In plain English

GlowEffectKit is a Swift package for iOS and macOS app developers who want to add an animated glowing border effect to buttons, cards, or any other SwiftUI view. The glow animates continuously, pulsing in intensity, and is powered by a Metal shader included in the package so there are no external dependencies to manage. Using it is a single line of code. You add .glowEffect(isActive: true) to any SwiftUI view and the animation starts. When isActive is set to false, the glow stops. This on/off control makes it straightforward to tie the effect to a state change, such as showing a loading animation on a button while a network request is in progress, or highlighting a selected card. For developers who want more control, there is a configuration object where you can adjust the peak scale of the pulse, the animation duration, the opacity of the glow, the shader amplitude, and the frame rate of the animation. The defaults work without any configuration. The package requires iOS 18 or macOS 15 and Swift 6. Installation goes through Swift Package Manager in Xcode: add the GitHub repository URL and the package appears as a dependency. The README includes a working code example showing the effect applied to buttons and a custom card view. The license is MIT, so the package can be used freely in any project, including commercial apps.

Copy-paste prompts

Prompt 1
I'm using GlowEffectKit. Add a glowing border to my SwiftUI card view that turns on when the card is selected and off when it's not.
Prompt 2
Show me how to use GlowEffectConfiguration to create a slow, subtle glow at low opacity for a background element in my iOS app.
Prompt 3
I want to apply a glowEffect to a custom SwiftUI shape that is not a rectangle. Is that possible with GlowEffectKit, and if so how?
