@shahthepro It seems like you have to use Mac Catalyst since UIDocumentPickerViewController doesn't support macOS natively.

AppKit has a different API instead of UIDocumentPickerViewController for dealing with save and open dialogs.

Here's a simple example in Swift on how to open a file

DispatchQueue.main.async {
  do {
    let panel = NSOpenPanel()
    panel.allowsMultipleSelection = false
    panel.canChooseDirectories = false
    if panel.runModal() == .OK {
      if let u = panel.url {
       let base64 = try Data(contentsOf: u).base64EncodedString())
      } else {
        // error
      }
    } else {
      // ...
    }
  }
  catch {
   // exception
 }
}

It seems to be hard because AppKit has NSOpenPanel and NSSavePanel separately.
maybe we have to make separate package to support macOS.

#612 added the barebones support
can anyone test this one in ios, because i currently don't have a stable ios build of my app

I have tested only on mac os
