<p>I know and have Xcode, but I was wondering if there were any other complete development environments that support Objective-C? I'm not looking for solutions with vim or emacs, nor editors like BBEdit that support syntax highlighting, but a full fledged IDE with:</p>
<ul>
<li>code completion</li>
<li>compilation</li>
<li>debugging</li>
<li>refactoring</li>
</ul>
<p>Extra points for being cross platform, supporting vi key bindings and supporting other languages.</p>
<h3>Note:</h3>
<p>I've updated and accepted my answer below as Jetbrains has released Early Access for <em>AppCode</em>, their new Objective-C IDE. Since this has been a fairly popular question, I thought it worthwhile to update the information.</p>

I\'m going to check it out anyway.</p>\n\n<p>Textmate has a couple screencasts for Objective-C (<a href="http://macromates.com/screencast/objective-c_part_1.mov" rel="nofollow noreferrer">here</a> and <a href="http://macromates.com/screencast/objective_c_part_2.mov" rel="nofollow noreferrer">here</a>). It is Mac only, but otherwise looks pretty good. It is hard to tell from the screencast how strong the integrated support is as it seems to just have a lot of scripts to handle the code. Also, I can\'t tell if it does true code completion or just expansion for snippets.</p>\n\n<p>So it doesn\'t look like there is anything out there that hits everything. I\'ll probably do most of my development on Mac, so I\'m thinking I\'ll try out TextMate with XCode to see if it is any better than straight XCode.

Unfortunately I think that due to the relative obscurity of the Objective-C language that nobody has ever bothered producing such a full featured IDE for it.  Until now, and we only have Xcode.</p>\n\n<p>Using JBuilder I fell in love with the auto-completion and displaying the function 'hints' on the screen while I type.  I am that sort of person who remembers the 'ideas' better than the actual syntax and really benefits from knowing right then and there that the code I typed was correct, not having to find out a minute later at compile time.  And then to have to try and figure out if I just misspelled something, or if I truly made a conceptual error due to a misunderstanding of proper use of the language.  Code completion and hints have always saved time on this for me.</p>\n\n<p>I know some people may look down on this and say the feature is unnecessary if you know what you're doing, but I never claimed to be better than anyone else.</p>\n\n<p>I may have to just give up and try and get OS X running on my PC.  Which doesnt bother me in the least, just the rebooting to go back and forth to windows.  I've tried to run it virtualized under VMWare but XCode kept crashing :(  That reminds me I am going to google 'leopard vmware' and see if any progress has been made in that area.</p>\n\n<p>Another problem in designing a full code-completion system with objective C is that the syntax is a little more forgiving, I dont know the exact technical term (strongly typed?) it is much harder to say exactly what sort of object belongs in a certain parameter and ANY object can be sent ANY message whether it implements that function or not.  So you can spell a function name wrong, but it doesnt necessarily mean you made a syntax error... maybe you mean to call a function of that OTHER name and you just want nothing to be done if the function is not implemented by your object.</p>\n\n<p>That's what I would <strong>really</strong> like to see for Objective-C, is an IDE that once it notices you are sending a message to an object, it displays a list of methods and function definitions that the object is <strong>known</strong> to accept, and walks you through filling in the parameters.</p>\n"}, {'answer_id': 2025821, 'author': 'Friedrich', 'author_id': 15068, 'author_profile': 'https://Stackoverflow.com/users/15068', 'pm_score': 1, 'selected': False, 'text': '<p>The short answer is: No. There are thousands of IDEs but Xcode is the only one which you seriously can name IDE.
