UILabel in UITableViewCell doesn't autoresize IOS 8. (autolayout)

Question

I have a table view with a basic autolayout for cells.My issue is that cell is autoresizing based on subviews, but it doesn't autoresize based on UILabel text, cell just stays at minimum height regardless of label text.I am really desperate as I have tried EVERY approach i could find on stack overflow and was struggling with this for 3 days.

//!--------Set youTableView------------------------//
youTableView.delegate = self
youTableView.dataSource = self
youTableView.allowsSelection = false
youTableView.bounces = true
youTableView.estimatedRowHeight = 100
youTableView.rowHeight = UITableViewAutomaticDimension
youTableView.registerClass(CommentNFTableViewCell.self, forCellReuseIdentifier: "Comment Cell")
youTableView.registerClass(LikeNFTableViewCell.self, forCellReuseIdentifier: "Like Cell")
youTableView.registerClass(ResponseNFTableViewCell.self, forCellReuseIdentifier: "Response Cell")
youTableView.registerClass(FollowNFTableViewCell.self, forCellReuseIdentifier: "Follow Cell")
youTableView.separatorInset = UIEdgeInsets(top: 0, left: 50, bottom: 0, right: 5) // move separator line
youTableView.tableFooterView = UIView()
self.youTableView.addSubview(youRefreshControl)
youRefreshControl.addTarget(self, action: "Get_You_Data", forControlEvents: UIControlEvents.ValueChanged)
