title: Difference between Build Phases -> Link Binary with Libraries or Build Settings -> Linker Flags
body: <p>What's the difference between Build Phases -> Link Binary with Libraries or Build Settings -> Linker Flags?</p>
  
  <p>The former does not seem to allow you to specify between Debug vs Release, and the frameworks specified within it also don't seem to match up with the latter.</p>
  
  <p>Note: I have checked existing posts on SO, haven't found one that answers this accurately.</p>
