What I do is: Write code in Cerberus, hit Compile and Run, and that's it. I don't mess with Xcode, app settings or anything like this, since I don't publish that, I just use it on one computer. So I have no idea about all this. The documentation is very frustrating for me, since it's targeted to someone who already knows all this. There should be at least an example for every function, method etc.
Monkey X and now Cerberus X has nothing to do with BlitzMax. These are different products from BRL.I'm using this since it has been Blitzmax. So of course I don't want to change to a different tool.
If you want to look and/or files that are created during the build or after you run your app, you need to dig into the app-bundle at least. and so you need to make yourself familiar with Apples way of doing things. If you just want to run apps, then of course, most will work out of the box.It has never been neccassary to mess with Xcode or anything like that.
