Again, I recommend you check out the WWDC session on SF symbols here. UIKit let image UIImage(systemName: doc) let imageView UIImageView(image: image) imageView.tintColor. Well, that’s the basics – there’s a lot more to look at – such as alignment, automatic configuration based on size class, making your app with SF symbols compatible with devices with < iOS 13, and building your own SF symbols. Of course, as we saw at the start of this post, you can also include SF symbols in SwiftUI views. SAVE 50 To celebrate WWDC23, all our books and bundles are half price, so you can take your Swift knowledge further without spending bigGet the Swift Power Pack to build your iOS career faster, get the Swift Platform Pack to builds apps for macOS, watchOS, and beyond, or get the Swift Plus Pack to learn advanced design patterns, testing skills, and more. We also saw at the start of this post that you can also include SF symbols in SwiftUI views.You might be interested to know you can also add them in the storyboard: This is possible with SF symbols too - instead of specifying the point size, you can create the config property using a text style, just as you might with a label or text field:īy the way, so far we’ve been looking at how to add SF symbols in code. Having point size available is great, but we generally try to avoid specifying a point size with text - instead we prefer to use text styles, such as Body, Headline, etc where possible to take advantage of dynamic type. Perhaps you might be lining up an image with a label, adding an image to a button, or even inserting an SF symbol in a string! It should be mentioned that inserting an SF symbol into a string isn’t working yet for the current beta of Xcode 11, but it sounds very promising, adjusting the style of the symbol to the text surrounding it! Well, the scale property allows you to adjust the scale of a symbol in relation to the text around it without having to adjust the pointSize. Why have both pointSize and scale, you might ask. It should be noted that pointSize refers to a typographical point size – the same point size a font uses – rather than points on the screen. You can adjust the weight and scale of the image, along with its pointSize, using a config property: You’ll find an example of these in the Human Interface Guidelines: In the SF Symbols program you’ll notice you can play with the weight and scale of the image. You’ll also find guidance there for building your own SF Symbol, using the SF Symbols program. You’ll also find Apple’s guidelines for using SF Symbols in the Human Interface Guidelines here. SwiftUI: let heartImage = Image(systemName: "heart.There is a WWDC session on SF symbols well worth checking out here. UIKit: let heartImage = UIImage(systemName: "heart.fill") These new symbols are available in apps running iOS 16, iPadOS 16, macOS 13, tvOS 16, and watchOS 9. SF Symbols 4 features over 1000 new symbols, variable color, automatic rendering, and new unified layer annotation. SF Symbols 3 features over 600 new symbols, enhanced color customization, a new inspector, and improved support for custom symbols. Localized symbol variants for right-to-left writing systems, as wellĪs script-specific symbols for Arabic, Devanagari, and Hebrew.Greater control over horizontal alignment
