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 take long until first ideas came up to make these icons accessible in a safe way using a framework. And this is just what SFSafeSymbols does!
SFSafeSymbols can be installed via Swift Package Manager, Accio, Carthage or CocoaPods.
Supported platforms are iOS (11.0+), tvOS (11.0+) and watchOS (6.0+), although the actual functionality is of course only accessible starting with iOS 13.0, tvOS 13.0 and watchOS 6.0.
To integrate using Apple's Swift package manager, add the following as a dependency to your Package.swift:
.package(url: "https://github.com/piknotech/SFSafeSymbols.git", .upToNextMajor(from: "1.1.1"))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 SwiftPM, then run accio update instead of swift package update.
Add the following entry to your Cartfile:
github "piknotech/SFSafeSymbols" ~> 1.1.1
Then run carthage update.
Add the following entry to your Podfile:
pod 'SFSafeSymbols', '~> 1.1.1'Then run pod install.
All the system icons are accessible via the SFSymbol enum. They are named similar to Apple's names, but use a lower camel case style and prefix names with leading numbers with a _ character:
c.circle ~> SFSymbol.cCircle
e.circle.fill ~> SFSymbol.eCircleFill
11.circle.fill ~> SFSymbol._11CircleFill
A SF Symbol UIImage can now be initialized using the SFSymbol enum. This image is already unwrapped, so you get a UIImage instead of a UIImage?:
UIImage(systemSymbol: .cCircle)
UIImage(systemSymbol: SFSymbol.eCircleFill)
UIImage(systemSymbol: ._11CircleFill, withConfiguration: /* Some UIImage.Configuration */)A SF Symbol SwiftUI.Image can also be initialized using the SFSymbol enum. It's also unwrapped, so you get a SwiftUI.Image instead of a SwiftUI.Image?:
Image(systemSymbol: .cCircle)
Image(systemSymbol: SFSymbol.eCircleFill)There's also an initializer for UIApplicationShortcutItem:
UIApplicationShortcutIcon(systemSymbol: .cCircle)
UIApplicationShortcutIcon(systemSymbol: SFSymbol.eCircleFill)All symbols are tested via a CI (on the latest iOS & tvOS versions), so you can be sure your code won't crash because an image couldn't be found!
