Issue with markdown render/convert to attribute string on macOS latest version

[sirily11]

Cannot use the either down.toAttributedString() and DownView on MacOS. The error was shown when using down.toAttributedString()

And following error was thrown when using DownView

The markdown string I use is simply a "Hello world" string. I also tried using the example from readme, but failed. The project also using swiftUI with NSViewRepresentable to wrap the DownView.

This also happens when using it in ios project

Ok. I got the solution. If you are using SwiftUI and bind this view using UIViewRepresentable or NSViewRepresentable, then toNSAttributedString should be running inside DispatchQueue.main.async. Otherwise, it will throw an error. I don't know the reason.

Because UIKit doesn't work on background threads. This isn't just for SwiftUI, but iOS in general.
