How do I export and import data via Files app on macOS using Swift?

In this guide, we'll explore how to export and import data via the Files app on macOS using Swift. This functionality can be useful for applications that need to save data persistently or load files from the user's system.

Using the FileManager class in Swift, developers can easily access files and directories. Below is an example of implementing file import and export using Swift.


    import Cocoa
    import Foundation

    // Function to export data
    func exportData(data: String) {
        let fileManager = FileManager.default
        let savePanel = NSSavePanel()
        savePanel.allowedFileTypes = ["txt"]
        
        savePanel.begin { (result) in
            if result == .OK, let url = savePanel.url {
                do {
                    try data.write(to: url, atomically: true, encoding: .utf8)
                    print("Data exported successfully!")
                } catch {
                    print("Error exporting data: \(error)")
                }
            }
        }
    }

    // Function to import data
    func importData() {
        let openPanel = NSOpenPanel()
        openPanel.allowedFileTypes = ["txt"]
        
        openPanel.begin { (result) in
            if result == .OK, let url = openPanel.url {
                do {
                    let importedData = try String(contentsOf: url, encoding: .utf8)
                    print("Data imported successfully: \(importedData)")
                } catch {
                    print("Error importing data: \(error)")
                }
            }
        }
    }
