WARNING: Almost all questions about development or app distribution are off topic here. See the Help Center for details. Xcode is Apple's official software development environment for Mac OS X and iOS
Questions relating to programming generally belong at Stack Overflow where programming questions are best asked and answered.
Ask Different focuses on consumer use of Apple released (beta and production)software (please - no NDA topics). Questions on how to install or launch Xcode are fine here. Also, Automator and AppleScript questions that relate to Xcode are also welcome here. When the problem only relates peripherally to Xcode in that it's ultimately a programming question (Algorithms, language specific errors, what you do with Xcode in the service of making a program) then we will likely vote to close those "code-level" questions and direct people to the many programming centric places on the network.
