Use var in struct in Swift

TL;DR: Use var for properties in struct as long as it serves as a nominal tuple. In most cases, there is no obvious benefit to using let for struct properties.

Simple Example

Let's start with a simple example:

struct MyStruct {

realvjy

// Lines
float hash( float n ) {
    return fract(sin(n)*753.5453123);
}

// Slight modification of iq's noise function.
float noise(vector_float2 x )
{
    vector_float2 p = floor(x);
    vector_float2 f = fract(x);
