上传到Parse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照片时，我的应用都会一直崩溃。花了几个小时在网上看，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)
}

原来文件太大了，我需要扩展它。感谢Bjorn提醒我查看堆栈跟踪
