My application is configured to use
JsConfig.TimeSpanHandler = TimeSpanHandler.StandardFormat and I have a DTO that returns an object that contains a TimeSpan property. The TimeSpan property is nil when calling this DTO from the Swift client because only the Xsd:Duration format is currently supported. I was able to workaround this issue with the Java client but I cannot apply a similar workaround for the Swift client as I do not want to modify the JsonServiceClient.swift.
Do you plan to support the TimeSpan .Net format in the Swift client? I may be able to send you a pull request for this if you want.
