UISearchBar translucency at iOS SKD 9.3

Question

After updating Xcode to 7.3 (iOS SDK 9.3) my UISearchBar ignores setting transluent property. This code worked well before update.

override func viewDidLoad() {
    super.viewDidLoad()

    print("viewDidLoad: \(searchBar.translucent)")
    searchBar.translucent = false
}

override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
    searchBar.translucent = false
    print("viewWillAppear: \(searchBar.translucent)")
}

override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)
    searchBar.translucent = false
    print("viewDidAppear: \(searchBar.translucent)")
}

Now this code prints

viewDidLoad: true

viewWillAppear: true

viewDidAppear: true

My UISearchBar has default search style
