我收到了CGSUpdateManager警告,该警告是在用户按下"导入"后,我从NSOpenPanel完成处理程序中显示我的视图控制器大约10秒后发生的。 我触发视图控制器的代码如下所示。

func ImportCSV() {
        // Setup Panel
        let fileType: [String] = ["csv", "CSV"]
        var importPanel = NSOpenPanel()
        importPanel.title = "Import"
        importPanel.prompt = "Import"
        importPanel.allowedFileTypes = fileType
        importPanel.allowsMultipleSelection = false
        importPanel.canChooseDirectories = false
        importPanel.canCreateDirectories = false
        importPanel.canChooseFiles = true
        // Begin Panel
        importPanel.beginWithCompletionHandler { (result) -> Void in
            if result == NSFileHandlingPanelOKButton {
                self.importFileWithURL(importPanel.URL!)
            }
        }

        }

    func importFileWithURL(URL: NSURL){
                    let storyBoard = NSStoryboard(name: "Main", bundle: nil)! as NSStoryboard
                    let importFileView = storyBoard.instantiateControllerWithIdentifier("test") as ImportFileViewController
                    self.presentViewControllerAsModalWindow(importFileView)
                    importFileView.fileToImport(URL)
    }

我收到的警告是:

这个警告意味着什么,我应该担心吗?
