large scale on navigation bars, toolbars, and tab bars. When there is enough space like regular height, Apple use. You can try setting the same symbols to navigation bars, toolbars, or tab bars and see how scale work in action. The concept of scale applies to all Apple UI. In the above example, Apple uses scale to adjust the size of symbols to matched available space on the container. Examples of how Apple uses scale to adjust the size of symbols to matched available space
Apple uses this in many places in their UI. You use the scale to make SF symbols work better with surrounding components, but also keep it in sync with the text. Scale is a way for you to adjust your symbols to be a bit larger or smaller, but keep the stroke, baseline, and weight the same as your font. SymbolScale ) ScaleĪs mentioned before, each symbol is also available in three scales: small, medium, and large. Init (pointSize : CGFloat, weight : UIImage. You can pick the one that suit your case. The following are all available options you have. You can also configure SF Symbols with other metrics like point size, weight, scale, and text style. Top: Bold system font of size 24, Bottom: Ultralight system font of size 60Īs you can see, the circular stroke and baseline have matched the weight of the font. The following example shows how SF Symbols adapt to the font it configured with. Let image = UIImage (systemName : "book.circle", withConfiguration : configuration ) I think the most straight forward and precise approach is to configure SF Symbols with a font. We can tell SF Symbols the context of the adjacent text that we want to use with the symbol by passing in a new class, SymbolConfiguration, to UIImage. We would want some way to match this symbol with a font we use. Since SF Symbols are mean to work with a text, the above example might not utilize the full potential of it. SwiftUI: Image (systemName : "book.circle" ) Swift: UIImage (systemName : "book.circle" ) We can initialize it with a new UIImage initializer. We will talk about this in the Scale section SF Symbols are available in a wide range of weights and scales How to use SF Symbols?Īpple treats SF Symbols as an image. It comes in nine weights - from ultralight to black - to match a weight of the San Francisco system font.Įach symbol is also available in three scales: small, medium, and large. It designs to work along with their text. SF Symbols was introduced in WWDC 2019 to work as icon sets (or symbols as Apple called it) to work along with their SF family. Apple keeps developing more and more typeface afterward, e.g., SF Compact Rounded, SF Pro Rounded, SF Mono, and New York. San Francisco (SF) is the name of the Apple typeface that was first released for the watchOS (SF Compact) and later to macOS, iOS, and iPadOS (SF Pro). You can also use foregroundColor to change the color and font to change the thickness, just like an SVG image.Sponsor and reach thousands of iOS developers. It can be treated just like a normal image and, of course, it complies with the View protocol. FaceID icon is displayed in the TabView with Image(systemName: "faceid"). I use 1.square.fill, 2.square.fill and 3.square.fill as TabView icons. In this case, I used TabView to change the SF Symbols in various ways. Only you have to do is Image(systemName: "") to specify the icon. No prior installation is required to use SF Symbols. You can use it as a mock, or you can spend your time to create logic, not looking for materials. It's made of vectors, so you can freely enlarge it, change its thickness and color.
More than 1,500 SF Symbols are available for use in place of icons and images. There is no need to prepare in advance, and you can display them with Image(systemName: ""). You can use SF Symbols as icons in the SwiftUI.
