42분간은 1초에서 3초간격으로 로깅이 되었고, 맥북이 잠자기모드로 전환된건지 슬립모드로 전환된건지는 모르겠지만

호출간격 시간이었던 1초간격은 무시되었고, 

18분 뒤 호출되었다. 

그리고 다음 호출로 15분 뒤 호출, 15분 뒤 호출, 17분뒤 호출, 16분뒤 호출 , 17분 뒤 호출 후 서비스가 죽었다.

슬립모드에 들어가서 그런건가?

[테스트 코드]

백그라운드에서 1초간격으로 호출 테스트 코드

print("################ startBackgroundTask")
DispatchQueue.global(qos: .background).asyncAfter(deadline: .now() + 3) { //global(qos: .utility)
        let runLoop = RunLoop.current
        timer = Timer.scheduledTimer(withTimeInterval: 1, repeats: true) { timer in

//                    DispatchQueue.main.async {
                checkTask()
//                    }
        }

    // Run the timer on the current run loop
//            RunLoop.current.add(timer!, forMode: .common)
    runLoop.add(timer!, forMode: .default)
    runLoop.run()

func checkTask() {
	remaing = "remaing--> (content[3])"
    
    print("(nowDate) :percent--> (content[2])%")

}

@State private var remaing = ""
@State var timer: Timer? 

@Environment(.colorScheme) var colorScheme
@Environment(.scenePhase) var scenePhase

var body: some View {
    VStack {
                Text(remaing)
    }
}

[오류 해결]

DispatchQueue.main.async 로 감싸주고 다시 테스트를 진행중이다.

DispatchQueue.main.async {
	checkTask()
}

멈추지 않고 잘 된다면, 반쪽자리 프로그램에서 벗어날 수 있을 것 같다.
