ParticleEffects.swiftpm

ParticleEffects allows developers to create particle systems with minimal effort that are compatible with macOS, iOS, iPadOS, visionOS, tvOS, and watchOS.

The primary goals are to be easily maintainable by multiple individuals, employ a consistent API that can be used across all platforms, and to be maintainable using Swift Playgrounds on iPad and macOS. APIs are typically present even on platforms that don't support all features so that availability checks do not have to be performed in external code, and where irrelevant, code can simply return optionals.

This is actively maintained so if there is a feature request or change, we will strive to address within a week.

Features

• Can develop and modify without Xcode using Swift Playgrounds on iPad!
• SF Symbol particles
• Image particles
• Emoji particles
• Text particles
• Easily specify multiple symbols/images/emoji/text to use by comma-separating a string.
• Emmitter customizations

Requirements

Most of these minimums are dictated by our usage of Date.now which is needed.

• iOS 15+ (15.2+ minimum required for Swift Playgrounds support)
• macOS 12+
• macCatalyst 13.0+ (first version available)
• tvOS 15.0+
• watchOS 8.0+
• visionOS 1.0+
• Theoretically should work with Linux, Windows, and Vapor, but haven't tested. If you would like to help, please let us know.

Known Issues

See CHANGELOG.md for known issues and roadmap

Installation

Install by adding this as a package dependency to your code. This can be done in Xcode or Swift Playgrounds!

Swift Package Manager

Swift 5+

You can try these examples in a Swift Playground by adding package: https://github.com/kudit/ParticleEffects

If the repository is private, use the following link to import: https://<your-PAT-string>@github.com/kudit/ParticleEffects.git

Or you can manually enter the following in the Package.swift file:

dependencies: [
    .package(url: "https://github.com/kudit/ParticleEffects.git", from: "1.0.0"),
]

Usage

First make sure to import the framework:

import ParticleEffects

Here are some usage examples.

Get the version of ParticleEffects that is imported.

let version = ParticleEffects.version

Create a simple fire emitter.

ParticleSystemView(behavior: .fire)
    .font(.largeTitle)
    .aspectRatio(contentMode: .fit)

Create a rainbow sunburst emitter. Note the ability to take a base behavior and modify specific values.

ParticleSystemView(behavior:
    .sun.modified(
        string: "star.fill",
        birthRate: .frequent,
        blur: Blur.none,
        coloring: .rainbow
    )
).aspectRatio(contentMode: .fit)

Create an emoji confetti emitter.

ParticleSystemView(behavior: .fountain, string: "😊,👍,☺️,👏,🙌")

All these tests can be demonstrated using previews or by running the app executable that is bundled in the Development folder of the module.
