iOS swift 仅在归档时出现编译错误

Question

我收到以下错误

AppDelegate.swift:152:30: '(appToken: String!) -> SKTSettings' is not convertible to '(appToken: String!) -> SKTSettings!'

AppDelegate.swift:167:23: '(writeKey: String!) -> SEGAnalyticsConfiguration' is not convertible to '(writeKey: String!) -> SEGAnalyticsConfiguration!'

违规台词

let smoochSettings = SKTSettings(appToken: "xxxxx") let config = SEGAnalyticsConfiguration(writeKey: "xxxx")

任何线索，我不明白...

Answer 1

更新将 SDK 更新到版本 5.0.1 将解决此问题

如 here 所述，更新到 XCode 8 后，Swift 编译器无法正确确定这些值是否可选。将可空性说明符添加到 Smooch 头文件应该可以解决这个问题。带有可空性说明符的版本正在开发中，应该会很快发布。
