In macOS, I am encountering an issue where the system API fails to grant permission to open a file despite enabling the necessary Read/Write permissions within the SandBox. Could you please elucidate the reasons behind this behavior? Thanks!

func finderOpenFileSystem(at path: String) {
    let fileURL = URL(fileURLWithPath: path)
    
    guard FileManager.default.fileExists(atPath: path) else {
        print("Error: File does not exist at path: \(path)")
        return
    }
    
    let success = NSWorkspace.shared.open(fileURL)
    if success {
        print("File opened successfully: \(fileURL)")
    } else {
        print("Error: Failed to open file: \(fileURL)")
    }
}

To access files outside your app's sandbox, enable the "User Selected File" access type with read/write permissions in your app's entitlements. Then, use NSOpenPanel to allow the user to select the file or directory they want to access. This approach ensures that you can access the necessary files while maintaining the safety of your app from sandbox restrictions.
