The background color of the navigation bar of "Photo Library" displayed by WKWebView in iOS15 does not work with the backgroudColor of UINavigationBarAppearance().

It works on iOS14.

AppDelegate.swift

if #available(iOS 15, *) {
    let appearance = UINavigationBarAppearance()
    appearance.backgroundColor = .red
    UINavigationBar.appearance().standardAppearance = appearance
    UINavigationBar.appearance().scrollEdgeAppearance = appearance
    UINavigationBar.appearance().compactAppearance = appearance
} else {
    UINavigationBar.appearance().barTintColor = .red
}

ViewController.swift

let webConfiguration = WKWebViewConfiguration()
webView = WKWebView(frame: .zero, configuration: webConfiguration)
webView.uiDelegate = self
webView.navigationDelegate = self
view = webView

guard let path: String = Bundle.main.path(forResource: "index", ofType: "html") else {
    fatalError()
}
let myURL = URL(fileURLWithPath: path, isDirectory: false)
self.webView.loadFileURL(myURL, allowingReadAccessTo: myURL)

index.html

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Sample</title>
</head>
<body>
<input type="file" name="example" accept="image/jpeg,image/png">
</body>
</html>

Out of process UI (such as the image picker) is not guaranteed to support your appearance customizations.

However, the text color can be changed with tintColor.

AppDelegate.swift

UINavigationBar.appearance().tintColor = .systemPink

index.html

<input type="file" name="example" accept="image/jpeg,image/png" multiple/>
