The Feel of Motion

How an animation accelerates and settles shapes its personality. The timing curve decides whether motion feels snappy, smooth, or bouncy.

Linear Is Constant

A linear curve moves at one steady speed start to finish. It can feel mechanical, so it suits progress bars more than UI.

.animation(.linear, value: x)

Ease In and Out

The easeInOut curve starts slow, speeds up, then slows to a gentle stop, the most natural choice for most UI.

.animation(.easeInOut, value: x)

Ease In vs Ease Out

Use easeIn to start gently and easeOut to stop gently, picking which end of the motion feels softer.

Meet Springs

A spring animation models real physics, overshooting slightly and settling, which feels lively and responsive.

.animation(.spring, value: x)

Tune the Bounce

The bounce parameter sets how springy the motion is. Zero is smooth; higher values add a playful overshoot.

.spring(duration: 0.5, bounce: 0.3)

Response and Damping

Springs can also be tuned with response for speed and damping for how quickly the bounce dies out.

.interpolatingSpring(
    stiffness: 170, damping: 15)

Custom Bezier Curves

For full control, timingCurve lets you define a custom bezier with your own control points and duration.

.timingCurve(0.2, 0.8, 0.2, 1,
    duration: 0.5)

Add a Delay

Chain .delay onto any animation to wait before it begins, perfect for staggering several elements.

.animation(.spring.delay(0.1), value: x)

Repeat the Motion

Use repeatForever or repeatCount to loop an animation, ideal for pulsing dots and loading hints.

.easeInOut.repeatForever(
    autoreverses: true)

Speed It Up or Down

The .speed modifier scales an animation faster or slower without rewriting its curve or duration.

.animation(.default.speed(2), value: x)

Quick Check

Which curve gives the most natural everyday UI motion?

Recap: Curves and Springs

You explored timing curves from linear to easeInOut, lively springs with bounce, custom beziers, delays, and repeats. Now your motion has personality. 🚀
