My product is a System Preferences Pane. Its principal class is MyPrefPane and is defined correctly in the Info.plist file under NSPrincipalClass.
The bug I am seeing happens when trying to install a new version over the top of an older one if (and only if) System Preferences is closed or System Preferences is open but the older pane has not been clicked on (and is thus not loaded). I get an error that my pref pane can't run on an Intel Mac and console reports: System Preferences[10232]: -[MyMinorClass initWithBundle:]: unrecognized selector sent to instance 0x7fc60be96170 System Preferences[10232]: [NSPrefPaneBundle instantiatePrefPaneObject]: error occurred during instantiation. It seems like System Preferences is trying to init my pref pane by loading a minor internal class instead of my MyPrefPane class. In Xcode Build Phases under compile sources, I noticed that the first two items are: MyMinorClass.m MyPrefPane.m If I reverse these, and compile MyPrefPane.m first, the bug is eliminated. Putting any other class before MyPrefPane.m results in System Preferences making the same attempt to call the first-compiled class with initWithBundle: Why does the compile order matter? I found a similar issue here: http://stackoverflow.com/questions/31373144/xcode-source-compiling-order-iss ue He solved it by rebuilding the project. I have just spent 8 hours rebuilding this complex project and still get the same results as before (this Xcode project has existed since Xcode 3) I am unable to reproduce this on a simple Xcode PrefPane template. Any ideas? I am not sure if this is an Xcode issue or something in the OS. For now of course all I can do is make sure the principal class is compiled first.
