‘windows’ was deprecated in iOS 15.0: Use UIWindowScene.windows on a relevant window scene instead 오류 해결하기

개발을 하면서

guard let window = UIApplication.shared.windows.first(where: { $0.isKeyWindow }) else { return }

이러한 window에 관한 코드를 작성하는데

windows' was deprecated in iOS 15.0: Use UIWindowScene.windows on a relevant window scene instead

이런 경고 표시 창이 떴다면,

let scenes = UIApplication.shared.connectedScenes
let windowScene = scenes.first as? UIWindowScene
guard let window = windowScene?.windows.first(where: { $0.isKeyWindow }) else { return }

코드를 이렇게 바꿔서 작성해주면 된다.
