SwiftUI Preview - Undefined symbols for architecture arm64
Starting on Xcode 15.3 and 15.4 my SwiftUI Previews stopped working with the following error: == PREVIEW UPDATE ERROR:     LinkDylibError: Failed to build ContentView.swift          Linking failed: linker command failed with exit code 1 (use -v to see invocation)          ld: warning: search path '/Applications/Xcode.app/Contents/SharedFrameworks-iphonesimulator' not found     Undefined symbols for architecture arm64:       "static MyLibrary.DisplayUtil.getText() -> Swift.String", referenced from:           closure #1 () -> SwiftUI.Text in (extension in Demo_Broken_Preview_PreviewReplacement_ContentView_1):Demo_Broken_Preview.ContentView.(__preview__body in _1BA320C8FB5388C953E1E463345C3D72).getter : some in ContentView.1.preview-thunk.o       "type metadata accessor for MyLibrary.DisplayUtil", referenced from:           closure #1 () -> SwiftUI.Text in (extension in Demo_Broken_Preview_PreviewReplacement_ContentView_1):Demo_Broken_Preview.ContentView.(__preview__body in _1BA320C8FB5388C953E1E463345C3D72).getter : some in ContentView.1.preview-thunk.o     ld: symbol(s) not found for architecture arm64     clang: error: linker command failed with exit code 1 (use -v to see invocation) After much trial and error, I narrowed it down to my SwiftUI views using properties or functions inside components in Swift Packages. This is a simple example of my Swift Package: public class DisplayUtil {     public func getText() -> String {         return "Text"     }          public static func getText() -> String {         return "Text"     } } And my SwiftUI View import SwiftUI import MyLibrary struct ContentView: View {     var body: some View {         VStack {             Text(DisplayUtil.getText())         }         .padding()     } } #Preview {     ContentView() } The same code works fine on Xcode 15.2 Link to the sample project: https://www.icloud.com/iclouddrive/0c00AD0esi2PwqqiRggokfwGw#Demo%5FBroken%5FPreview Is anybody else having a similar issue?
