爲什麼圖像沒有被添加到數組中？

Question

我試圖追加從解析數據庫中檢索到的圖像，但沒有任何內容被添加到UIImage數組中。如何追加檢索到的圖像？

var arrayOfFriends: [UIImage] = [] 

func getFriendPic(){ 

    var imagequery = PFQuery(className: "_User") 
    imagequery.findObjectsInBackgroundWithBlock {(objects: [AnyObject]?, error: NSError?) -> Void in 
     for object in objects!{ 
      let userPic = object["ProPic"] as! PFFile 
      userPic.getDataInBackgroundWithBlock({ (imageData: NSData?, error: NSError?) -> Void in 
       if(error == nil){ 
        let image = UIImage(data: imageData!) 
        //breakpoint placed on line below, but app crashes with array out of bounds. 
        self.arrayOfFriends.append(image!) 
        print(self.arrayOfFriends) 
       } 
       dispatch_async(dispatch_get_main_queue()) { 
        self.collectionView.reloadData() 
       } 
      }) 

     } 
    } 
}

代碼不是問題，它是Xcode，這是解決任何人有同樣的問題。 The resource could not be loaded because the App Transport Security policy requires the use of a secure connection
