probably the rareness of the version conflicts is a function of this rash having gone down.. but the idea that a build tool would just load up one or the other of something and clear your artifact for takeoff is laughably stupid, no? at the very least a warning or whatever.. if there were strategies, you could even show what was done.. these days the level of lint and warnings is maybe going too far in the other direction, but personally I like that, xcode gives you warnings about autolayout that are extreme, and the risk there is a box rendered a pixels differently than you are seeing, the build risk is a crash.
