title: How can I set the icon for a Mac Application in Xcode?
body: <p>I have been learning a lot about writing Objective-C code and designing in Interface Builder and I wanted to set icons for my simple programs.</p>
  
  <p>I added the same JPG to all the size fields in Icon Composer and got an ICNS, but I couldn't figure out how to add it to the project.</p>
  
  <p>Thank you in advance.</p>
