In the Starting an iOS session documentation topic the [[MQALogger defaultSettings] setReportOnDoubleSlideEnabled:false] method is mentioned, however the library does not have such a method.
Is there a library update the contains this method, or did I miss something?
Note that the feature you are trying to enable is deprecated (meaning that is no longer maintained and could very well fail to work), and should likely not be used.
It might as well be that you are indeed using an MQA version that has this feature removed.
