NS_SWIFT_NAME is an attribute in Objective-C that is used to specify a Swift-compatible name for an Objective-C symbol. When writing Objective-C code that needs to be accessed from Swift, it is often necessary to provide alternate names for Objective-C symbols that have names that do not conform to Swift’s naming conventions. For example, in Objective-C,
I came across this question on stackoverflow. https://stackoverflow.com/questions/32346456/accessing-non-static-constant-in-static-function-of-swift-class Basically it asked, how we can access instance members from static functions. The answer would be no, we can’t access instance variables from static method. But this is possible using a singleton design pattern. The actual code is shown below This is how I can alter it.
Normally when implementing buttons in iOS, which needs rounded corners, we use the corner radius API to round the corners. In order to do this, you would need to calculate the height and then divide by a number you deem suitable. This is not always a suitable choice, since you would always need to fetch
You will commonly need to iterate through similar views and display them in SwiftUI. For e.g. similar to the image shown below. Normally we would use ForEach to iterate and display them. ForEach is a structure that computes views on demand from an underlying collection of identified data. In order to make it work, you
It’s pretty easy to accomplish this animation using the ObservableObject. Let me show you how. Use the below class to display all your views one by one. Display your views DaySwiftUIView using a for loop. Let’s write the actual class which does this animation. The single line of code which animates the view is .animation(Animation
The below diagram shows the pattern I have been following to make my integration easy between the various parts of my code. Dependencies: iOS 13 is the deployment target Let’s start with an Xcode Objective-C project. Let’s name the project Interoperability. Please pay careful attention to your project name. You would be using the name
