Anyone got a fix or even a clue. </p> <p><strong>Update:</strong> The <code>user header</code> search paths are set to <code>${BUILT_PRODUCTS_DIR}</code> in all configurations. It builds fine using any configuration except when archiving. </p> <p><strong>Update 2:</strong> <code>Merchant.h</code> is a Core Data class that is auto-generated and therefore inside <code>.xcdatamodeld</code> package, however the headers are all copied to the public headers directory when the library is built.</p>
