title: Binary operator '+' cannot be applied to two CGFloat operands?
body: <p>Coding in Swift and get the above error...</p>
  
  <p>Is the message masking something else OR can you really not add two CGFloat operands? If not, why (on earth) not?</p>
  
  <h1>EDIT</h1>
  
  <p>There is nothing special in the code I am trying to do; what is interesting is that the above error message, VERBATIM, is what the Swift assistant compiler tells me (underlining my code with red squiggly lines).</p>
