Folks,

just in case anyone is experiencing weird issues with your compiler and/or simulator, Florian suggested cleaning out the caches....you need to do this for your iMac, Xcode, and your mobile devices. Further, the websites above identify more cleaning targets that will help keep you clean and free from bugs. It appears that old versions of projects have data that is used again in the build/compilation, even when you have replaced it and have no interest in it....

take care...Dixie
