This is no longer true. I added SIMD to SwiftGL. Here's one million mat4x4
multiplications:
SIMD module direct : 1.489s
SwiftGL + SIMD : 1.487s
SwiftGL plai

There are three pieces of the simd module on OS X / iOS.
- There’s the SDK overlay, which is part of Swift.
- There are C/C++ headers /usr/include/simd/*.h, which comprise the bulk of the
C implementation.
- A small number of routines require external calls, whose implementations are
part of lib

The functions in GLSL like normalize(), cross(), dot(), distance(). The
idea is that you shouldn't have to remember two APIs to be productive. Like
what glm does for C++.

Yeah, but...

SwiftGLmath works today for everyone. It's not as fast as packed SIMD but
it's still real
Any plans to make simd open-source? or available for Linux?

Hey David —
FYI essentially all of this stuff is already present in the simd module
(stdlib/public/SDK/simd/simd.swift.gyb or ‘import simd'), albeit without nice
generics, and with some different stylistic choices because simd is at present
a straight Swift port of a subset of the simd C/Obj-C/

I've been working on a math library for SwiftGL. It's looking good.
Vector2, Vector3, Vector4, Matrix2x2, Matrix3x3, Matrix4x4 are implemented
with all arithmetic. You can even swizzle just like GLSL.
var myVec = vec4(1, 2, 3, 4)
myVec.ab = vec2(99, 98)
print(myVec) //=> (1, 2, 98, 99)
There's
