found (extension .WrapperView instead of (extension in .WrapperView) for UIViewRepresentable

after switching to the version 0.9.3 from 0.9.2 I get this error

import XCTest
import ViewInspector
import AVFoundation
import SwiftUI
@testable import BusinessPhotoApp

class CameraControllerTests: XCTestCase {
	func testViewLoad_shouldNotCrash() throws {
		let (sut, _) = makeSUT()
		XCTAssertNotNil(sut)
	}

	func testViewLoad_renderAVCaptureVideoPreviewLayer() throws {
		var (sut, viewModel) = makeSUT()

		let exp = sut.on(\.didAppear) { view in
			let uiView = try view.view(CameraDeviceController.self).actualView().uiView()

			XCTAssertEqual(uiView.layer.sublayers?.first, viewModel.preview)
		}

		ViewHosting.host(view: sut)
		wait(for: [exp], timeout: 0.1)
	}

	// MARK: - helper

	func makeSUT() -> (sut: CameraDeviceController.WrapperView, viewModel: CameraDeviceViewModel) {
		let cameraDeviceService = CameraDeviceService(
			cameraAccessDelegate: CameraAccessNavigationAdapter()
		)
		let cameraDeviceViewModel = CameraDeviceViewModel(preview: CALayer(layer: Text("hallo")))
		let cameraDeviceStore = CameraDeviceStore(cameraDeviceViewModel: cameraDeviceViewModel)
		let sut = CameraDeviceController.WrapperView(
			cameraDeviceService: cameraDeviceService,
			cameraDeviceViewModel: cameraDeviceViewModel,
			cameraDeviceStore: cameraDeviceStore
		)

		return (sut: sut, viewModel: cameraDeviceViewModel)
	}
}

extension CameraDeviceController {
	struct WrapperView: View {
		var didAppear: ((Self) -> Void)?
		let cameraDeviceService: CameraDeviceService
		let cameraDeviceViewModel: CameraDeviceViewModel
		let cameraDeviceStore: CameraDeviceStore

		var body: some View {
			CameraDeviceController(cameraDeviceStore: cameraDeviceStore)
				.onAppear {
					DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) {
						didAppear?(self)
					}
				}
		}
	}
}

Here my CameraDeviceController which use UIViewRepresentable

import SwiftUI
import AVFoundation

struct CameraDeviceController: UIViewRepresentable {
	@ObservedObject var cameraDeviceStore: CameraDeviceStore

	func makeUIView(context: Context) -> UIView {
		let view = UIView(frame: UIScreen.main.bounds)

		view.layer.addSublayer(cameraDeviceStore.cameraDeviceViewModel.preview)

		return view
	}

	func updateUIView(_ uiView: UIView, context: Context) {}
}

I had to refactor your code to remove references to Service, ViewModel, and Store objects for which you didn't provide the source. Those objects didn't seem essential for the reproduction of the failure, however, the resulting test succeeds for me, I don't get any error:

class CameraControllerTests: XCTestCase {

    func testViewLoad_renderAVCaptureVideoPreviewLayer() throws {
        var sut = CameraDeviceController.WrapperView()
        let exp = sut.on(\.didAppear) { view in
            let uiView = try view.view(CameraDeviceController.self).actualView().uiView()
            XCTAssertEqual(uiView.tag, 422)
        }
        ViewHosting.host(view: sut)
        wait(for: [exp], timeout: 0.1)
    }
}

struct CameraDeviceController: UIViewRepresentable {

    func makeUIView(context: Context) -> UIView {
        let view = UIView(frame: UIScreen.main.bounds)
        view.tag = 422
        return view
    }

    func updateUIView(_ uiView: UIView, context: Context) {}
}

@available(iOS 13.0, macOS 10.15, tvOS 13.0, *)
extension CameraDeviceController {
    struct WrapperView: View {
        var didAppear: ((Self) -> Void)?

        var body: some View {
            CameraDeviceController()
                .onAppear {
                    DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) {
                        didAppear?(self)
                    }
                }
        }
    }
}

Could you run this test and see if the error pops up or not? The error message you posted originally here:

found (extension in BusinessPhotoAppTests):BusinessPhotoApp.CameraDeviceController.WrapperView instead of (extension in BusinessPhotoAppTests):BusinessPhotoApp.CameraDeviceController.WrapperView

I haven't seen this pattern of type prefixes before ((extension in <app>):), could you share details of your environment, that is, Xcode version, Swift version, or any other note about your setup if it's untraditional in any way

@nalexn

Thank you for the fast response. Your code works by me. I added @available but nothing change.

Here my setup:

Xcode Version 14.2 (14C18)
Swift 5
Dev Target 16.1

In the worst case, I will give you access to the project. but before I muss bring all over tests to green ;-)
