I've been trying to work through a tutorial which I foresee will be very helpful to my current project, but it was target at XNA 3.1. Thus, many sections of code (which the author does not explain too much) are now obsolete. Here's a pastebin of the file. The main thing that sticks out to me is the GraphicsDevice.CheckDepthStencilMatch function. I can't seem to find out much about it. Is it even necessary anymore? As you can see I've commented out some of the sections which I think are no longer required.
Check out XNA 4.0 method: GraphicsAdapter.QueryRenderTargetFormat Method
The description for it:
Queries the adapter for support for the requested render target
format.
I believe this is what you're looking for.
Let me know if you need specific code sample or anything else.

New to Swift, couldn't find an answer to this with a reliable source.
I have some commented code, but would like to know if they are removed when compiled/run in Debug/Release, and if this is enforced or can be turned on/off.
If they are indeed removed, what about those instances where I really need them to be inside, e.g. some framework or something?
Thanks in advance!
If you create inline docs in a swift package, they're available to the consumer. If you provide a Docc asset, that will also be available to the consumer.
If you create a binary, that depends on how it's created and distributed.
Unless there is a security concern not to share the source code, I would do a vanilla SwiftPackage with documentation comments.
I have created an iOS mobile application. Is there a way to generate a UML class diagram for the Swift programming language?
I have tried Omni Graffle, but it keeps saying that the project doesn't contain Objective-C interfaces. And Omni Graffle only does this for Objective-C.
I remember looking at this question a while ago and was disappointed that there wasn't any tool like this so I created one myself with the help of a colleague. It's free, it's open source, it's looking for contributors...
https://github.com/yoshimkd/swift-auto-diagram
And here's a tutorial on how to use it (don't worry it's very simple):

Happy diagraming :)
The answer unfortunately is: you can't do it. At least not automatically. Swift as compiler itself has enough flaws left. Leave alone some tool will be able to swallow any Swift code. Your only alternative is the good old manual way.
I know that Enterprise Architect has a possibility to define a language syntax based on BNF. But Swift is (again unfortunately) not context free. (In fact it's so context sensitive that it often swallows its own rear.) So that won't work either.
P.S.: Now that Swift is open source someone might take the opportunity to tap the compiler's output for the class interfaces. I guess that should not be too difficult, but it's a lot of work still.
Inspired by swift-auto-diagram and similar open-source tools I started to work on such utility with the goal to write it in Swift (to make contribution easier by Swift developers) and to integrate it in Xcode and the Swift ecosystem.
Xcode extension: https://github.com/MarcoEidinger/SwiftPlantUML-Xcode-Extension
You are able to generate a class diagram from selected lines of code or from a whole file displayed in Xcode. The class diagram will then be opened in your browser. There you can modify the diagram with PlantUML notation
To generate a class diagram from multiple source files you can use the underlying CLI tool and Swift Package: https://github.com/MarcoEidinger/SwiftPlantUML
There is a size limitation to the visible diagram content (but you can delete content in the browser with PlantUML notation)
Hi, I'm just wondering how you could obfuscate functions in iOS binary?
If you tried to reverse iOS binaries using tools like ida you will see part of the binaries have obfuscated functions like all or partly named sub_xxxxxxxx but the other have human readable functions
Someone said, add those lines to the top of your header without any further explaining:
#define SecurityClass ah7p
#define checkCopyProtection xcyc
What the methods used to secure your App?
Sorry for the dumb question, but I'm new there and I ended up with no answer explained what I need.
There are a couple of ways to obfuscate an iOS binary.
Open Source compiler named llvm-obfuscate (https://github.com/obfuscator-llvm/obfuscator/wiki) It has some nice features to obfuscate during compilation. You are replacing your default compiler with that one.
There are for Windows of course VMWare oder Themdia that can post process but that is not the case.
Besides that I just know one more which is Liasoft antispy. It is a very advanced anti analysis toolkit that allows you to encrypt functions and much more during compilation using mixed Objective-C and C++ code. ( https://www.liasoft.de/en/products/antispy/ )
Not sure if one of these is the right one for you. Except these things you are pretty lost since Objective-C is a compiled language with lots of metadata.
Hope I could help you, this is my first post.
If you only care about obfuscating method names then the easiest way is to write relevant parts of your application in C or C++. For instance, you can rewrite your SecurityClass as a C++ class instead of Objective-C class. This will not make your code reverse-engineering-proof, but it will at least raise the bar a bit. (NOTE: I'm not saying this is the right thing to do from software engineering point of view, though).
If you need to obfuscate code, then you are in a search for a tool that can do this. There are several such tools, both commercial and free. One project for doing exactly this is obfuscator-llvm.
How shall I write (what style) the comments for public methods and properties in my classes so they would be visible in Quick Help window the same way they are for built in methods?
The absence of strong typed array in iOS creates bunch of issues for me, especially when a method accepts a NSArray*, if I wrote it 6 months ago, then I need for sure to go in that method and check what are actual types that must be stored in that array.
Thx
Yes, you will have to regenerate the documentation whenever you want a change. Xcode does not pick up documentation on the fly based on your comments like Visual Studio can. This is confirmed by a comment in the question I linked to:
Xcode's Quick Help uses your installed documentation sets to display its contents. Unless you create and install a documentation set for your classes, all Quick Help displays is a link to the header file where you declared the class, method, or data member.
Appledoc seems to be your best option. I know it's not the answer you're looking for, but it doesn't seem too bad.
Is there any centralized repository of useful Objective-C / Cocoa libraries as there is for Perl, Ruby, Python, etc.?
In building my first iPhone app, I'm finding myself implementing some very basic functions that would be just a quick "gem install" away in Ruby.
There's a project for that! It's called CocoaPods!
Homepage: http://cocoapods.org/
Source: https://github.com/CocoaPods/CocoaPods
Unfortunately not :(
There are some very useful sites however. I find one of the best is cocoadev.com as it contains lots of useful information about many of the more obscure classes usually including snippets of code to do some really cool things :)
Maybe we (the cocoa community) should look into building something like this!
Oh and I just remembered this site cocoadevcentral.com which is also very good for starting out with cocoa.
Daniel mentioned http://cocoadev.com.
More specifically, check out http://www.cocoadev.com/index.pl?ObjectLibrary.
"This page is for tracking re-usable Cocoa classes that can be mixed, matched, and dropped fairly easily into existing Cocoa projects to add useful functionality."
I'd be interested in what kind of "basic functions" you're having to implement. There's actually quite a lot already there in the provided libraries, and I wonder if you're just not finding functionality that's already there...
There's a new index of reusable code for Mac OS and iOS: Cocoa Objects
I might be confused or missing something here... But doesn't apple provide all the Foundation / Cocoa / AppKit / CoreAudio / Qtkit / etc libraries that should provide all of the very basic functions you are looking for?
Other than what xcode comes with or is on the apple dev site, there are no centralized repo's for Cocoa.
Google Code also has some objective C things up. It depends on what you are looking for...
Also see GitHub, many useful Objective-C projects, especially re iPhone. See activerecord & cocoaoniguruma, for instance.

http://github.com/search?q=objc
Google has Google toolbox for mac which got me started unit testing my iPhone application which was the main thing I found missing.
