Sendbird UIKit - iOS / Compilation error / SBUUserMessageCell

Greetings!

When I try to create a class in order to customize the chat messages, I’m getting an error at build time?
Other components work fine, no issues with most of them.
Any idea?
Using SendbirdUIKit, latest version.

My class

import Foundation
import SendbirdUIKit
import UIKit
    
class CustomUserMessageCell : SBUUserMessageCell
{
    override func setupStyles() {
        super.setupStyles()
        self.messageTextView.backgroundColor = .systemBlue
        self.messageContentView.backgroundColor = .black
        self.messageContentView.tintColor = .white
        
    }
}

Error message
