I read the vague guidance in the HIG (https://developer.apple.com/design/human-interface-guidelines/ios/icons-and-images/custom-icons/) on making a "glyph". I've tried Pixelmator, Graphic, and Sketch to make all grayscale on transparent PNGs, SVGs, and PDFs. I still cannot make an asset that is tintable when I use it in a TabView tabItem Image.
If I use an SF Symbols image (systemName) then I get a tintable icon. The technical guidance in the HIG is too vague. What is "monochomatic" here? 1-bit color? Grayscale? "Uses a mask to define its shape" is also vague. Do they mean an alpha channel? An alpha mask?
I don't have Photoshop or Illustrator, so if someone can give me some clear technical guidance relevant to one of the tools I do have that'd be appreciated.
