title: IOS: AOT ahead of time, what is it?
body: <p>I have read an article from Xamarin, and came across a particular computer science word : Ahead of Time.
  According to some google search result, this AOT does not allow for code generation during run time.
  Does it mean, it does not support dynamic stuff? </p>
  
  <p>I know this question may stupid and I have 0 knowledge in IOS, hopefully can get some answer from here. thanks</p>
