Swift is a multi-paradigm, compiled programming language introduced by Apple in 2014 at the WWDC conference. It was developed under the LLVM framework and has been influenced by languages like JavaScript, Rust, Haskell, Ruby, Python, C#, and CLU. Swift is designed to be fast, modern, safe, and interactive for building apps for Apple platforms like iOS and macOS.

Modern
Objective-C:
Swift:
if (myDelegate != nil)
{
if([myDelegate respondsToSelector: @selector(scrollViewDidScroll:)])
{
[myDelegate scrollViewDidScroll:myScrollView];
}
}
myDelegate?.scrollViewDidScroll?(myScrollView)](https://image.slidesharecdn.com/d6ccadf8-ee40-474f-87e4-28006d90012b-160808103245/85/Swift-11-320.jpg)
