SwiftCollections-Unity

Unity Package Manager host for SwiftCollections.

This repository ships two base Unity packages and two optional FixedMathSharp companion packages. Choose one base package, then add the matching FixedMathSharp companion only if your project uses fixed-point query volumes.

• Current package version: 5.0.0
• Supported Unity version: 2022.3+

Packages

Package	Use it when	Install
com.mrdav30.swiftcollections	You want the standard SwiftCollections package for Unity, including Bounds.ToBoundVolume() and MemoryPack-enabled assemblies.	https://github.com/mrdav30/SwiftCollections-Unity.git?path=/com.mrdav30.swiftcollections
com.mrdav30.swiftcollections.lean	You want the same Unity integration without MemoryPack. Prefer this for Burst AOT or your own serialization stack.	https://github.com/mrdav30/SwiftCollections-Unity.git?path=/com.mrdav30.swiftcollections.lean
com.mrdav30.swiftcollections.fixedmathsharp	You already use com.mrdav30.swiftcollections and need FixedMathSharp query helpers such as FixedBoundVolume and Bounds.ToFixedBoundVolume().	https://github.com/mrdav30/SwiftCollections-Unity.git?path=/com.mrdav30.swiftcollections.fixedmathsharp
com.mrdav30.swiftcollections.fixedmathsharp.lean	You already use com.mrdav30.swiftcollections.lean and need the matching no-MemoryPack FixedMathSharp companion.	https://github.com/mrdav30/SwiftCollections-Unity.git?path=/com.mrdav30.swiftcollections.fixedmathsharp.lean

Package Pairing

Base packages:

• Install either com.mrdav30.swiftcollections or com.mrdav30.swiftcollections.lean.
• Do not install both base packages in the same Unity project.

FixedMathSharp companions:

• Install com.mrdav30.swiftcollections.fixedmathsharp with com.mrdav30.swiftcollections.
• Install com.mrdav30.swiftcollections.fixedmathsharp.lean with com.mrdav30.swiftcollections.lean.
• The companions add fixed-point bounds interop; they do not replace the base packages.

FixedMathSharp Dependency

The *.fixedmathsharp* packages include an editor-side dependency installer that attempts to add the matching FixedMathSharp-Unity Git dependency. They still require the matching SwiftCollections base package listed above.

If Unity does not resolve the FixedMathSharp dependency cleanly, add the matching dependency URL manually or run the package repair menu item under Tools > mrdav30.

• Standard dependency: https://github.com/mrdav30/FixedMathSharp-Unity.git?path=/com.mrdav30.fixedmathsharp
• Lean dependency: https://github.com/mrdav30/FixedMathSharp-Unity.git?path=/com.mrdav30.fixedmathsharp.lean

Tests

The build-and-test workflow runs Unity EditMode tests on Unity 6000.3.9f1 for all four package variants:

• SwiftCollections
• SwiftCollections Lean
• SwiftCollections FixedMathSharp
• SwiftCollections FixedMathSharp Lean

The base package tests live in Tests/EditMode and cover Unity Bounds conversion, a representative BVH query, core DLL loading, and SwiftGameObjectPool reuse and exhaustion behavior. FixedMathSharp companion tests live in Tests/EditMode.FixedMathSharp and cover Bounds.ToFixedBoundVolume().

Notes

• Most core collection behavior lives in the upstream SwiftCollections library and is shipped here as precompiled plugin DLLs.
• Shared Unity-side runtime files are maintained under Build/Base and Build/FixedMathSharp, then synchronized into the package folders.
• Each package folder keeps a short, package-specific install README.
