WebDriverAgent build failed

[cindysongzi]

Info
System: Mac OS Sierra v10.12.6
Xcode: 9.2
Real Device: iPad mini v11.2

I downloaded facebookarchive/WebDriverAgent from github, run ./Scripts/bootstrap.sh to download packages successfully.
Open WebDriverAgent in XCode, rename bundleID, input developerID, select real device by clicking Product->Destination, select Product -> Scheme -> WebDriverAgentRunner, and then build failed.

The following is the error message:

error: unknown warning option '-Wno-objc-messaging-id'; did you mean '-Wno-objc-cocoa-api'? [-Werror,-Wunknown-warning-option]
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1

Can anybody help? Thanks.

在 WebDriverAgentRunner 和 WebDriverAgentLib 这两个 Build Settings -> Other Warning Flags 分别增加 -Wno-unknown-warning-option , 应该就好了
