set segue identifier in storyboard, first of all. find field can set identifier after click segue link.

view controller call next viewcontroller

func showsomeviewcontroller() {     self.performseguewithidentifier("testcontainer", sender: self); }  override func prepareforsegue(segue: uistoryboardsegue, sender: anyobject?) {      if (segue.identifier == "testcontainer")     {         let vc: testviewcontroller = segue.destinationviewcontroller as! testviewcontroller         vc.tmpstring = "say ho"     }  } 

and testviewcontroller

class testviewcontroller: uiviewcontroller {  var tmpstring: string!  override func viewdidload() {     super.viewdidload()      // additional setup after loading view. } }
