export default copilot({
    backdropColor:"rgb(30, 70, 10, 1)",
     animated: true, // Can be true or false
    overlay: 'svg', // Can be either view or svg
})(WalkThrough);

Start by reproducing the issue on iOS using the shown copilot configuration, especially backdropColor with the SVG overlay. Trace how the copilot HOC passes backdropColor to the overlay and compare the iOS result with the expected color; done means the configured backdrop color renders correctly on iOS.
