ios - Swift push segue without trigger -


i trying push view controller without button or action.. thing is, in view1 check if user logged in, , if not, should go view2(login/signup) controller..

i have tried with: 

import foundation  import uikit import spritekit import parse  class mainmenu: uiviewcontroller {    override func viewdidload() {     super.viewdidload()     checkifloggedin()   }    func checkifloggedin() {     var currentuser = pfuser.currentuser()     println("\(currentuser)")     if currentuser != nil {       println("user logged in, , stays on main menu")     }     else {       println("user goes login page")       //self.storyboard!.instantiateviewcontrollerwithidentifier("loginpage") as! loginpage       //self.performseguewithidentifier("needtologin", sender: self)     }   }    override func prefersstatusbarhidden() -> bool {     return true   }
