+### Liquid Glass and iOS 26+ Appearance Changes
+
+Starting with iOS 26, Apple introduced the "Liquid Glass" background effects that are applied to system bars and controls. According to Apple's documentation, "Tinting the bars interferes with background effects that the system provides."
+
+As a result, the following properties in `SafariViewControllerOptions` are **ignored** on iOS 26 and later:
+
+- `preferredBarTintColor`
+- `preferredControlTintColor`
+
+For more details, see [here](https://developer.apple.com/documentation/safariservices/sfsafariviewcontroller).
