When specifying home screen quick actions, UIApplicationShortcutItems, in your Info.plist, is there a way to use a system image from SF Symbols?

The docs noting the available iOS keys doesn't specify a key to do this, besides specifying one of the predefined enum cases from UIApplicationShortcutItemIconType such as UIApplicationShortcutIconTypeSearch.

It is possible to use a system image when creating dynamic quick actions via a new initializer UIApplicationShortcutIcon.init(systemImageName: String). Is there a Info.plist key that allows this for static quick actions?

回答1:

Use UIApplicationShortcutItemIconSymbolName instead of UIApplicationShortcutItemIconFile in your Info.plist.

Seems like there is no way to directly use those. But since there are not much symbols that you need to use statically at the same time, here is the solution:

Select the symbol you need and export it from SF Symbols.app:

Import it in the Assets.xcassets:

Use it's name for the key UIApplicationShortcutItemIconFile:

Result

I hope Apple add direct support for SF Symbols soon.

I read the docs and tried several methods to get this working but the conclusion I reached is that this won't be possible for two main reasons:

SF Symbols are only available for native use on devices running iOS 13 or older.
Info.plist file can specify a platform and device type but you can't specify an OS version.

In Apple's documents it's also stated that:

You can use SF Symbols in apps running in iOS 13 and later, watchOS 6 and later, and tvOS 13 and later. To browse the full set of symbols, download the SF Symbols app.

This means that you are able to use these symbols but with a standard way. Here is what you can do:
