Animation tool was unable to run successfully on Mac

I can package for mac but I failed to package for iOS. I heard some people had same log on windows. But don’t know how to solve this on mac. Also, my project is a full-blueprint one. Here is a part of log:

MainFrameActions: (iOS): at BuildCookRun.ExecuteBuild () [0x00000] in :0 MainFrameActions: (iOS): at BuildCommand.Execute () [0x00000] in :0 MainFrameActions: (iOS): Program.Main: ERROR: CodeSign Failed MainFrameActions: (iOS): Program.Main: AutomationTool exiting with ExitCode=32 MainFrameActions: (iOS): Domain_ProcessExit MainFrameActions: (iOS): RunUAT ERROR: AutomationTool was unable to run successfully.

Any answer could be a great help. Thanks guys!
