上传到解析时Imagepicker崩溃

Question

每当我尝试将照片上传到Parse作为用户的个人资料图片时，我的应用都会崩溃。在网上查找花费的时间，但无法弄清楚。请帮忙

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) { 
    let pickedImage: UIImage = info[UIImagePickerControllerOriginalImage] as! UIImage 
     let imageData = UIImagePNGRepresentation(pickedImage) 
    let imageFile:PFFile = PFFile(data: imageData) 
    PFUser.currentUser()!.setObject(imageFile, forKey: "profile_picture") 
    PFUser.currentUser()!.saveInBackground() 
    picker.dismissViewControllerAnimated(true, completion: nil) 
}

原来这个文件太大了，我需要调整它。感谢比约恩提醒我看看堆栈跟踪
