Error remote build iOS xcode 10.1

Guys I’m having seriuos Trouble Right now.
I am remote-Building my iOS build using UE 4.18.3 and xcode 10.1 using iOS 12.1 SDK.
I get this error:

UATHelper: Packaging (iOS):   /Users/aleksandar/UE4/Builds/LAPTOP-BB7FO20G/C/Program Files/Epic Games/UE_4.18/Engine/Source/Runtime/CoreUObject/Public/UObject/UnrealType.h:3285:37: error: lambda capture 'LocalMapLayoutForCapture' is not used [-Werror,-Wunused-lambda-capture]
UATHelper: Packaging (iOS):   
UATHelper: Packaging (iOS):                           [LocalKeyPropForCapture, KeyPtr, LocalMapLayoutForCapture](void* NewElementKey)
UATHelper: Packaging (iOS):   

I need to update my iOS app (already public) BUT apple now REJECTS build with UE4.18.3 and the older iOS 11 SDK which worked until now!!!

Does anyone know how to get rid of this error because I NEED to build it with iOS SDK 12.1 - apple already rejected the version build with the older SDK.
I tried opening the project with UE4.20.1 but I cannot successfully do the transfer.

Please any help. This is too frustrating

for anyone having the same issues:

@iktomi Thanks the clang setting for the lambda is working. We need to add this in IOSPlatformCompilerPreSetup.h as well as MacPlatformCompilerPreSetup.h (look for those in engine Folder,open These and edit them in visual Studio) Just add this at the end of those files:

// Apple LLVM 9.1.0 (Xcode 9.3)
#if (clang_major > 9) || (clang_major == 9 && clang_minor >= 1)
#pragma clang diagnostic ignored “-Wunused-lambda-capture”
#endif
