Emerge's Bits & Bytes: February 2024

We'd love to hear your thoughts (4 questions, all optional, may receive swag 😉) on the current mobile landscape and how Emerge can help you in your role. Any responses are greatly appreciated 🙏

What we're building

Snapshot Accessibility Tooling

With one line, you can get snapshots of accessibility elements in your previews (docs).

emergeAccessibility() uses AccessibilitySnapshot to visualize accessibility elements on your preview.

This is our second major accessibility release after our open-source method to get Xcode accessibility audits on every preview. We’re very excited for even more accessibility updates to help improve an underserved area of mobile.

"If you use SwiftUI it’s a no-brainer compared to other snapshot testing approaches." - Eric Horacek, iOS @ OpenAI.

Couldn’t have said it better ourselves 🙂

ETTrace support for visionOS & tvOS

ETTrace can now profile tvOS and visionOS apps right from the simulator or via the developer strap.
