I’ve been exploring and fighting this problem for a few weeks with no result and I’m really out of ideas.
I have to create a character (to import to Xcode). It is a standing in place ghost with its 'cloth' just waving in a loop (I used wind force). The only element I need to export is a waving cloth. I have prepared the simulation, baked it, exported as .mdd, imported the .mdd to obtain Shape Keys, removed irrelevant elements (incl. cloth modifier) and… I am not able to turn it into animation…
At first I presumed it’s an export problem (I posted Exporting cloth simulation to Collada results in static cloth instead of a waving one ), but then I realized that it’s not - the object is static and there is no animation.
I have proper Shape Keys but no idea how to push them run as animation. I have tried different methods to link Shape Keys to actions - still I’m not sure whether it is the core problem. I have added armature then run a script to create drivers between Shape Keys and Armature (as in https://blenderartists.org/forum/showthread.php?325838-How-to-convert-a-cloth-simulation-animation-to-keyframes and here https://blenderartists.org/forum/archive/index.php/t-261576.html and How to convert cloth simulation into mesh animation? ). I manually added an action to the Cloth, but I don’t know whether it was needed. I don’t even know if there has been established any relation between Shape Keys and any action. I have applied Object transform (scale, rotation..) - no result… This How to export a scene with Shape Keys Animation? also doesn't work for me... This one Create ghost character from a certain point in cloth simulation is also not a solution - at the end there is again cloth modified added. I see there are few threads that might be related to mine but they remain unsolved.

I export Collada and .blend to Unity for testing - there is an animation (I see frames running) but the cloth is static - not deforming.
I guess the solution must be very simple (I am a newbie) or there is a bug… Maybe anyone can help and tell me what is missing? There must be a way to export characters with animated cloth to game engines!…
I’m using Blender 2.79.
