1:Swift4.0后第三方語法報錯撤蚊，想引用swift3.2
解決方法
在pods->targets->bass combined->swift compiler-languege
這里可以設(shè)置第三方使用的swift版本
2:The use of Swift 3 @objc inference in Swift 4 mode is deprecated. Please address deprecated @objc inference warnings, test your code with “Use of deprecated Swift 3 @objc inference” logging enabled, and then disable inference by changing the "Swift 3 @objc Inference" build setting to "Default" for the "Moya" target.
