Always Embed Swift Standard Libraries 설정도 확인하고

Other Linker Flags에 -ObjC 추가 해보고 Swift 라이브러리들도 수동으로 추가해 보았으나 여전히 빌드가 안된다. 

 

Xcode 를 업데이트 해야 해결될 거 같기도 해서 ironSource 미디에이션 Changelog 를 보니

8.6.0.0.0

• Certified with IronSource SDK 8.6.0.0.
• Updated minimum Xcode requirement to 16.0 to match IronSource SDK.

정말 Xcode 를 업데이트 해야하네?!

... 빌드를 빨리 올려야 하는 상황이라 우선은 ironSource 어댑터 버전을 낮추고 빌드해서 올렸다. 

 

pod 'AppLovinMediationIronSourceAdapter', '~> 8.5.1.0.0'

 

올리고 보니

 

결론은 Xcode를 업데이트 하긴 해야겠구나
