Sad times,
Everything an SF Symbol App Should Have
The only reason I rate this 4 instead of 5 stars is it lacks two features. One of which I see as easy to implement as you already have ‘.renderingMode(.original)’ in the code snippet for the multicolor symbols, why not offer a drop down; or include in the modifier tab, a way to switch between others such as monochromatic?
The other feature is my main gripe though as it forces me to lookup every symbol I haven’t used; or don’t use enough to know for sure, in another app. This feature is a little info icon on some of the symbols that provide helpful information.. info such as the ‘pencil.tip.crop.circle.badge.plus’ symbol is actually the Apple Markup symbol, which should come with a hefty warning of "This symbol may not be modified and may only be used to refer to Apple's Markup feature."
Therefore, any symbol I don’t use often has to be looked up elsewhere after using this app. Otherwise I may not realize that’s the icon for Markup and use it for a simple edit name icon in my app.
