Description Gergely Oroszi 2016-05-02 07:49:26 UTC
It happens if a build is started from Visual Studio 2015 Enterprise, in case of iOS class library, when it is being compiled, the VS is doing nothing visible, just after 5-8 minutes it continues the build with the runnable iOS project, which needs additional minutes to be compiled. A Mac Mini and a PC is used, below you can see the config.

Thank you for the log file. It appears that the issue is around the PackLibraryResources task. We are currently working on a fix for this.
