Additional Linker Flags on iOS - confusing behavior

Hi,

I don’t know if it’s a bug or missing feature but when I add something to “Additional Linker Flags” in iOS project settings it is inserted to GetCompileArguments_Global() function (line 206) but should be inserted to GetLinkArguments_Global() function (line 357) in IOSToolChain.cs file.
Currently it’s useless or property name is confusing because it should be added to “Other Linker Flags” like in Xcode. I need to add flag “-ObjC” which is required by the most libraries for iOS.

Example: | Ads SDK Documentation

Anyone can explain this? Thank you for your reply.

It’s exactly this problem: https://github.com/EpicGames/UnrealEngine/pull/1775 Please fix this as soon as possible.

You don’t need to use ‘-ObjC’ for other linker flags since 4.11. At UnrealEngine/Engine/Source/Programs/UnrealBuildTool/IOS/IOSToolChain.cs line 488, you can see ‘Result += " -ObjC";’. Don’t waste you time like me :frowning:
