Actually i am a beginner in swift and Deeplab V3. I literally don't know how to integrate deeplab on Xcode. I only just want to use tensorflow trained example model for semantic segmentation in ios.

Go through the above mentioned link which implements a COREML model used for Segmentation. Convert your Tensorflow model into Coreml model using standard conversion tools. We have tested it once. And so confident enough that it will work.
