If you're working with a storyboard or xib, you can change the UITextView's Return button to 'Done' (or various other options) within Interface Builder, without the need for any setup code. Just look for this option in the Attributes inspector:

From there, you just pair it up with the UITextViewDelegate code that others have already provided here.

Swift v5:

extension ExampleViewController: UITextViewDelegate {

    func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool {
        if (text == "\n") {
            textView.resignFirstResponder()
        }
        return true
    }
}

And then, in your viewDidLoad() method:

exampleTextView.delegate = self
