🎉 Welcome to Day 21 of #100DaysOfiOS!
In this video, we break down one of the most confusing Swift topics for beginners —Opaque Result Types, specifically some vs any, and why SwiftUI uses some View.
If you’ve ever wondered:
Why View doesn’t work as a return type
What some View actually means
When to use some vs any
…this lesson will finally make it clear.
This video explains everything from absolute basics, step by step, with simple examples and real SwiftUI context.
📘 What you’ll learn in this video:
Why returning a protocol like View fails
What any View means and when it’s used
What some View really means (the correct mental model)
Why some requires a fixed underlying type
some vs any — key differences explained clearly
Why SwiftUI prefers some View for performance
🧠 Why this matters
Understanding opaque result types removes confusion around SwiftUI, improves your Swift fundamentals, and helps you write more efficient and type-safe code.
This is a must-watch before diving deeper into SwiftUI.
