UnrealBuildTool ignores some xcode settings

I’ve tried export my project to Xcode, add some flags and change some options which I can’t add from ue4 editor.
I’m talking about Runpath Search Paths, Library Search Path and Always Embed Swift Standard Libraries. But it seems that this way doesn’t work.

I receive the following error message:

  "type metadata accessor for (extension in Foundation):Swift.String.Encoding", referenced from:
      (extension in APDTwitterMoPubAdapter):Foundation.Data.(extractVAST in _EF4455D2E5BED47807C45A044A061219)() throws -> Foundation.Data in Appodeal(MoPubRewardedAd.o)
ld: symbol(s) not found for architecture arm64 

And it comes from Engine/Binaries/DotNET/UnrealBuildTool.exe. Is it possible that this tool ignores settings from exported project?
