At WWDC 2019, Apple announced a new library of icons that come included with iOS 13. To browse them, there's even a dedicated Mac app called SF Symbols. However, developers still have to copy the name of an icon and reference it unsafely, resulting in code like this:

UIImage(systemName: "circle.fill")

It didn't took long until first ideas came up to make these icons accessible in a safe way using a framework. And this is just what this framework does!


SFSafeSymbols can be installed via Swift Package Manager, Accio, Carthage or CocoaPods:

Swift Package Manager

To integrate using Apple's Swift package manager, add the following as a dependency to your Package.swift:

.package(url: "", .upToNextMajor(from: "0.3"))

After specifying "SFSafeSymbols" as a dependency of the target in which you want to use it, run swift package update.


Do the same configurations as for Swift PM, then run accio update instead of swift package update.


Make the following entry in your Cartfile:

github "piknotech/SFSafeSymbols" ~> 0.3

Then run carthage update.


Add the following entry in your Podfile:

pod 'SFSafeSymbols', '~> 0.3'

Then run pod install.


All the system icons are accessible via the SFSymbol enum. They are named similar to Apple's naming, but use a lower camel case style and prefix names with leading numbers with a _ character:        ==> SFSymbol.cCircle   ==> SFSymbol.eCircleFill  ==> SFSymbol._11CircleFill

You can now either create the corresponding UIImage by initializing it using the SFSymbol...

UIImage(systemSymbol: .cCircle)
UIImage(systemSymbol: .eCircleFill, withConfiguration: /* Some UIImage.Configuration */)
UIImage(systemSymbol: ._11CircleFill, compatibleWith: /* Some UITraitCollection */)

... or by calling a function on your SFSymbol instance:

SFSymbol.eCircleFill.toImage(withConfiguration: /* Some UIImage.Configuration */)
SFSymbol._11CircleFill.toImage(compatibleWith: /* Some UITraitCollection */)

You can also create a SwiftUI.Image by using new initializers that take a SFSymbol reference:

Image(systemSymbol: .cCircle)

All symbols are tested so you can be sure your code won't crash because an image couldn't be found!
