[Swift] App BadgeCount 변경하기

# [Swift] App BadgeCount 변경하기

안녕하세요 __물먹고하자__ 입니다 :)
업무 급한일들 마무리 해놓고, 설전까지 코드 정리하다가 __BadgeCount API deprecated__ 된 걸
확인하고 변경했던 부분 공유드립니다.

간단하니 바로 시작!

``` swift
// 카운트 갱신
let dzBadgeCount:Int = '갱신할 카운트 정보(Int)'

if #available(iOS 16.0, *) {
    UNUserNotificationCenter.current().setBadgeCount(dzBadgeCount)
} else {
    UIApplication.shared.applicationIconBadgeNumber = dzBadgeCount
}

```

## 마무리
Objc 소스 부분이였는데, Swift로 변경하기 경고로 deprecated 되었다고 떠서 알게되었습니다.
간단한 부분이지만, 최소 버전이 iOS 15.0 이상이여서 분기처리는 추가하였습니다.

오늘은 이만~

즐거운 코딩 되게요.

끝.
