The longer I work with Swift, the more I realize how underrated let is.

A lot of issues around:

• unpredictable state
• accidental mutations
• SwiftUI update behavior
• concurrency bugs

usually trace back to weak immutability practices.

Early on, I treated var vs let as beginner syntax.

Now it feels more like an architectural decision.

Curious how other iOS developers approach immutability in production apps.

I recently wrote a deeper breakdown on this while starting a Swift Mastery series:
