Adding up to my conclusions after cleaning up the project and starting the SDK integration from point aero:
- the SDK walkthrough is not complete, but with minor modifications I have finally managed to get Wwise initialized and accessible in swift;
- the configuration page states that for basic operation four libraries are required: memory manager, streaming manager, sound engineer and music engine, however I got an error related to the memory manager sinking for communication functionality. Therefore communication library was required as well.
- the initialization page is clear enough, except the low level IO part and streaming device initialization which refers to the samples. And the latter contains a lot of interconnected files. For now I decided to skip this part. Hope it's just an advanced functionality that I do not need now.
