Addition to the existing answers:

If your custom title view is a view that already has an intrinsic content size by default (other than .zero), for example a UILabel, a UITextView or a UIButton, you can simply set

yourCustomTitleView.translatesAutoresizingMaskIntoConstraints = false

and it will automatically adjust to just enclose its contents, but never overlap with the left and right item views.

For example, you can drag a button into the title view area of a navigation bar in Interface Builder, create an outlet titleButton for it in your view controller and then do

override func viewDidLoad() {
    super.viewDidLoad()
    titleButton.translatesAutoresizingMaskIntoConstraints = false
}
