-## Step 2: Build iOS App: CaffeSimple with Xcode
-
- - For CaffeSimple to run, you need a pre-trained LeNet on MNIST caffe model and the weight file.
-Follow the instructions in [Training LeNet on MNIST with Caffe](http://caffe.berkeleyvision.org/gathered/examples/mnist.html) to train your LeNet Model on MNIST. Then copy the model file `caffe/examples/mnist/lenet.prototxt` and the trained weight file `caffe/examples/mnist/lenet_iter_10000.caffemodel` to CaffeSimple app directory.
-
-```
-$ ./tools/prototxt2bin.py $CAFFE/examples/mnist/lenet.prototxt
-$ cp $CAFFE/examples/mnist/lenet.protobin \
-     $CAFFE_MOBILE/examples/ios/simple/CaffeSimple/data/net.protobin
-$ cp $CAFFE/examples/mnist/lenet_iter_10000.caffemodel \
-     $CAFFE_MOBILE/examples/ios/simple/CaffeSimple/data/weight.caffemodel
-```
-
- - Check the batch size setting in net.prototxt, set it to `1` if needed.
-
- - Load the Xcode project inside the `$CAFFE_MOBILE/examples/ios/simple/` folder, change build target to one of your "iOS Simulators" , and press Command-R to build and run it on the simulator.
