How to dynamically adjust table view height depending on its content? I got this perfect solution from this stackoverflow post. Below is the detail of the post.

Solution

Lots of the answers here don’t honor changes of the table or are way too complicated. Using a subclass of UITableView that will properly set intrinsicContentSize is a far easier solution when using autolayout. No height constraints etc. needed.

class UIDynamicTableView: UITableView
{
    override var intrinsicContentSize: CGSize {
        self.layoutIfNeeded()
        return CGSize(width: UIViewNoIntrinsicMetric, height: self.contentSize.height)
    }

    override func reloadData() {
        super.reloadData()
        self.invalidateIntrinsicContentSize()
    }
}

Set the class of your TableView to UIDynamicTableView in the interface builder and watch the magic as this TableView will change it’s size after a call to reloadData().

Intrinsic Content Size

So what is Intrinsic Content Size?
