Trade Diary란?

Team Project로 만들어짐.

My Job: NewPostController, TimeHandler

Code

Time Handler

 timeFormatter.locale = Locale(identifier: "en_US_POSIX")
 timeFormatter.dateFormat = "h:mm a"
 timeFormatter.amSymbol = "am"
 timeFormatter.pmSymbol = "pm"
 let stringTime = timeFormatter.string(from: currentTime)
 return stringTime
}
func getCurrentDate() -> String {
 let currentDate = Date()

 dateFormatter.locale = Locale(identifier: "en_US_POSIX")
 dateFormatter.dateFormat = "EEEE / MMMM dd / yyyy"
