Nextjs and native browser components that I style in ways that are familiar to mobile app users. So like ,<input> and you use CSS to give it 8px border radius and 48px height. Since I'm going for a material style with an iOS feel I mix the forms. Another example is I use a hamburger menu but I use sf symbols light "icon" as an SVG.
My PWA is used on Apple products and I developed it with the intent of being used on Apple Products. I cannot control if a user uses a non Apple product. I cannot be expected to restrict what products my users use to access my product.
Added:
I will also add that the icons I'm using are very basic. Found in many ui kits. The minus symbol, arrows, trash can. The only one that is recognizable to the trained eye is that I'm use the copy symbol (two pages). So if it's going to be an issue for that one I would be fine to use something from Google. I just want Apple to know that I'm on team Apple. I want people to use Apple products. When they come out with SwiftUI Kit for web, I will be the first user. For a product like mine, most users are iphone users.
