You can do date arithmetic by using NSDateComponents  For example   import Foundation  let comps   NSDateComponents    comps minute   5  let cal   NSCalendar currentCalendar    let r   cal dateByAddingComponents comps  toDate  NSDate    options  nil    It is what you see when you try it in playground

Two approaches    Use Calendar and date byAdding to wrappingComponents    E g   in Swift 3 and later   let calendar   Calendar current let date   calendar date byAdding   minute  value  5  to  startDate   Just use   operator  see          to add a TimeInterval  i e  a certain number of seconds   E g  to add five minutes  you can   let date   startDate   5   60    Note  the order is specific here  The date on the left side of the   and the seconds on the right side    You can also use addingTimeInterval  if you   d prefer   let date   startDate addingTimeInterval 5   60     Bottom line    addingTimeInterval is easiest for simple scenarios  but if you ever want to add larger units  e g   days  months  etc    you would likely want to use the calendrical calculations because those adjust for daylight savings  whereas addingTimeInterval doesn   t     For Swift 2 renditions  see the previous revision of this answer

You can use Calendar s method   func date byAdding component  Calendar Component  value  Int  to date  Date  wrappingComponents  Bool   default  - gt  Date    to add any Calendar Component to any Date  You can create a Date extension to add x minutes to your UIDatePicker s date   Xcode 8 and Xcode 9     Swift 3 0 and Swift 4 0  extension Date       func adding minutes  Int  - gt  Date           return Calendar current date byAdding   minute  value  minutes  to  self               Then you can just use the extension method to add minutes to the sender  UIDatePicker    let section1   sender date adding minutes  5  let section2   sender date adding minutes  10      Playground testing   Date   adding minutes  10        Jun 14  2016  5 31 PM

Save this little extension   extension Int     var seconds  Int       return self      var minutes  Int       return self seconds   60      var hours  Int       return self minutes   60      var days  Int       return self hours   24      var weeks  Int       return self days   7      var months  Int       return self weeks   4      var years  Int       return self months   12        Then use it intuitively like   let threeDaysLater   TimeInterval 3 days  date addingTimeInterval threeDaysLater
