Sometimes, when I mess something up in Interface Builder, I get an unhandled exception at runtime and I get thrown back to Xcode. The only thing I see is a single line "uncaught exception" or something ...

I'd like to start developing applications for iPhone, but I'd really like to use OCaml rather than Objective-C. After some googling, it seems like this is definitely possible, but I haven't found any code snippets which actually compile. Is it possible to write iPhone apps using OCaml? If so, could you provide a snippet demonstrating ho...

I have developed a few Delphi Win32 (currently using D2007) applications, which revolve around note-taking and idea development. I'd like to be able to pull the notes written on the iPhone's little "notes" app into these apps (which store their data in a database). One-way importing would be fine for now. Is this possible? If so, what ...
