Thanks Sean! Great video. Just try to talk slower 🙂

Thanks. It’s clear understanding. You nailed it

func yearAlbumReleased(name: String) -> Int? {
   if name == “Taylor Swift” { return 2006 }
   if name == “Fearless” { return 2008 }
   if name == “Speak Now” { return 2010 }
   if name == “Red” { return 2012 }
   if name == “1989” { return 2014 }
   return nil 
}

How to use IF LET here ….?

Thanks for clearing up guard statements, Sean. These are great videos and very easy to follow along with, but I’ll admit I had to turn the speed to 0.75 to keep up!

Expecting more Thanks

in line 10 you write if let number = optionalNumber
does it means that let nuber = optinalNumber is a bollean?

awesome! I think I finally get the difference between ways to unwrap, nice and concise. I think I’m even getting used to your delivery speed. Kinda starting to like it.

Great Job @Sean! 🙂

Thanks. This is a quality tutorial. Keep up the good work!

Thank you! I think i finally understand how to handle optionals.

How about when u declare variable like this: var number: Int!
this means: “I am sure 100% that number variable will have value?”

Here’s one: Let’s say I have a wrapper that contains a boolean called isHeader… How the hell I can write below code without force wrapper var and be conformed with lint good practices

if wrapper?.isHeader == nil || !(wrapper?.isHeader)! { return .zero }

return CGSize(10)

Tried something like
guard let myWrapper = wrapper, myWrapper.isHeader else { return .zero } but after got lint warning Unused Optional Binding Violation: Prefer `!= nil` over `let _ =` (unused_optional_binding)

Anu suggestion?

Great tutorial. There is one more technique to unwrap an optional. Nil-Coalescing Operator: let a = b ?? c

Questions about unwrapping optionals? Leave a comment and I’m happy to help!
