title: UILexicon in Objective-C
body: <p>How do you use UILexicon in Objective-C? I find the documentation Apple provides is extremely unhelpful.</p>
  
  <p>What does it do? Does it return a dictionary or proper spellings of words? Or do I provide a word like "hellllo" and it matches it with the proper spelling "Hello" and returns that as a string?</p>
  
  <p>Any help would be appreciated.</p>

  <p>Here's my error report, but obviously I'll have errors because I'm completely guessing how to use the function, no clue what goes inside the block statement (because the docs (at the time) don't say! (Beta 4 docs)) Hahahah!
