Is there some resource out there that describes low-level OS information for iOS? Looking over the apple docs, it seems as if they don't go into too much detail about how the kernel might manage processes, etc.
So, to be more precise, I suppose I am interested in learning about how processes are handled by iOS.
Where might I go to look for documentation on this? Is it even out there? Or is it encompassed in some other information (i.e. since it is based on Unix, the kernel implements similar process management)?
This is pretty much undocumented, because Apple wants the freedom to tune the system at a low-level, and you can't do that if a lot of apps start using low-level interfaces.
That said, since iOS is based on Mac OS X, you might learn a lot by studying the open-sourced parts of Mac OS X.
The book Mac OS X Internals gives a lot of deep system level info about Mac OS X, too.
No deflections please. It’s never ok or acceptable to prevent security audits by blocking access to required information. iOS devices are used by many different people and organizations with a variety of security policies and needs. This becomes a trust issue. Needing a far better explanation of why Apple should be trusted by default. Don’t be quick to leap into a “if you don’t trust Apple then don’t use their products” posture. For many orgs that would trigger a “use or possession of any IOS based product is forbidden on premises”.

I am using an esp32, with the function esp_https_ota, but i think the situation applies in any iot OTA.
Let's take the situation:
I release a release whose firmware badly controls subsequent OTAs
I would like to release a patch ... but I can't because I broke the OTAs
Are there any tools or best practices to address this?
NB: I am not looking for a "solution", I do not want to remedy a problem that has already occurred, I would simply like to understand good practices.
The easiest way is to work with a beta release; in my devices you can choose a firmware location; the regular and a beta/test location. Last only for devices in reach of course. Will prevent most of the problems.
And the function you intend to I guess is the app rollback function. Although it has some possible security issues, if you run the program and let it do some easy tasks to verify basic function and consequently validate the image, 99% of your problems is solved.
To tackle the last percent I added OTA over SD, so people can put a firmware image on sd card. In my opinion wifi/https takes a lot of buts and ifs to work.

I am iOS developer. I am new with doing object tracking feature. I have searched many links based on tracking real objects. But I have found many links like image tracking, image matching and all. Likewise I would like to track the real world objects.And also I have gone through a site below:
http://developers.arlab.com/me
It helps a lot for tracking images, image matching etc. But not specified any object tracking. If anybody suggesting good tutorial or having any sample source code of object tracking, please share.
Advance Thanks for your support.
You can use the OpenCV framework for Object Tracking. There are many nice tutorial and documentation on internet.
Below i have listed some.Please check if this helps you
Official Site

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?

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.

Should HIPAA complinace not allow offline storage in Mobile Native Applications??I dont know if already there is this sort of regulation in HIPAA. I assume there is no such thing.
If you feel this question need not be asked in this forum, I request you to completely read this and suggest a programmatic solution for this problem.
Main reason why this came up was that all of the security considerations regarding the Mobile development may be specifically in iOS seems to have been hacked in to once a device is jailbroken or rooted.
I came to know that hardware encryption is hacked.
http://anthonyvance.com/blog/forensics/iphone_encryption/
Then there are questions on iOS 4's encryption techniques.
People claim, Key chain access in iOS can be compromised if the phone is rooted.
Only thing I think which has not met with any skepticism is the sqlCipher.
If you could find any flaws with SqlCipher , please share it.
And I think that, until people find a theft-proof way to manage offline data in Mobile Phones, people can refrain from making offline features for EMR apps where HIPAA compliance is mandatory.
It can be argued that, any system can be hacked when people are desperate to hack it. But I feel Mobile devices can be an easy target. You can lose it as you lose your Handkerchief.
Please share your views.
I agree with bshirley. Your surface of vulnerability is much greater if you are storing many records about many people on the device. But if you are only storing limited info about one person temporarily - as when conducting a query for prescription info or gathering information about a current health problem - then the risk is much lower. Of course you also need to consider whether the hacked phone presents a security risk to the online data, that is, does the app on the phone enable a wrong user to access protected data online?
Here's an application note you may find helpful: "Formotus™ Mobile Solutions and HIPAA Compliance"

I work for a mid sized Architecture and Engineering firm, our sub group focusses on developing tech solutions for engineers, mappers and technical managers. So we're heavy on desktop based apps for GIS and Civil/Env Engineering (some web). The company sells the services that our Engineers and mappers produce and our team develops tools that aids in them being more productive, efficient and help in adding value to their decesions and products, we DONOT sell the technology.
We are going through growing pains where initally we used to be extremely responsive and could rapidly prototype apps for engineers which immediately brought budgetary savings. That mindset has worked for us in the past. But this year we won a huge contract and our client base has basically quintupled (5 times?). What we are finding is that this rapid prototyping culture is hurting us, where project managers have started to expect short response times for tool development and robust production ready tools for all our engineers and gis analysts. We've grown organically and now it seems that we are running into these issues were it appears we have to scale back our speed for more stability.
Is this a legitimate tradeoff? Is there a win-win?
How does one push back the engineer, project manager and analyst when they are our clients, they fund us and yet we need to be able to push back and tell them that if they want stability they have to be realistic about time frames?
This isnt Microsoft Word, these are specialized GIS software and Engineering models with a ton of interop components for other industry standard models, they arent idiot proof tools, they need informed inputs and we can only test things so much.
Has anyone dealt with similar growing pains? Recommendations/advice on a communication stance, books, blogs?
Appreciate the time!
The best thing to do here is to start to be honest about the strain and show, in writing, what exactly is happening and who all has demands on your team. You need to show the hours that all of your tasks are taking and who is doing them and be able to show that level of status.
This merely give you some sort of proof about what's happening. At that point you can start to do the re-organization you need to do in order to start to support growth.
