In SwiftUI, you adjust the scale of an SF Symbol like this: Image(systemName: "house")Īs I said, this happens in combination with any custom font, so you can use both if you want: Image(systemName: "house") However, we can also scale SF Symbols to be slightly smaller or slightly larger, independent on their font size, which allows you even more fine-grained control over how they look in your UI. You’ve just seen how SF Symbols can have custom font sizes attached, allowing them to flow inside your text neatly.

Let image = UIImage(systemName: "airplane", withConfiguration: config) How to adjust the scale of an SF Symbol Or using a custom font size like this: let config = UIImage.SymbolConfiguration(pointSize: 72) Let image = UIImage(systemName: "airplane", withConfiguration: config) In UIKit, adjusting the size of a symbol is done using UIImage.SymbolConfiguration, like this: let config = UIImage.SymbolConfiguration(textStyle. Or using a custom font size like this: Image(systemName: "house")
In SwiftUI, adjusting the size an SF Symbol is done using the font() modifier with a built-in text style, like this: Image(systemName: "airplane") This also works for the built-in Dynamic Type sizes, where SF Symbols will adapt themselves to match other text in your UI. SF Symbols are entirely vector graphics, so you can adjust their size freely without losing quality.

If you want to place it inside the text string, it’s better to use string interpolation with Image, like this: Text("Please press the \(Image(systemName: "calendar")) button")įor UIKit the code is a little more complex because you need to use NSAttributedString and NSTextAttachment to render something into a UILabel, but the same code lets you place the images wherever you want them: let attachment = NSTextAttachment()Īttachment.image = UIImage(systemName: "xmark.circle") In SwiftUI placing an image next to text is done like this: Label("Please try again", systemImage: "xmark.circle") SF Symbols work great when used inside text, particularly when they contain common symbols such as error crosses, check marks, calendars, and similar. Let imageView = UIImageView(image: image) How to place SF Symbols next to text In UIKit you need to use UIImage then place it in a UIImageView, like this: let image = UIImage(systemName: "star") In SwiftUI loading an image is done by placing an Image into your view hierarchy using its systemName initializer: Image(systemName: "star") We’ll be using “star” here, but if you’re using the SF Symbols app you can right-click any symbol and choose Copy Name.
