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.

This is what the code looks like, and the ImagePicker class conforms to the UIViewControllerRepresentable protocol.Sponsor and reach thousands of iOS developers. Next, let's add a placeholder for the image we will feed into the ML model:Ĭreate a new file: ImagePicker.swift and import both SwiftUI and UIKit
In ContentView.swift, let's add two system images to bring up a sheet with the image controller interface when we click on any of them. We will extend our app prediction categories to a few thousand everyday items such as different fruits and significantly broaden SeeFood's use cases. If you have not watched Silicon Valley, here is a quick snippet of what Jing Yang's app is about.Īs you can see, Jing Yang's app has a fundamental flaw in that it can only tell if an object is a hot dog or not, so Pizza will be classified as a non-hot dog thing. The original idea came from this episode from Silicon Valley. The complete code repo can be downloaded on GitHub: So we can shoot a new photo or pick up an existing image from our photo albums, or take a picture using our built-in cameras on iOS. In this article, I will show you how to use SwiftUI to wrap up the UIImagePickerController from the UIKit framework and create an app that tells if it is a hotdog or not. One of the most significant issues for AI and machine learning practitioners like myself is that there are no native SwiftUI-based views for Camera related applications/use cases. However, it is still in its relatively early stage. The SwiftUI framework has been released for about 2 years and has gained tremendous momentum in the iOS developer community. WWDC 2021 is only a week away from today (May 31, 2021).
