Swift function for creating a custom CGColorSpace

I am looking for a Swift developer who can create a custom CGColorSpace for macOS. The main function of this custom CGColorSpace will be to render graphics.

Skills and experience required:
- Proficiency in Swift programming language
- Strong knowledge of macOS development
- Experience with creating custom CGColorSpaces
- Familiarity with rendering graphics

The ideal candidate will be able to create the custom CGColorSpace from scratch, as no preferred color profile has been specified. The developer should have a strong understanding of color correction and image editing techniques.

This project is perfect for someone who enjoys working with graphics and has a passion for creating visually stunning applications on the macOS platform.

The application already exists and is using Core Graphics to create a CGPDFDocument. The only issue left to solve is creating a custom color space and then using that to set the CGContext.setFillColorSpace() or CGContext.setStrokeColorSpace() prior to drawing using CGContext.drawRect() or other. CGContext drawing APIS.

Only specific objects need to be draw with that color space. However there are two potential solutions 1) create a custom icc profile for the color space and load into macOS and then use that profile - presumably accessible via the ColorSyncManager APIs or 2) programmatically construct on the fly using the CGColorSpace(propertyListPlist:CFPropertyList) API. The latter is preferable, however some knowledge of how to create the color space CFPropertyList is required.

I believe it may be necessary to construct the Data object containing the custom color space as per Figure 2 on the linked page

Below is an example of the custom color space

"ColorSpace<Dictionary>" = {
"Cs2<Array>" = (
Separation,
Spot1,
DeviceCMYK,
{
"BitsPerSample<Integer>" = 8;
"Domain<Array>" = (
0,
1
);
"Filter<Name>" = FlateDecode;
"FunctionType<Integer>" = 0;
"Length<Integer>" = 526;
"Range<Array>" = (
0,
1,
0,
1,
0,
1,
0,
1
);
"Size<Array>" = (
1024
);
}
);
};
