What it does
Swift Charts is an agent skill from dpearson2699/swift-ios-skills. Implement, review, or improve data visualizations using Swift Charts. Use when building bar, line, area, point, pie, donut, or iOS 26 3D charts; when adding chart selection, scrolling, annotations, axes, scales, legends, or foregroundStyle grouping; when plotting functions with BarPlot, LinePlot, AreaPlot, PointPlot, Chart3D, or SurfacePlot; or when creating heat maps, Gantt charts, grouped bars, sparklines, threshold lines, or spatial visualizations.
Its SKILL.md is about 3.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/charts-patterns.md`).
It sits in Data & Analytics, covering Data visualization, iOS development and Accessibility. It works with iOS. The repository describes itself as: Agent Skills for iOS 26+, Swift 6.3, SwiftUI, and modern Apple frameworks.
When your agent uses it
- IOS 26 3D charts
- Adding chart selection
- ForegroundStyle grouping
- Plotting functions with BarPlot
Example prompts
- “/swift-charts”
Workflow steps
11 steps, taken from the step headings in SKILL.md.
- Build a new chart
- Review existing chart code
- Missing series parameter for multi-line charts
- Too many SectorMark slices
- Missing scale domain when zero-baseline matters
- Static foregroundStyle overriding data encoding
- Individual marks for 10,000+ data points
- Fixed chart height breaking Dynamic Type
- KeyPath modifier after value modifier on vectorized plots
- Missing accessibility labels
- Treating angle selection as category selection
What it can do on your machine
Read from SKILL.md and the folder at commit 8d90fd1. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are swift).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
sosumi.ai
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Swift Charts loads about 3.8k tokens when it runs, and up to ~10k if it reads all its reference files. Until then it costs about 117 tokens; SKILL.md has 657 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 657 words (~3,835 tokens).
“Build data visualizations with Swift Charts targeting iOS 26+. Compose marks inside Chart or Chart3D, configure axes and scales with view modifiers, and use vectorized plots or 3D plots when the data calls for them.”
