@delcerrocristian have you tried to add an empty swift file on your project?
When you add an empty swift file, XCode will ask you "Create Bridging Header".

It will include to the Header Search Path on your build settings:

$(TOOLCHAIN_DIR)/usr/lib/swift/$(PLATFORM_NAME)
$(TOOLCHAIN_DIR)/usr/lib/swift-5.0/$(PLATFORM_NAME)

Big thanks!
But be sure you didn't delete an empty file after creating, otherwise it doesn't work 🙂

@delcerrocristian você tentou adicionar um arquivo swift vazio ao seu projeto?
Quando você adiciona um arquivo swift vazio, o XCode irá perguntar a você "Create Bridging Header".

Isso incluirá o Caminho de pesquisa do cabeçalho nas configurações de sua construção:

$(TOOLCHAIN_DIR)/usr/lib/swift/$(PLATFORM_NAME)
$(TOOLCHAIN_DIR)/usr/lib/swift-5.0/$(PLATFORM_NAME)

This works by also reminding you to add a new Swift file inside your APP folder.

@delcerrocristian 프로젝트에 빈 신속한 파일을 추가하려고 했습니까?
빈 swift 파일을 추가하면 XCode에서 "브리징 헤더 생성"을 요청합니다.

빌드 설정의 헤더 검색 경로에 포함됩니다.

$(TOOLCHAIN_DIR)/usr/lib/swift/$(PLATFORM_NAME)
$(TOOLCHAIN_DIR)/usr/lib/swift-5.0/$(PLATFORM_NAME)

Where exactly should I create the file? In my react-native application root? And the try to build the app (with npx react-native run-ios)? Meanwhile building, it will prompt me something?

@kanes115 Open up the .xcworkspace xcode project in your ios/ folder. In xcode file -> new file -> swift. It'll prompt you

Well, that did the trick! Why does that fix this problem, though? I don't really understand how the error relates to the fix.

[felire]

It works for me! Thanks! But Can I delete the swift and the bridging file but maintaining the changes on the project file? Because they are empty files, it's really weird to have them on the project

[anees17861]

Can someone tell me how to fix it on the library side. I'm developing a xcframework library.
I am using Xcode 11.5 to build it while my client has 12.2. Should I update myself to 12.2 as well and build again? If yes, do I need to release a new XCFramework for every Xcode update?
