I am trying to use piotr dollar's model to detect edges in IOS as suggested here. https://docs.opencv.org/3.1.0/d0/da5/tutorial_ximgproc_prediction.html

String modelFilename = "./model.yml.gz";
Ptr<StructuredEdgeDetection> pDollar = createStructuredEdgeDetection(modelFilename);
pDollar->detectEdges(image, edges);

While the above code works in my machine. (Mac OS). I am unable to make it work on IOS. I am getting the following error. 

  libc++abi.dylib: terminating with uncaught exception of type cv::Exception: OpenCV(3.4.2) 
../cv3.4/opencv-3.4.2/modules/ximgproc/src/structured_edge_detection.cpp:432: error: (-215:Assertion failed) 
modelFile.isOpened() in function 'StructuredEdgeDetectionImpl'

i have already looked at the following links.

Any pointers on how to do this.

Instead of just giving the added resource path, one has to get the path via the swift's Bundle.main.path API. 

let path = Bundle.main.path(forResource: "model.yml", ofType: "gz");

Using this api, one can get the path of the resource and use it to detect edges.
