🔍Who's faster -- let or var?
After running 1 billion iterations, let turned out to be ~0.3% faster than var.
Sure, it’s not game-changing — but it’s measurable.
💡 Pro tip: use let by default to optimize both clarity and performance.

🚀 Swift Tip #5 Optional binding = safe unwrapping without crashing.
No ! no risk.

use(itemName)
}
Use it like you’d open a chest only if treasure’s inside 🧱
🚀 Swift Tip #3
Swift gives you 4 primitive types to build anything:
Int → Espresso of numbers ☕ health = 100
Double → Creamy floats 🥛 price = 3.14
Bool → Cookie or no cookie? 🍪 isLoggedIn = true
String → Friendly messages 📣 name = "Player"
Simple, powerful.
