I found a problem making a build using Enterprise build in Xcode using Daily Build 2972.
Typically, all the plugins you’re using should by copied to /Applications/CoronaEnterprise/Plugins, then you do a Build.
This is fine for all plugins except the libgamenetwork-apple.a.
You have to manually copy it to the /Applications/CoronaEnterprise/Corona/ios/lib directory for a build to work.
