Is it possible to compile iGraph, graph layout library for iOS?
I haven't. I don't know anybody who has. But I've also never heard of it before.
The website claims it is written in C/C++, so in theory you should be able to get it running on iOS. You may need to make some modifications.
Looking more closely at the documentation, it appears to be a plain C API (even better!) so it should be fairly easy to compile for iOS. You will probably have to edit the Makefiles to have it cross-compile for ARM (instead of Intel).
However, the source code is published under the GNU GPL. There are clauses in the GPL that conflict with clauses in the Apple Developer Program Agreement (I forget the specifics but it should be easy enough to research). This means that if you got it working in an app, you couldn't put it on the App Store without either Apple or the iGraph developers offering you different terms.
Not sure about iGraph, but I've been thinking of trying Core Plot.
It's a graph plotting 3rd-party iOS framework.
Not a lot of documentation, but you can see some apps that already use it if you browse their site.
Not sure why you got voted down. Happens.
Edit:
Oh, in that case, this question might help: https://stackoverflow.com/a/5074186/1126783

I made an app and I don't have the knowledge to add a few things that I want. I found a developer online. How can I protect my app to make sure it doesn't get stolen?
If you give him your source code, no technical measures can stop him from stealing the source code. If he were local to you, you could require him to use a locked-down computer in your own office, but I don't think that is an option for you.
If your app has substantial non-code assets (graphics, sound, databases, etc.) you could give him only the minimal subset of assets necessary for testing.
If the app talks to a server you control, and you don't also give him the code/data to set up his own server, then him stealing your code may be less harmful.
Other than that, you need to consider legal enforcement, not technical enforcement.

With the announcement release of Swift as open source a question came to my mind. Apparently the language/compiler supports Linux besides the obvious Apple different operating systems, but what kind of apps can really be created in Linux?
What type of apps can we create within Linux using Swift, iOS, OSX, etc. apps or only Linux apps?
Or better yet, since this may be to early the question could be... what kind of apps are we going to be able to build in Linux in the future?
Swift is a programming language, not to be confused with a software library, such as UIKit, or an Integrated Development Environment (IDE), such as Xcode or Microsoft Visual Studio.
To put it succinctly, I think in the near future we can only expect to write in Swift the kind of applications we are able to write in C and C++ on Linux. The downside of Swift: it's tricky to integrate with C and C++ code. See, e.g., http://www.swiftprogrammer.info/swift_call_cpp.html and http://www.swiftprogrammer.info/callback_void.html. The advantage: it's simpler to use than C and C++.

Is there any standard way to build developer, just making the developers understand the code easily after delivering, if you have sample it's better
If you want to know how to make your code better, you need to read about SOLID and other object-oriented design patterns.
There are no official Apple developer programming style guides.
I.e.: no official "Programming Standards" exist.
Standard only exist in terms of UI, external appearance of your application.
Normal software development criteria apply:
commenting
using software patterns appropriately, as pointed out in another answer, SOLID makes a lot of sense. Just in order to understand Apple Frameworks you need to know software patterns: delegation, visitor, proxy, etc.
document requisites and change requests, api and architecture if the app is complex
don't rely too much on bug tracking, these tend to be abused (change requests marked as bugs) and might add too much complexity of their own (JIIRA).
your organization may adopt an existing programming "quality standard" and adapt it to iOS development. ITIL is and ISO are usually overkill.
Sometimes it makes no sense to over-optimize and over-engineer everything, including your code and programming standards.

I've spent a whole day trying the different solutions one can find by Google-ing this.
Using Xcode to downgrade
Downloading the firmware image and providing it to Xcode
Using iTunes
Using an old computer that the phone was sync'ed to back in 2009 (funny enough, I have two of them)
Using the iRestore and libusb
So far the only thing I've seen is the phone getting stuck in DFU mode or a message saying that it can't be downgraded (I forget the exact language).
It would seem that Apple would provide for a way for developers to do this sort of thing without this much pain an agony. I have eight iOS devices, four of which are permanently devoted to development, two iPods and two iPhone 3GS. The two iPods stayed with iOS 4.x. Both 3GS's where accidentally upgraded to iOS 5. I wanted one to stay with 4.x for the time being.
Do I have any options beyond what I've tried?
Apple: A little developer love would go a long way here. It's enough to have to deal with all the stuff that breaks from release to release of the OS and Xcode. At least make this easy.
Pretty please?
With sugar on top?
(Had to try)
The question was marked closed. I don't understand why.
According to the FAQ:
"Stack Overflow is for professional and enthusiast programmers, people who write code because they love it. We feel the best Stack Overflow questions have a bit of source code in them, but if your question generally covers …
a specific programming problem
a software algorithm
software tools commonly used by programmers
practical, answerable problems that are unique to the programming profession
… then you’re in the right place to ask your question!"
This question relates to software tools commonly used by programmers working on iOS devices.
And, in fact, it is a huge problem due to the fact that it impedes proper testing on the platform. Perhaps someone in this community has better ideas that can be brought to the surface. That was the intent.
"Questions on Stack Overflow are expected to generally relate to programming or software development in some way"
I think this question definitely relates to software development.
Re-open it please. This is a big problem.

Recently, I found an interesting Wiki/CMS/Database hybrid called Wagn, where the most important unit of information is the 'Card'. That terminology immediately made me think of Hypercard. As expected, there is some "Hypercard-ness" in that application.
Do you know of other web applications/frameworks with that "Hypercard-ness" thing, or if its successor still must be invented?
Note: I insist on web applications because I already know the desktop ones.
Check out Runtime Revolution at http://www.runrev.com they have a language/IDE that is the spiritual successor to HyperCard. They also have a product in beta called RevWeb which is a plugin not unlike Flash that is able to execute stacks.
Now more on the web framework front, checkout Rodeo at http://alltiera.com/ which is a HyperCard like web application that generates HTML/CSS/JS stuff for you.
I am a customer of Runtime Revolution but I haven't used Rodeo so I can only help with building web applications using RevTalk (like HyperTalk) and not with Rodeo.
There was http://tilestack.com for a while. Sadly it closed down again. It even imported HyperCard stacks.
I have found that quote from Dan Ingalls in the book "Coders At Work" (p.382):
"A decade or two ago there was Hypercard [...] It's really strange that that whole experience didn't naturally go right into the web. I think there's still a role to be filled there with tools as simple as HyperCard and as immediate as the web. It would be cool if it went that way.".
If one of the inventor of Smalltalk is asking that question too, I'm almost sure that there is no valid answers...
Anyone interested in inventing that future?
Google's AppEngine is being called the web Hypercard.
