Your pod might have a wrong swift version, not the project settings.
您的 pod 可能有错误的 swift 版本，而不是项目设置。
To change the pod swift setting, go in the file navigator (left of the screen) to Pods (blue icon) and select the pod you're having problems with. Then go to build settings and go to Swift Language version. Select Swift 4.
要更改 pod swift 设置，请在文件导航器（屏幕左侧）中转到 Pods（蓝色图标）并选择您遇到问题的 pod。然后转到构建设置并转到 Swift 语言版本。选择 Swift 4。
