What it is

Advance is a physics-based animation library for iOS, tvOS, and macOS written in Swift that uses spring dynamics and decay simulations to create realistic, responsive motion. Instead of traditional keyframe animations, it applies real-world physics principles (spring tension, damping, velocity) to animate UI properties, allowing views to move and respond naturally to user interactions. Single-package structure: Advance.xcodeproj contains the main framework code (not shown in file list but referenced in .podspec and Package.swift), separate build targets for iOS/tvOS/macOS in Advance.xcodeproj/xcshareddata/xcschemes/, and Samples/SampleApp-{iOS|macOS} containing working demo apps.…

Start here

Open these first:

• Sources/Advance.h — Main public header that exports the entire animation framework API; defines the public interface that all consumers depend on
• Sources/Spring.swift — Core Spring animation class implementing physics-based motion; the primary abstraction users interact with for animating…
• Sources/Animator.swift — Central animation loop manager that coordinates all active animations and drives the CADisplayLink update cycle
• Sources/SpringSolver.swift — Physics solver implementing spring mathematics (damping, stiffness, mass); critical for correctness of animation behavior
• Sources/Advanceable.swift — Protocol defining animatable types; establishes the type system that allows springs to work with any conforming value type

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/timdonnelly/Advance.git
cd Advance
open Advance.xcodeproj
# For SPM: add to Package.swift
.package(url: "https://github.com/timdonnelly/Advance", from: "3.0.0")
# Or CocoaPods: pod 'Advance'

Daily commands:

Xcode project: open Advance.xcodeproj, select SampleApp-iOS scheme, build & run (Cmd+R). The sample app demonstrates spring animations, decay animations, and direct manipulation. Unit tests: select `Advance-Unit…

Key cautions & unknowns

• Stale — last commit 4y ago
• Solo or near-solo (1 contributor active in recent commits)
• No obvious environment variables or service dependencies. Key gotchas: (1) Physics parameters (tension, damping, threshold) are tuning-sensitive—small changes yield dramatically different animation feel, so…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.

Evidence note

Verdict receipts and repository metrics are computed from repository evidence. Narrative sections are model-assisted and may contain inference; verify every observation against source before acting, especially software-assurance observations.
