title: How to compile xcode project?
body: <p>I have an Xcode project for an iOS app as a legacy project. Full source code, it works 100%. I need to publish it to AppStore. But I have never used Xcode, macOS or done any ios app development related stuff and I have problems to compile it and not sure if I am doing it correctly.</p>
  
  <p>I tried "Product->Run" and "Product->Build". I always get "Build Failed" and some errors. In the navbar, I choose "iPhone 7 (10.3.1)" and some other versions as well. Errors I get - </p>

  <p>But as I mentioned, it is a finished app and I don't feel I should be making any changes to the code and not to a 3rd party code (SDWebImage).</p>
  
  <p>I want to compile this project so I get the .ipa file. What is the step-by-step approach to getting a .ipa file from source code?</p>
