This is a very quick one. For an app I’m working on I wanted to measure how long it took a given function to complete.
I typically don’t do this, as most functions are very fast, but this one involved a server fetch and some background processing. Anyhow, I’m getting distracted, here it is -easy as pie-:
let startTime = Date()
let endTime = Date()
let timeElapsed: Double = endTime.timeIntervalSince(startTime)
print(“Time taken \(timeElapsed) seconds”)

Just a quick update to show how to get Date Day, Month or Year in Swift 3
//Here I’m creating the calendar instance that we will operate with:
let calendar = NSCalendar.init(calendarIdentifier: NSCalendar.Identifier.gregorian)
//Now asking the calendar what month are we in today’s date:
let currentMonthInt = (calendar?.component(NSCalendar.Unit.month, from: Date()))!
//Now asking the calendar what year are we in today’s date:
let currentYearInt = (calendar?.component(NSCalendar.Unit.year, from: Date()))!
Hope this proves useful.
