| OpenCV 3.4.2 Open Source Computer Vision

Installation in iOS

## Required Packages

- CMake 2.8.8 or higher
- Xcode 4.2 or higher

### Getting the Cutting-edge OpenCV from Git Repository

Launch GIT client and clone OpenCV repository from here

In MacOS it can be done using the following command in Terminal:

cd ~/<my_working _directory>
git clone https://github.com/opencv/opencv.git

## Building OpenCV from Source, using CMake and Command Line

1. Make symbolic link for Xcode to let OpenCV build scripts find the compiler, header files etc.
   cd /
   sudo ln -s /Applications/Xcode.app/Contents/Developer Developer
2. Build OpenCV framework:
   cd ~/<my_working_directory>
   python opencv/platforms/ios/build_framework.py ios

If everything's fine, a few minutes later you will get /<my_working_directory>/ios/opencv2.framework. You can add this framework to your Xcode projects.
