Tested with Swift 4 Getting the Current Date and Time You can get the current date and time as simply as this  let currentDateTime   Date    However  Date is a 64-bit floating point number measuring the number of seconds since the reference date of January 1  2001 at 00 00 00 UTC  I can see that number for the current datetime by using Date   timeIntervalSinceReferenceDate  At the time of this writing  it returned 497626515 185066  probably not exactly what you are looking for  Keep reading  Creating Another Date and Time Method 1 If you know the number of seconds before or after the reference date  you can use that  let someOtherDateTime   Date timeIntervalSinceReferenceDate  -123456789 0     Feb 2  1997  10 26 AM  Method 2 Of course  it would be easier to use things like years  months  days and hours  rather than relative seconds  to make a Date  For this you can use DateComponents to specify the components and then Calendar to create the date  The Calendar gives the Date context  Otherwise  how would it know what time zone or calendar to express it in     Specify date components var dateComponents   DateComponents   dateComponents year   1980 dateComponents month   7 dateComponents day   11 dateComponents timeZone   TimeZone abbreviation   quot JST quot      Japan Standard Time dateComponents hour   8 dateComponents minute   34     Create date from components let userCalendar   Calendar current    user calendar let someDateTime   userCalendar date from  dateComponents   Other time zone abbreviations can be found here  If you leave that blank  then the default is to use the user s time zone  Method 3 The most succinct way  but not necessarily the best  could be to use DateFormatter  let formatter   DateFormatter   formatter dateFormat    quot yyyy MM dd HH mm quot  let someDateTime   formatter date from   quot 2016 10 08 22 31 quot    The Unicode technical standards show other formats that DateFormatter supports  Displaying the Date and Time Method 1 If you want to just display certain components of the date or time you can use CalendarUnit to specify the components that you want to extract from Date     get the current date and time let currentDateTime   Date       get the user s calendar let userCalendar   Calendar current     choose which date and time components are needed let requestedComponents  Set lt Calendar Component gt           year       month       day       hour       minute       second       get the components let dateTimeComponents   userCalendar dateComponents requestedComponents  from  currentDateTime      now the components are available dateTimeComponents year      2016 dateTimeComponents month     10 dateTimeComponents day       8 dateTimeComponents hour      22 dateTimeComponents minute    42 dateTimeComponents second    17  See this answer also  Method 2 Method 1 gave you the components  but it would be a lot of work to format those numbers for every style  language  and region  And you don t need to  This has already been done for you with the DateFormatter class     get the current date and time let currentDateTime   Date       initialize the date formatter and set the style let formatter   DateFormatter   formatter timeStyle    medium formatter dateStyle    long     get the date time String from the date object formatter string from  currentDateTime     October 8  2016 at 10 48 53 PM  Here is a continuation of the above code that shows more formatting options      quot 10 8 16  10 52 PM quot  formatter timeStyle    short formatter dateStyle    short formatter string from  currentDateTime       quot Oct 8  2016  10 52 30 PM quot  formatter timeStyle    medium formatter dateStyle    medium formatter string from  currentDateTime       quot October 8  2016 at 10 52 30 PM GMT 8 quot  formatter timeStyle    long formatter dateStyle    long formatter string from  currentDateTime       quot October 8  2016 quot  formatter timeStyle    none formatter dateStyle    long formatter string from  currentDateTime       quot 10 52 30 PM quot  formatter timeStyle    medium formatter dateStyle    none formatter string from  currentDateTime   Keep in mind  though  that this is for English with the region set to the US  For other languages and regions the formatting will look different  Further study  How to work with dates and times in Swift 3  part 1  Dates  Calendars  and DateComponents How to work with dates and times in Swift 3  part 2  DateFormatter How to work with dates and times in Swift 3  part 3  Date arithmetic

Swift makes it really easy to create and use extensions   I create a sharedCode swift file and put enums  extensions  and other fun stuff in it   I created a NSDate extension to add some typical functionality which is laborious and ugly to type over and over again   extension NSDate       func hour   - gt  Int                 Get Hour         let calendar   NSCalendar currentCalendar           let components   calendar components  Hour  fromDate  self          let hour   components hour            Return Hour         return hour             func minute   - gt  Int                 Get Minute         let calendar   NSCalendar currentCalendar           let components   calendar components  Minute  fromDate  self          let minute   components minute            Return Minute         return minute            func toShortTimeString   - gt  String                 Get Short Time String         let formatter   NSDateFormatter           formatter timeStyle    ShortStyle         let timeString   formatter stringFromDate self             Return Short Time String         return timeString           using this extension you can now do something like             Get Current Date         let currentDate   NSDate              Test Extensions in Log         NSLog   Current Hour     currentDate hour      Current Minute     currentDate minute      Current Short Time String     currentDate toShortTimeString         Which for 11 51 AM would write out       Current Hour   11   Current Minute   51   Current Short Time String   11 51 AM
