Optionals in Swift: Handle (nil) Like a Pro!

Ever been tripped up by unexpected nil values in Swift? ?? Let’s break down optionals—a core feature that ensures safer, more predictable code!

What are optionals?

They’re Swift’s way of saying, “This variable might hold a value, or it might be nil.” No more guessing games!

Safe Unwrapping Techniques:

1. if let: Safely check and use the value inside a scope.

2. guard let: Exit early if the value is nil—cleaner code flow!

Force unwrapping (!) is like saying, “Trust me, it’s not nil.” Use sparingly—it’s a crash waiting to happen if you’re wrong!
