I have a custom application which requires a bunch of things to be set up before it is run. I want to add it as a build phase so I can use it when I do "Build and Run" but not when I do "Build". How do I check it in a shell script which is run as a build phase at the end?
Please don't ask why
I don't even have a Mac, so this is purely my imagination. I assume, XCode allows you to specify which executable to run when "Build and Run" is used. If so, you can write a simple batch file, which will perform all the required setup and then run your main app. Point XCode to that file and you're fine.
Don't know if there is something special triggered for "Build" vs "Build and Run". You might want to check out a different build configuration. Projects come with a Debug and a Build configuration, maybe add a "Config&Build" that has some flags set. If the flag is set then do your setup stuff. Then it would be easy enough to switch configurations. I do something similar with my debug output and only turning them on in the debug configuration.
