iOS 11 prefersLargeTitles not updating until scroll

Question

I implemented a basic UIViewController with a UITableView that\'s wrapped in a UINavigationController. I set prefersLargeTitles to true:

Similar issue for me with a UITableViewController added to a UIViewController. In my instance, these view controllers are themselves embedded in a UITabBarController and only the first tab displayed correctly used a large title. Other tabs required a manual scroll before the large title was displayed.

The only thing I could get to work was adjusting the contentInset as per @pau-senabre's answer, except I the top inset wasn't helpful for me. Instead, I set the left inset and then reset it on the next runloop.

private var isFirstAppearance = true

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    if isFirstAppearance {
        applyLargeTitlesFix()
    }
}

private func applyLargeTitlesFix() {
    let originalInset = tableViewController.tableView.contentInset
    tableViewController.tableView.contentInset = UIEdgeInsets(top: 0, left: 1, bottom: 0, right: 0)
    DispatchQueue.main.async { [weak self] in
        self?.tableViewController.tableView.contentInset = originalInset
    }
    isFirstAppearance = false
}
