Xcode 仅在存档时发生iOS swift编译错误

我得到以下错误

AppDelegate.swift:152:30:“（appToken:String！）->SKTSettings”不是 可转换为“（appToken:String！）->SKTSettings！'

AppDelegate.swift:167:23:'（writeKey:String！）-> SEGAnalyticsConfiguration“不能转换为”（writeKey:String！）->SEGAnalyticsConfiguration！'

冒犯的台词

让smoochSettings=SKTSettings（appToken:“xxxxx”） let config=SEGAnalyticsConfiguration（写入键：“xxxx”）

任何线索，我都不明白

关于代码的更多上下文

更新将SDK更新为5.0.1版将解决此问题

如前所述，在更新到XCode 8后，Swift编译器无法正确确定值是否为可选值。将nullability说明符添加到Smooch头文件应该可以解决此问题。带有nullability说明符的生成正在进行中，应该很快发布
