Swift MessageKit problems - running swift 4.2

Question

I had just updated my code to swift 4.2 and fixed all the errors. Now I am trying to use 'MessageKit' to put a messenger into my app. Everything is updated yet I am having these problems... now it is saying for MessagesInputBarDelegate

"Use of undeclared type 'MessagesInputBarDelegate'"

and

"Use of undeclared type 'MessageInputBar'"

Also,

"Argument Labels '(type:)' do not match any available overloads"

and

"Cannot convert value of type'_?' to expected argument type 'URL?"

Use of undeclared type 'MessagesInputBarDelegate'

Use of undeclared type 'MessageInputBar'

extension CustomerChatViewController: MessagesInputBarDelegate {

func messageInputBar(_ inputBar: MessageInputBar, didPressSendButtonWith text: String) {
    let message = Message(user: user, content: text)

    save(message)
    inputBar.inputTextView.text = ""
}

}

Argument labels '(type:)' do not match any available overloads

let cameraItem = UIBarButtonItem(type: .system)

Cannot convert value of type '_?' to expected argument type 'URL?'

let imageName = [UUID().uuidString, String(Date().timeIntervalSince1970)].joined()
    storage.child(channelID).child(imageName).putData(data, metadata: metadata) { meta, error in
        completion(meta?.downloadURL())
    }

Answer 1

Have you install MessageInputBar ? You can install it like that

pod 'MessageInputBar'

Since MessageKit 2.0.0 you have to install MessageInputBar

If the MessageInputBar pod is required to use the MessageKit pod, it seems like the podspec of MessageKit should be updated to reflect that dependency. Manually adding a dependency to your own Podfile seems like a workaround rather than a real solution. – Sideway

@DávidPásztor you're right, I'll take a look at this more closely – Thousandth

Hi there, I'm doing the review rounds and I see you want to remove the MessageData part from the question. Why, is it unrelated to the other errors in the question? Next time just comment to the author and ask them to remove it! – Ballot

The error of message data cames because of a wrong import of another module. In addition there are another stack overflow post for that – Thousandth

For Carthage users, include this in your Cartfile: github "MessageKit/MessageInputBar" – Hardbitten

adding worked for me too then

import InputBarAccessoryView

then in viewDidLoad() add this :

override func viewDidLoad() {
        super.viewDidLoad()
        messageInputBar.delegate = self
        maintainPositionOnKeyboardFrameChanged = true
        messageInputBar.inputTextView.tintColor = .yellow
        messageInputBar.sendButton.setTitleColor(.purple, for: .normal)


        messagesCollectionView.messagesDataSource = self
        messagesCollectionView.messagesLayoutDelegate = self
        messagesCollectionView.messagesDisplayDelegate = self
        messagesCollectionView.messageCellDelegate = self

        messageInputBar.leftStackView.alignment = .center
        messageInputBar.setLeftStackViewWidthConstant(to: 50, animated: false)

    }

calling the delegate method :

extension ChatVC: MessageInputBarDelegate {

    func inputBar(_ inputBar: InputBarAccessoryView, didPressSendButtonWith text: String) {
        guard let user = self.user else{return}
        guard let uid = Auth.auth().currentUser?.uid else{return}
        let ref = Database.database().reference().child("messages").child(uid).child("personal").child(user.uid)
        let values = ["sender": uid, "text": text, "recipient": user.uid]
        ref.updateChildValues(values)
        inputBar.inputTextView.text = ""
    }
}
