Use time to determine outcome (SWIFT)

I'm practicing on my own and I'm having trouble making my code work. I attempted to use if statements but I know that if statements are "lazy" and once one of the conditions is true it will not execute the rest. Can someone help find a more efficient way of doing this. I included my code below.

Thank you.

let date = NSDate()

let calendar = NSCalendar.currentCalendar()

let components = calendar.components([.Day , .Month , .Year], fromDate: date)

let year = components.year

let month = components.month

let day = components.day

let componentFHM = calendar.components([ .Hour, .Minute, .Second], fromDate: date)

let hour = componentFHM.hour

let minute = componentFHM.minute

if hour >= 17{

  if minute >= 0{

    if minute >= 30{

        if hour <= 19{

            if minute >= 0{

                if minute <= 40{
         // Enter print hello world
            print("Helloworld") }}}}}}else{
       //enter print Hello Mac
         print("Hello Mac")}
