Animate Number Changes in SwiftUI

One of the most visually satisfying micro-interactions in modern iOS UI is animated number change. Finance apps, stats dashboards, fitness progress — they all use smooth numeric transitions. So naturally, “SwiftUI animate number change” is a top searched question.

Best modern method (iOS 17+)

Use .contentTransition(.numericText()).

Try it in action: Check out Crypto Profit & Loss Calculator on the App Store — it uses this animated number change effect for instant crypto profit visuals.

Older iOS (15 / 16) fallback

Just animate a SECOND number that displays.
User sees smooth change.

Bonus: animate formatting (currency)

Works with any style: percent, integer, decimal, etc.

Key takeaways

• use .contentTransition(.numericText()) on iOS 17+
• wrap number increments inside withAnimation { }
• older OS → animate a separate numeric state
