Hi team,

The navigation bar in OCKDailyPageViewController is clear. And one can verify this visual bug when scrolling the content.
Please see the attachment below to find the details.

This issue happens in iOS 15.0+ devices, and it does not appear in iOS 14.0+ devices.

Can someone take a look? Thanks in advance!

Here's the fix

if #available(iOS 15.0, *) {
let navigationBarAppearance = UINavigationBarAppearance()
navigationBarAppearance.configureWithDefaultBackground()
UINavigationBar.appearance().standardAppearance = navigationBarAppearance
UINavigationBar.appearance().compactAppearance = navigationBarAppearance
UINavigationBar.appearance().scrollEdgeAppearance = navigationBarAppearance
}

Hi Magray,

Just tried your fix, it works! Thanks so much!
By the way, we don't need to set standardAppearance and compactAppearance. And the simplified version would be:

if #available(iOS 15.0, *) {
    let navigationBarAppearance = UINavigationBarAppearance()
    navigationBarAppearance.configureWithDefaultBackground()
    UINavigationBar.appearance().scrollEdgeAppearance = navigationBarAppearance
}
