handleInput() takes in an object of class `AnyObject` but should take in an object of class `Any` in order to support URLs

[naterock101]

In the AttachmentManager class

this method:

open func handleInput(of object: AnyObject) -> Bool {
        let attachment: Attachment
        if let image = object as? UIImage {
            attachment = .image(image)
        } else if let url = object as? URL {
            attachment = .url(url)
        } else if let data = object as? Data {
            attachment = .data(data)
        } else {
            return false
        }
        
        insertAttachment(attachment, at: attachments.count)
        return true
    }

the problem with this is if you try and input a URL from a video such as:

`@objc func imagePickerController(_: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey: Any]) {
    if let editedImage = info[.editedImage] as? UIImage {
        inputPlugins.forEach { _ = $0.handleInput(of: editedImage) }
    } else if let originImage = info[.originalImage] as? UIImage {
        inputPlugins.forEach { _ = $0.handleInput(of: originImage) }
    } else if let videoURL = info[.mediaURL] as? URL {
        inputPlugins.forEach  { _ = $0.handleInput(of: videoURL) }
    }
    getRootViewController()?.presentedViewController?.dismiss(animated: true, completion: nil)
    inputAccessoryView?.isHidden = false
}

`

you will get an error: "Argument type 'URL' expected to be an instance of a class or class-constrained type"

It seems that the issue lies in the definition of the method handleInput. The method is expecting an argument of type AnyObject, but URL is not a subclass of AnyObject, it's a struct. To resolve the issue, you need to change the definition of handleInput to accept a value of type Any instead:

so that method should look like this:

open func handleInput(of object: Any) -> Bool {
    let attachment: Attachment
    if let image = object as? UIImage {
        attachment = .image(image)
    } else if let url = object as? URL {
        attachment = .url(url)
    } else if let data = object as? Data {
        attachment = .data(data)
    } else {
        return false
    }
    
    insertAttachment(attachment, at: attachments.count)
    return true
}
