iOS 11 Beta 1 uses the increased navigation-bar title for almost all system-apps (it started doing this in iOS 10 and the Music app). I am wondering if Apple has a public API for this coming in iOS 11, or whether it will stay private for now.
The behavior is that the title has an increased font-size, is left aligned and will move to the navigation-bar once the user scrolls down. I've attached some screens showing this behavior in the Messages app here:
Although I could not find any reference in the UINavigationController and UINavigationBar so far, maybe someone knows some more details!

A user changes the navigation bar's style, or UIBarStyle , by tapping the “Style” button to the left of the main page. This button opens an action sheet where users can change the background's appearance to default, black-opaque, or black- translucent.
A navigation bar appears at the top of an app screen, enabling navigation through a hierarchy of content. A navigation bar also provides a natural place to display a screen's title — helping people orient themselves in your app or game — and it can include controls that affect the screen's content.
iPhone X added extra height for the Home Bar to toolbars and tab bars and their sizes are unchanged from iOS 11: 83 points tall in portrait and 53 points tall in landscape.
The only change done to UINavigationBar API for iOS 11 is prefersLargeTitles.

You can do it to your own apps with one small change: check "Prefers Large Titles" for your navigation bar in IB, or if you prefer to do it in code using:
navigationController?.navigationBar.prefersLargeTitles = true If you need to change the text attributes of the large title you need to use the new largeTitleTextAttributes property on UINavigationBar:
UINavigationBar.appearance().largeTitleTextAttributes = [ NSAttributedString.Key.foregroundColor: UIColor.black ] If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
