so per comments, custom collection view cell :

class customecell: uicollectionviewcell {

@ibaction func tweetbuttonpressed() {      let cvc = slcomposeviewcontroller(forservicetype:slservicetypetwitter)     if let c = cvc {         c.setinitialtext("test tweet ios app")          self.parentviewcontroller?.presentviewcontroller(c, animated: true, completion: nil)     }  } 

}

create extension.swift file :

import uikit

extension uiview {

var parentviewcontroller: uiviewcontroller? {      var parentresponder: uiresponder? = self      while parentresponder != nil {         parentresponder = parentresponder!.nextresponder()          if let viewcontroller = parentresponder as? uiviewcontroller {              return viewcontroller          }      }      return nil  } 

}

this working me. best!
