Swift Loop

A Figma plugin for creating iterated and grid-arrayed graphics. Drag sliders, watch shapes multiply in real time.

Swift Loop is a modernized fork of Looper by Kuldar Kalvik, with later contributions from the girafic fork. Rebuilt on Figma's current Plugin API with a formula-first engine, live slider preview, and a cols × rows grid mode.

Install (no build needed)

1. Download the latest swift-loop-vX.Y.Z.zip from the Releases page
2. Unzip anywhere
3. In Figma desktop → Plugins → Development → Import plugin from manifest… → pick manifest.json

Usage

1. Select a Vector, Shape, Text, or Group
2. Open Swift Loop
3. Set columns and rows (or leave rows=1 for a linear chain)
4. Adjust X, Y, rotation, scale, opacity — preview updates as you drag
5. Open Modulation to add randomness or sinusoidal waves
6. Apply a preset or browse the Library for community-contributed patterns
7. Click Generate to commit

Formula Library

Swift Loop ships with a Library of formula patterns (radial, spiral, phyllotaxis, hex, wave, more) browsable from the Presets section. Each pattern is a small JSON file in library/ with a procedural SVG thumbnail rendered from its own formulas.

Contribute a pattern: see CONTRIBUTING.md. One JSON file + one PR.

Custom formulas

Click the fx pill in the top-right to switch into formula mode. Each property becomes a math expression you can edit freely:

x = cos(t * TAU) * 200
y = sin(t * TAU) * 200
rotation = t * 360

Available scope: i, n, c, r, cols, rows, t, tx, ty, w, h, seed Available functions: sin, cos, tan, asin, acos, atan, atan2, sqrt, pow, exp, log, abs, min, max, floor, ceil, round, rand() Constants: PI, E, TAU

Install from source

git clone https://github.com/swiftner/swift-loop.git
cd swift-loop
bun install
bun run build

Then same Figma import step.
