我正在使用PhoneGap Build构建iOS应用程序进行编译。我以前曾使用PGB为iOS进行编译，但是由于某些原因，构建失败并显示以下错误消息：
Check dependencies
The “Swift Language Version” (SWIFT_VERSION) build setting must be set to a supported value
for targets which use Swift. Supported values are: 3.0, 4.0, 4.2. This setting can be set in
the build settings editor.

我对cordova和phonegap还是比较陌生，我不知道是什么导致了错误。我曾尝试对其进行研究，但找不到对我的情况有所帮助的任何东西。我怀疑它可能与某个插件有关，但是我不确定是哪个插件导致了该问题或如何解决该问题。
我的config.xml是
