I'm very familiar with running a program in an IDE or closed system in order to allow quick access and quickly fixing the code. What I'm not used to is these "certificates". I'm just picking some open sources Xcode friendly programs just so I can learn. I'd think that if it has an Xcode project file then it should compile. Most of them, instead, it stops on the state of these certificates.
