Display a label depending on a date in swift
<p>Lets say i want to display a string depending on which date it is. 
For example if it is 2016-12-24 i want the string "Merry Christmas" to be displayed or if it is 2017-01-01 i want the text "Happy New Year". </p>

<p>This is what i got so far but i don't know how to add a string to it and hook it up to a label.</p>

<pre><code>    let now = NSDate()
print(now)
now.timeIntervalSinceReferenceDate

// March 10, 1876 was 3,938,698,800 seconds before the third millennium (January 1, 2001 midnight UTC)
let firstLandPhoneCallDate = NSDate(timeIntervalSinceReferenceDate: -3_938_698_800.0)

// April 3, 1973 was 875,646,000 seconds before the third millennium
let firstCellPhoneCallDate = NSDate(timeIntervalSinceReferenceDate: -875_646_000.0)

// January 9, 2007, 18:00 UTC was 190,058,400 seconds after the third millennium
let iPhoneAnnouncementDate = NSDate(timeIntervalSinceReferenceDate: 190_058_400.0)

// January 27, 2010, 18:00 UTC was 286,308,000 seconds after the third millennium
let iPadAnnouncementDate = NSDate(timeIntervalSinceReferenceDate: 286_308_000.0)
</code></pre>
