Swift Charts now runs in the browser.

Write Chart { BarMark(x: .value(...), y: .value(...)) } in MiniSwift Studio and watch it render live — bars, lines, scatter, pie, multi-series with legends. No Mac. No Xcode. No server.

The wild part: it's a Swift compiler hand-written in C → WebAssembly, and the charts are drawn on a <canvas> straight from the compiled UI tree. 100% client-side.

Build a UV-index-style area chart inspired by iOS Weather. Uses 𝐴𝑟𝑒𝑎𝑀𝑎𝑟𝑘 and 𝐿𝑖𝑛𝑒𝑀𝑎𝑟𝑘 with linear gradients, cardinal interpolation, and a custom 𝑅𝑒𝑐𝑡𝑎𝑛𝑔𝑙𝑒𝑀𝑎𝑟𝑘 mask for a dimming layer.

I'm adding a new chart and hit a strange Swift Charts issue.

If the Y-axis data is all zeros then the Y-axis gets flipped!

Specifying a chartYScale seems to be the solution.

.chartYScale(domain: 0...(yValues.last ?? 1), type: .linear)

Just published a deep dive on how I built interactive timelines in Viatza using Swift Charts — medicine bars, symptom lanes, tap + drag selection, and a few SwiftUI surprises along the way.

If you’re working with charts or health data, hope it helps 🌿
Comments welcome.

I wrote a blog post about the improvements I made to @PleaseDontRain based on feedback from my WWDC accessibility lab.

I didn't expect it to involve time zones! ⏰

Beyond Linear: Using MeshGradient in Swift Charts

I just wrote an addendum to the blog post I wrote recently about struggling to find an answer to a Swift Charts problem I was having.

It was a night and day difference with the next issue I encountered.

#SwiftCharts

Swift Charts lets you manually choose what color is used for each category in the legend but it doesn't appear that you can manually choose what shapes appear in it.

I made my own legend to use when differentiate without color is active.

I think that I'm done with this new feature!

I created an example in my accessibility settings for @PleaseDontRain to show how I'm differentiating without color for my bar charts.

Really happy with how this turned out!
