[Unity] Unity iOS Resolver(EDM4U)에서 xcworkspace 생성되지 않는 이슈

Unity iOS Resolver는 Unity에서 사용할 수 있는 iOS 의존성 관리 툴입니다.

보통은 Unity 빌드를 하면 알아서 pods 설치 및 xcworkspace가 생성되어야 하는데, wcworkspace가 생성되지 않는 이슈를 발견하여 정리합니다.

#1 현상

Cocoapods 1.11.2를 사용하던 중, Unity iOS Resolver 설정 후 Unity 빌드 시 wcworkspace가 생성되지 않았습니다.

아래는 에러 로그입니다.

iOS framework addition failed due to a CocoaPods installation failure. This will will likely result in an non-functional Xcode project.

After the failure, "pod repo update" was executed and succeeded. "pod install" was then attempted again, and still failed. This may be due to a broken CocoaPods installation. See: https://guides.cocoapods.org/using/troubleshooting.html for potential solutions.

pod install output:

에러 로그를 보면 뭔가 pods 설치하다가 실패를 했다고 합니다. 이것저것 조사하다가 3가지 해결방법을 찾았습니다.

#2 해결방법

1) 그냥 pod install 직접 호출

Unity 빌드를 하면 xcworkspace만 만들어지지 않을 뿐, xcodeproj는 생성됩니다.
Podfile이 문제가 없다면, 터미널로 가서 pod install을 직접 호출해줍니다.
(다만 이 방법은, Unity 빌드할 때마다 매번 pod install을 호출해줘야 합니다ㅠㅠ)

2) Use Shell to Execute Cocoapod Tool 체크박스 해제

Assets > External > Dependency Manager > iOS Resolver > Settings로 가서 Use Shell to Execute Cocoapod Tool 체크박스를 해제해주세요.

 

(이 설정은 Cocoapods 명령어 실행 전에 shell 환경설정이 필요한 경우 사용하는 것으로 굳이 사용할 필요가 없다면 해제해도 무방할 것 같습니다.)

3) Cocoapods 1.10.x 버전으로 다운그레이드

Cocoapods 1.10.x 버전으로 다운그레이드 후에 다시 Unity 빌드를 하면 정상적으로 xcworkspace가 설치됩니다.
(현재 발생하는 이슈는 Cocoapdos 1.11.x의 버그라고 합니다....)
