I will try or ask my friend to do.

That would be awesome mate! We’ve been trying to withot success, but we did come across some good resources. “For larger models — and especially for deep learning — you want to use the GPU instead. And on iOS that means using Metal. You’ll still do the training with TensorFlow on your Mac — or for big models on a Linux box with a fat GPU or even in the cloud — but the inference code that runs on iOS uses Metal instead of the TensorFlow library.” For ex he provides the steps in order to use Metal http://machinethink.net/blog/tensorflow-on-ios/ 
Also this guy manage to do it, presenting the caveats too: http://blog.stratospark.com/creating-a-deep-learning-ios-app-with-keras-and-tensorflow.html
