tableview cell how do we resize cell in swift along with image and label

Give constrain to your lable hight greater equal and put line to 0.

var pickheight: CGFloat = 0.0

Write this line in

override func viewDidLoad() {
        super.viewDidLoad()
        tableTrip.rowHeight = UITableViewAutomaticDimension
}

Method for increase tableview cell .

func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {

     pickheight = self.findHeightForText("Pass your text here like array value as String ", havingWidth: self.view.frame.size.width - 116, andFont: UIFont.systemFontOfSize(14.0)).height

     return "YOUR_DEFALUT_CELL_SIZE" + pickheight
}

Method for find text hight for cell..

func findHeightForText(text: String, havingWidth widthValue: CGFloat, andFont font: UIFont) -> CGSize {
        var size = CGSizeZero
        if text.isEmpty == false {
            let frame = text.boundingRectWithSize(CGSizeMake(widthValue, CGFloat.max), options: .UsesLineFragmentOrigin, attributes: [NSFontAttributeName: font], context: nil)
            size = CGSizeMake(frame.size.width, ceil(frame.size.height))
        }
        return size
}

1. set top,bottom,leading,trailing constraints for your label
2. set Attribute Inspector->lines to 0
3. set tableview.rowHeight = UITableViewAutomaticDimension in viewDidLoad() method
