Nimesh,
Thanks for taking a look at this. I agree it seems I must have a missing project setting, or be doing something else wrong.
I've attached 2 projects:
1. InfoTemplate is a class example from the Esri "Mobile GIS: Getting Started with the ArcGIS API for iOS" Virtual Campus class. If I put a breakpoint in mapView:didClickCalloutAccessoryButtonForGraphic:, then Xcode crashes.
2. MapViewTest1 - A breakpoint in mapView:didLoadLayerForLayerView: causes this one to crash Xcode.
Thanks again,
Dave
