macSVG is a MIT-licensed open-source macOS app for designing HTML5 SVG 1.1 (Scalable Vector Graphics) art and animation. macSVG can produce dynamic, high-quality graphics and animation for HTML5 web views that work on most major desktop and mobile platforms, including iOS, Android, macOS, Microsoft Windows and Linux. macSVG uses the standard macOS WebKit framework for interactive editing and rendering of SVG documents, in addition to several Cocoa plug-in bundles for editing SVG elements and attributes. Apple’s free Xcode system is required to build the macOS application from the source code. Most of the application source code is written in Objective-C language, but a Swift language target has been added recently for a plug-in editor bundle. To build macSVG.app, open "macSVG.xcworkspace" in Xcode, set the build target to "macSVG Debug", build and run.

...There's also an example project. In the example, you can swipe horizontally and vertically to try various shimmering parameters, or tap to start or stop shimmering. (To build the example locally, you'll need to open FBShimmering.xcworkpace rather than the .xcodeproj.) Shimmer uses the -[CALayer mask] property to enable shimmering, similar to what's described in John Harper's 2009 WWDC talk (unfortunately no longer online). Shimmer uses CoreAnimation's timing features to smoothly transition "on-beat" when starting and stopping the shimmer.
