Autoadapt height of View - ios

Question

I m building a chat View in xCode with swift language.
I m create two custom cell one to sender message and another one to received message. The problem is when the text of message is greater than the width of the screen of iPhone. Then I need to configure the two views to increase the height if the text is too big.
So this is my view:
I configured the height of View Lbl Message >= 30 but if you see xCode set to RED that constraint and for me the error is in that part.
Anyway this is the result of my iPhone when application stil running:
If you check with more attention after the text "mio" in the blue cell you can see that there are other text but it is not displayed.
EDIT
I added ChatVC controller where is the UITableView:

This is chatCell class
import UIKit
class ChatCell: UITableViewCell {

#IBOutlet weak var viewLblMessage: UIView!
#IBOutlet weak var lblTime: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
self.viewLblMessage.setCornerRadius(cornerRadius: 10, borderColor: nil, borderWidth: nil)
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
}

If you don't know the size of the text, don't add height to the view. You should add your constraints without adding height
