Combining if Let and Where in Swift
What I like about Swift is that it feels like a natural progression when learning more of the language’s features. Case in point: I’ve known about the where
keyword for a while, and have used it plenty of times before, but just found this little ditty:
1 2 3 |
|
That will only execute the body of the statement if someThing
is not nil and someBool
is true. Before, I had thought that would’ve been two separate statements, and extra indenting. Kinda cool.
