XCTestCase - Undefined symbol
Hello, I began writing tests for a SwiftUI project I've been working on, but was getting some "Undefined symbol" error when attempting to run the tests. I thought maybe it was something with the project/target configuration, so I created a brand new SwiftUI sample app, added in the most basic ViewModel, and was able to reproduce the error. You can find the relevant code snippets below. Any idea how to solve this? ContentViewModel: swift import Foundation class ContentViewModel: ObservableObject {     @Published var description: String     init(description: String) {         self.description = description     } } ContentView: swift import SwiftUI struct ContentView: View {     @StateObject var viewModel: ContentViewModel          var body: some View {         Text(viewModel.description)             .padding()     } } ContentViewModelTests: swift import XCTest @testable import Sample class ContentViewModelTests: XCTestCase {     func testDescription() throws {         let viewModel = ContentViewModel(string: "Hello, world!")         XCTAssertEqual(viewModel.string, "Hello, world!")     } } Error: Undefined symbols for architecture arm64:   "type metadata accessor for Sample.ContentViewModel", referenced from:       Tests_iOS.ContentViewModelTests.testDescription() throws - () in ContentViewModelTests.o   "Sample.ContentViewModel.__allocating_init(string: Swift.String) - Sample.ContentViewModel", referenced from:       Tests_iOS.ContentViewModelTests.testDescription() throws - () in ContentViewModelTests.o ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)
