I have begun to try to use MessageKit from the Firebase Chat tutorial that uses MessageKit so far. I have come across this error that does not appear inside the tutorial project. When I try to use the code from the tutorial project I am getting this error and am not sure how to solve it.

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

let cameraItem = UIBarButtonItem(type: .system)

You are saying:

let cameraItem = UIBarButtonItem(type: .system)

So the problem appears to be that you do not know how to copy and paste, because that is not what the original tutorial says! It says:

let cameraItem = InputBarButtonItem(type: .system)

And that is a completely different thing. InputBarButtonItem is part of MessageKit and won't give you this error if you've installed MessageKit correctly and if you write the code as the tutorial says.

You cannot create an UIBarButtonItem like that because it's not part of the documentation. Here is the official documentation of UIBarButtonItem with different initialisers.

If you want to create a UIBarButtonItem with default system items:

UIBarButtonItem(barButtonSystemItem: .cancel, target: self, action: Selector("handleCancel")

Here is a list of all UIBarButtonItem.SystemItem that you can use to create a UIBarButtonItem

You can also create a UIBarButtonItem with different data, like images, text etc... Take a look at this page
