This is possible:

        let string1 = "blablabla"
        let charCountString1 = string1.character.characters.count

        tableView.rowHeight = CGFloat(charCountString1)
        return cell
    }

     else if indexPath.section == 1 {

        let cell = tableView.dequeueReusableCellWithIdentifier("TableViewCell2") as! HomePageTableViewCell2

        let imageHeight = imageView.frame.height

        tableView.rowHeight = CGFloat(imageHeight)
        return cell
    }
     else {

        let cell = tableView.dequeueReusableCellWithIdentifier("TableViewCell3") as! HomePageTableViewCell3

        let string3 = "ldsakjfalksdjflk"

Answer 2

you can always have the dynamic height for your tableView on the base of your content, no need to return the static height for just setup the constraints in your cell properly and always use preferred priority for content-hugging content-compressionResistance.

in -viewDidLoad just set

self.tableView.rowHeight = UITableViewAutomaticDimension
self.tableView.estimatedRowHeight = 60; // or whatever is suitable for you
