@shahthepro It seems like you have to use Mac Catalyst since UIDocumentPickerViewController doesn't support macOS natively. https://developer.apple.com/documentation/uikit/uidocumentpickerviewcontroller?language=objc

AppKit has a different API instead of UIDocumentPickerViewController for dealing with save and open dialogs. https://github.com/hsjoberg/blixt-wallet/blob/431ff0d60a423c44d77ba48be46da026b92b6bd0/ios/LndMobile/LndMobileTools.swift#L227-L252

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.
