Parse error during analysis of compilation unit breaks in standard Apple UIKit header

I am evaluating SonarQube for our iOS project, but getting many errors from parsing our header files, and the it stumbles on default UIKit and other headers. Should I ignore this as well? I googled but did not find anything that would reference this issue.

I am also getting a lot of these:

WARN: Unknown language standard "gnu11", will use "Objective-C" from "null" for file /PSPDFKit/iOS/PSPDFKit/Encryption/PSPDFCryptoInputStream.m

Is gnu11 not a supported compile style?

Hi,

To be clear, are you using the build wrapper?
