How to change UITableViewCell based on height of iPhone model?

I am using a UITableViewController in my app. This works great, but I was wondering how I can do some small changes per device. The UITableViewCell height is not on all devices great. On iPhone 6/7 and Plus models it fits perfect, but on an iPhone SE/5 and 4 the rows are too big. I know that Interface Builder has a function called Vary of Traits, but when I select for example iPhone 4 and change the height of the UITableViewCell it will also be applied to all other sizes. So is this - different cell heights for different devices - possible and if yes, how can I add different cell heights based on different device heights?

you can calculate height of cell at runtime in 

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat{
}

for Example : let's assume that perfect cell height is 70 on Iphone 7 of view height 700,so you will code like 

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat{
        return self.view.frame.size.height * 0.1
}

so using this method your cell will always size 10% of your view's height

UITableView has a delegate method called heightForRowAt indexPath:

Within that method, you can write logic that defines the cell height as a proportion of screen height, tableView height, or whatever you need

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return // screenHeight (or tableViewHeight) / someNumberThatFitsYourNeeds
}
