CollectionVIewCell Text Rendering Issues

So I have a comments feature in my app that users use to communicate. Each comment has a pic, some text,a button that lets you either flag or reply to comments, and the how long ago the comment was posted. As seen in the picture below

enter image description here

However as seen in the picture there is a clear problem. Depending on the amount of text typically anything that spans one line or more. The time label does not show.

import Foundation
import UIKit
import Firebase

protocol CommentCellDelegate: class {
    func optionsButtonTapped(cell: CommentCell)
    func handleProfileTransition(tapGesture: UITapGestureRecognizer)
}
class CommentCell: UICollectionViewCell {
    weak var delegate: CommentCellDelegate? = nil
    override var reuseIdentifier : String {
        get {
            return "cellID"
        }
        set {
            // nothing, because only red is allowed
        }
    }
    var didTapOptionsButtonForCell: ((CommentCell) -> Void)?

    weak var comment: CommentGrabbed?{
        didSet{
            guard let comment = comment else{
                return
            }
          //  print("apples")
            // textLabel.text = comment.content
            //shawn was also here
            profileImageView.loadImage(urlString: comment.user.profilePic!)
            //  print(comment.user.username)
            let attributedText = NSMutableAttributedString(string: comment.user.username!, attributes: [NSAttributedStringKey.font: UIFont.boldSystemFont(ofSize: 14)])

            attributedText.append(NSAttributedString(string: " " + (comment.content), attributes: [NSAttributedStringKey.font: UIFont.systemFont(ofSize: 14)]))

            attributedText.append(NSAttributedString(string: "\n\n", attributes: [NSAttributedStringKey.font: UIFont.systemFont(ofSize: 4)]))
            let timeAgoDisplay = comment.creationDate.timeAgoDisplay()
            attributedText.append(NSAttributedString(string: timeAgoDisplay, attributes: [NSAttributedStringKey.font: UIFont.systemFont(ofSize: 12), NSAttributedStringKey.foregroundColor: UIColor.gray]))

            textView.attributedText = attributedText


        }
    }

    lazy var textView: UITextView = {
        let textView = UITextView()
        textView.font = UIFont.systemFont(ofSize: 14)
        textView.isScrollEnabled = false
        textView.textContainer.maximumNumberOfLines = 2
        textView.textContainer.lineBreakMode = .byCharWrapping
        textView.isEditable = false
        return textView
    }()

    lazy var profileImageView: CustomImageView = {
        let iv = CustomImageView()
        iv.clipsToBounds = true
        iv.isUserInteractionEnabled = true
        iv.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleProfileTransition)))
        iv.contentMode = .scaleAspectFill
        return iv
    }()

    lazy var flagButton: UIButton = {
        let flagButton = UIButton(type: .system)
        flagButton.setImage(#imageLiteral(resourceName: "icons8-Info-64"), for: .normal)
        flagButton.addTarget(self, action: #selector(optionsButtonTapped), for: .touchUpInside)
        return flagButton
    }()

    @objc func optionsButtonTapped (){
        didTapOptionsButtonForCell?(self)
    }

    @objc func onOptionsTapped() {
        delegate?.optionsButtonTapped(cell: self)
    }
    @objc func handleProfileTransition(tapGesture: UITapGestureRecognizer){
        delegate?.handleProfileTransition(tapGesture: tapGesture)
      //  print("Tapped image")
    }



    override init(frame: CGRect){
        super.init(frame: frame)
        addSubview(textView)
        addSubview(profileImageView)
        addSubview(flagButton)
        textView.anchor(top: topAnchor, left: profileImageView.rightAnchor, bottom: bottomAnchor, right: flagButton.leftAnchor, paddingTop: 4, paddingLeft: 4, paddingBottom: 4, paddingRight: 4, width: 0, height: 0)
        profileImageView.anchor(top: topAnchor, left: leftAnchor, bottom: nil, right: nil, paddingTop: 8, paddingLeft: 8, paddingBottom: 0, paddingRight: 0, width: 40, height: 40)
        profileImageView.layer.cornerRadius = 40/2
        flagButton.anchor(top: topAnchor, left: nil, bottom: nil, right: rightAnchor, paddingTop: 4, paddingLeft: 0, paddingBottom: 0, paddingRight: 4, width: 40, height: 40)
        flagButton.addTarget(self, action: #selector(CommentCell.onOptionsTapped), for: .touchUpInside)

    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}

I figured it was my constraints but it doesn't seem like it is. Does anyone have any idea why this would happen?

Autosizing works only when maximumNumberOfLines is zero.

textView.textContainer.maximumNumberOfLines = 0
