this is giving errors all of a sudden?

import SwiftUI
import UIKit

struct FilePicker: UIViewControllerRepresentable {
    @Binding var isShown: Bool
    @Binding var fileURL: URL?

    func makeUIViewController(context: UIViewControllerRepresentableContext<FilePicker>) -> UIDocumentPickerViewController {
        let picker = UIDocumentPickerViewController(documentTypes: ["public.data"], in: .import)
        picker.delegate = context.coordinator
        return picker
    }

    func updateUIViewController(_ uiViewController: UIDocumentPickerViewController, context: UIViewControllerRepresentableContext<FilePicker>) {

    }

    func makeCoordinator() -> Coordinator {
        Coordinator(self)
    }

    class Coordinator: NSObject, UIDocumentPickerDelegate {
        var parent: FilePicker

        init(_ parent: FilePicker) {
            self.parent = parent
        }

        func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {
            parent.fileURL = urls[0]
            parent.isShown = false
        }

        func documentPickerWasCancelled(_ controller: UIDocumentPickerViewController) {
            parent.isShown = false
        }
    }
}
