Does KIF work with SwiftUI?

[rauls4]

Hello, we are looking for UI testing options and KIF has come up. I have not been able to find out about SwiftUI compatibility.

Any information would be appreciated.

Thanks

Can confirm it works, and I've also tried some interesting thing, using SwiftUI previews in tests:

    func testContentViewPreviews() {
        // Given
        let contentViewPreviews = ContentView_Previews.previews
        
        // When
        solo.showViewControllerInCleanWindow(UIHostingController(rootView: contentViewPreviews))
        let shouldFindVersion = solo.waitFor(textWithPrefix: "Version")
        
        // Expect
        XCTAssertTrue(shouldFindVersion)
        attachScreenshot(name: "contentViewPreviews")
        solo.window?.printHierarchy()
    }

Here is the log:

Yes, this works for me. All I had to do is to use UIHostingController(:) in place of ViewController and load the SwiftUI View
