How to detect SwiftUI usage programmatically in an iOS application

Question

I am working on a library for iOS, and i need to know if the application using the library is running SwiftUI or not so that i can handle things appropriately.

Is there a way to find this out programmatically in Objective-C?

Answer 1

In the end i did this.

1. Get the root or key window of the application.

2. Check if it's class name contains "UIHostingController"

3. Also nil check for this: NSClassFromString(@"SwiftUI._UIGraphicsView")

You could also check for other swift ui classes but this has covered all cases so far.
