RestKit version(0.25.0) I am using in my app uses AFNetworking1.3.4 which in turn uses NSURLConnection. But Apple deprecated NSURLConnection in iOS9. Is there a latest RestKit version available that I can use in my iOS9 app or will the same version(0.25.0) work on iOS9 also?
The same version works on iOS 9 also.
But unless you are prepared to help update RestKit, you might consider it a red flag to depend on a library that requires deprecated iOS APIs, because who knows if those APIs will still be available in iOS 10?
It looks like the latest work is focused on removing the AFNetworking dependency and using NSURLSession directly.
I would expect NSURLConnection to be around for a long time to come, as it is very broadly used. It will not, however, get any new features, in all likelihood.
Either way, it works fine in iOS 9.

I'm writing an app in SWIFT 2.0 using Xcode 7, but my deployment target is iOS7.
While writing and OptionSetType struct, I've seen in the Quick Help that the availability of this protocol is iOS9.
In the "header" and official documentation nothing is mentioned, but I'm really wondering if this protocol is also available in lower iOSes versions since SWIFT 2.0 should be fine until iOS7.
Since all swift standard library ships with your app to AppStore, all this protocol will be available on iOS 7 and above.
I've created an iPhone game which utilizes some code from an old version of the Cocos2D iPhone game development framework and I've got a wee bit of a problem running it on iOS 7.
The version of Cocos2d from which the code was used was probably 0.98.
The actual class is called QuadParticleSystem (in newer versions it's been deprecated by CCParticleSystemQuad).
The actual issue is that the game runs fine on iOS 6 and below. It even runs fine on iOS 7 if the deployment target is set to iOS 6.0 and SDK version set to 7 (at least when put on the device directly using XCode).
The problem is that when the game is uploaded to the appstore, Apple seems to strip out the whole iOS 6 compatibility thing and the particle emitters fail to show up among other things like alpha transitions, invisibility etc.
(They initialize correctly and everything, but they simply DO NOT render).
I've considered (and tried somewhat) upgrading the Cocos2D version, but due to the old third-party frameworks I've used for other things there is a hell of a lot of linking/dependency/deprecation errors which could take forever to fix (if it's at all possible, which I doubt) In other words, I've wasted too much time on the project already and am looking for a quick fix.
If no one knows any solutions could anyone at least direct me to docs where I can see how to create/insert a new particle emitter system in the existing code?
I've thought about using SpriteKit's native emitter system, but I don't know how to incorporate it within the current code (as I've never had dealings with SpriteKit) and am not sure if it's even possible.
I've also thought of maybe upgrading the GL ES framework within that old version of Cocos2D just in case Apple have killed off some functionality of older versions of OpenGL. Then again that could take a while.
We're building an iPad app and don't plan to use any APIs that are not available in iOS 3.2. Our deployment target is already set to 3.2, but I would like to set our base SDK to 3.2 so that we get compiler warnings/errors if we accidentally invoke APIs not available in 3.2, rather than runtime failures.
Is this a good idea? If so, is the 3.2 sdk still available for download, and will older sdks work with newer XCode versions, like 4? Thanks.
There's no guarantee Xcode will support older SDK versions but as an example the current install of Xcode 4 goes all the way back to 3.0. I would drop 3.2 if I were you (few iPad users are on that; most iOS apps enforce 4.X in the App Store so I'd bet most people have upgraded) but if you are going to support it perhaps you should consider using conditional code for different OS' versions.
I am just starting iOS/iPhone development and I would like to start using XCode 4 instead of XCode 3.2. Is XCode 4 stable/feature complete enough for beginning iPhone development or should I stick with XCode 3.2?
I have run into far too many problems using beta versions of XCode, especially since you can't really have two versions of XCode one the same system. Apple already has a history of releasing things to developers before they are truly ready (just look at iAds for the iPad which were released months ago and have yet to deliver a single ad). So, if even Apple isn't ready to label XCode 4 as ready-to-go then you can rest assured its not really ready to go.
I recommend sticking with 3.2. That's what I'm doing until XCode 4 is officially supported.
Using XCode 4 calls everything you do into question. Having a problem with an API? Maybe it's XCode, maybe its your code, maybe its a bug in the API. You just don't know.
I would say no, it's not ready. I tried using it as my main development environment for about a week, and eventually switched back to 3.2. For one thing it crashed fairly regularly, but I could get passed that.
The big thing that caused me to switch back was a bug where the iOS simulator would think that certain resources existed in my app that didn't. Deleting the app from the simulator didn't work, cleaning the project didn't work, and deleting the derived data folder didn't work. Since it's not officially released, finding help for problems like this is a pain as well.
This is just one instance of the kind of problems you'll run into while using it, so I'd recommend avoiding it for now.
You can use Xcode 4 if you do not plan on using the current version (Preview 6) for submitting apps to the App Store.
iOS Dev Center:
Xcode 4 Developer Preview 6 includes
iOS SDK 4.2, bug fixes, and additional
features. To compile submissions for
the App Store, continue to use Xcode
3.2.5 and iOS SDK 4.2.
I have iPhone application in the App Store. Do I have to compile my app with iOS 4.2 SDK in order to allow it run on iOS 4.2 devices? Or compiling using iOS 4.2 is required only to allow using new features of new iOS?
I will appreciate if you can clarify this issue...
Thanks!

Do I have to compile my app with iOS
4.2 SDK in order to allow it run on iOS 4.2 devices?
No, it will run on the new firmare just fine. At least if the new firmare does not reveal some bugs in your code (which happens).
You don't need to recompile it to let it run on newer OS versions, but like you already guessed, you need to recompile it when you want to use the newer features (eg. AirPlay, "Multitasking" etc).
The old version should still run.
The app might not play well with new features like multitasking on iPad, so it is worthwhile trying to get some testing and feedback done as soon as you can in case there are issues.
If you download the XCode 4 pre-release from the developer portal, you can use the new static analyser to look for problems in the code: this is not just for SDK issues but also things like memory leaks.
Apple recommends that you always compile with the latest SDK, even if you are targeting older versions.
Unless you run into a specific issue that is causing incompatibilities, it is wise to take this advice. A lot of small bugs and performance issues are fixed with each new iteration of the SDK.
That being said - you can continue to use the older SDK's, and Apple will still accept the apps you build. For mature apps that are only going through minor tweaks, this is probably the safest course to avoid introducing new bugs.
