Question 1

How much code can be shared across Apple platforms?

Accepted Answer

With proper architecture, 60-80% of code is shared. Models, networking, business logic, and persistence are fully reusable. UI code adapts per platform.

Question 2

Do I need separate development teams for each platform?

Accepted Answer

No. A single Swift team can build for all Apple platforms. Platform-specific expertise helps for optimization but isn't required for every developer.

Question 3

Is Vision Pro development worth investing in?

Accepted Answer

visionOS is early but growing. SwiftUI apps can run on Vision Pro with minimal changes, so building for today's platforms positions you for spatial computing.
