I am trying to allow my users to make something like a collage in my app by pasting images into the canvasView, but I can't find any documentation on how to use the paste function for canvasView. I have tried the code below to paste from the UIPasteboard.general into the canvasView, and the system tells me the paste was successful but I don't see anything in the canvasView. Here is my function, called when the user taps the "paste" button in my UI:

Code Block private func pasteContent() {
        let pasteBoard = UIPasteboard.general
        
        if paste {
            if pasteBoard.hasImages {
                canvasView.paste(pasteBoard.image)
                paste.toggle()
            } else if pasteBoard.hasStrings {
                canvasView.paste(pasteBoard.string)
                paste.toggle()
            }
        }
    }

Also note, I am using SwiftUI, but this doesn't seem to work in regular swift either.

Any thoughts?

Same problem here, I think that there’s no posible to paste an image into canvasview.
