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. First you need to add the image to a new image set in your Assets. Otherwise, it won't work when we extend this to macOS since UIKit is only available for iOS.Ĭhapter 3: Wrap up UIImageView Controller You can display an image in a SwiftUI view by using the Image view. We will extend our app prediction categories to a few thousand everyday items such as different fruits and significantly broaden SeeFood's use cases. In this tutorial, we will try to find the solution to Swift Get 'System' Asset Image through programming. 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 shortcoming 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 create an app that tells if it is a hotdog or not. In this example we will name are state property isExpanded and set it to false. First we will need to create a State variable so that we can control when we show our menu buttons. Use SF Symbols to find symbols and their corresponding names. Use this method to retrieve system-defined symbol images. let image // your image let targetSize CGSize(width: 100, height: 100) let scaledImage image. To create a custom symbol image from your apps asset catalog, use init(:) instead. Now that we have our menu button created lets go back and add it to our ExpandableButton.swift file. This initializer creates an image using a system-provided symbol. The object containing the specified symbol image, or nil if no suitable image was found. That’s it You now have an extension that will resize any UIImage to a target size without stretching or distorting the original image. 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. This initializer creates an image using a system-provided symbol. Right-click on the NavSplitDemo folder in the Project navigator, select the New File menu option, and create a new Swift file named IconCategory.swift. However, it is still in its relatively early stage. Our first requirement is a class declaration we can use to store category names and corresponding icons. 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).
