Modern iOS Performance Myths

Swift Academy is back for Season 3.

This two‑part deep dive tackles iOS performance misconceptions with real‑world engineering expertise. Guests Artem Mirzabekian and Bogdan Poplauschi share hard‑won lessons from years building high‑performance apps.

What's challenged:

• What "performant" actually means in 2026 (it's not just FPS)
• Why technically fast apps can still feel slow
• Whether SwiftUI simplifies performance or hides its costs
• Which SwiftUI patterns break at scale
• Is Environment becoming the new Service Locator?
• What really consumes your 16.67ms frame budget
• Why Instruments doesn't always tell the full story
• Concurrency vs Parallelism — and why it matters

No micro‑optimizations. No benchmark numbers. Just mental models that make you a better engineer.
