Can I update my iphone application for iOS7 only? - iphone

I have developed application for iphone4/5 with iOS 7 support. Recently I found issue in that and wanted to update application only for iOS7.
Does Apple allow me to update application for iOS 7 only? Do i have to give support for iOS 8 right now?

If you submit with Xcode 5.1.1, you'll compile with iOS 7's SDK (and your app will behave as it behaves currently).
If you submit with Xcode 6.0, you'll compile with iOS 8's SDK (and you'll have to update your app due to new API and possible bugs).

use Xcode 5.1.1 if you want to fix issues only for iOS7 for time been and submit the app..but users might face issues if they are using iOS8 on their devices.

if I understood you correctly, I believe you should check in code for the user's iOS version and then update based on that.
See How to check iOS version? how to do that.

Is there any way to develop iPhone app under iOS6 that targets iOS 3.1.2?

I have a very frustrating experience with recent iOS development. The situation is:
I have developed an iPhone app which targeting iOS 3.1.2, and I am about to submit to AppStore.
What I received from Apple after submission is:
I have to support iPhone 5 tall screen.
The reject message is:
iPhone 5 Optimization Requirement
To support iPhone 5, I need to update the UI and include a launch image: Default-568h#2x.png
After having the Default-568h#2x.png included, Apple rejected my submission again with reason:
Invalid Launch Image - Your app contains a launch image with a size
modifier that is only supported for apps built with the iOS 6.0 SDK or
later.
OK, I am kind of stuck, Apple force me to support iPhone 5 screen, yet, it doesn't allow me to upload app under iOS 6 with iPhone 5 tall screen support.
So I try to compile the code with iOS 6 SDK, then what I find is in order to support iOS 6 I need to have XOS 10.7. Mine is 10.6.8.
To support 10.7 I need to upgrade my Mac to have 2GB memory and i3 duo core CPU and brah brah brah brah...which I don't have at the moment.
So, my question is:
I have XCode 3.2.2, XOS10.6.8, I want to develop iPhone app for iOS 3.1.2 and able to publish in AppStore, how can I do it?
Thank you.
Regards,
Apple will not accept an app targeting an iOS version that old. I don't think they will accept anything less than 5.0 anymore (might be 4.3 but I doubt it).
Sorry, but Xcode 3.2 is years old at this point. Apple simply doesn't support this. iOS 3.1.2 has such a negligible install base that there is almost no reason to target it any more. To support the latest features of iOS (e.g. iPhone 5 support) you need to be building apps with the latest SDK, and you will need to upgrade your development machines and Xcode. You have no choice.

We intend to support the iPhone 5, do we need to upgrade Xcode to v4.5 and use the iOS 6 SDK?

We want to update our game to support the iPhone 5.
Do we need to upgrade Xcode to v4.5 and use the iOS 6 SDK??
[edit]Apple is now explicitly rejecting applications submitted with the iOS 5.x SDK and iPhone 5 default images, saying "Your app contains a launch image with a size modifier that is only supported for apps built with the iOS 6.0 SDK or later."
Old answer :
Yes you can use Xcode 4.4 or below to support iPhone 5.
The iOS (6) will run an app in letterbox mode if there is not a 640x1136 splashscreen image in your resources. The image must be called Default-568h#2x.png (if your splashscreen is Default.png in your Info.plist).
So just add this image on your Xcode project whatever version it is, and the app will run in full screen mode.
This being said, there are chances that Apple will not let you install an app compiled with Xcode 4.4 or below on an iOS 6 device (and of course no iPhone 5 simulator for Xcode 4.4 and below). [edit] As told in the comments, yes, you can install on an iPhone 5 / iOS6 with Xcode4.4.
All apps created with older SDK works perfectly on newer iOS versions, so iPhone 5 should also run every existing app without any problem, so you don't need to use the iOS 6.0 SDK to support iPhone 5.
I think you mean to ask to support iOS 5. If that is the case then you really do not need to upgrade your Xcode version. YOu can use iOS SDK 5.0 or iOS SDK 5.1 which contains Xcode version 4.2 and 4.3.
You really do not need to use iOS SDK 6.0 beta. I hope this may help you.
All the information about iOS 6 are under NDA, and the iPhone 5 is not even announced.
But there are rumors, that the iPhone 5 will have a screen resolution of 1136*640. There are hacks for Xcode 4.4.1 out there that make it possible to create that screen resolution in the iPhone simulator. So, I think that would be a viable way for testing the rumored new resolution.
Regarding iOS 6: if you are a paying iOS developer, you can download iOS 6 to test your app against it (We don't talk about products under NDA here).
You can use this receipt http://0xced.blogspot.co.at/2012/08/prepare-your-apps-for-new-iphone.html for start iOS Simulator (iOS 5 only) with new screen size.
Yes, You need to update your Xcode to build for iPhone5. Do the following steps for this:
Download Xcode 4.5 with iOS 5.1 SDK.
Build your apps with Xcode 4.5.

iOS app maximum iOS version support

I have developed my app in Xcode 4.1 and iOS SDK version(Base SDK Version) is iOS 4.3 So, will this app run on iPhone with iOS 5 and/or iOS 6 or not?
I think the app can be run on a higher version of the OS than the Deployment Target. Is this right? I appreciate any help.
Yes, your app will run on anything that is iOS 4.3 or newer. That is, assuming you aren't using any depreciated methods that are removed from a future iOS release. You can check if things have been depreciated/removed through the documentation.
It doesn't matter with which Xcode you build your app, the base SDK signifies the lowest system your app is supporting.
You app can and will run on newer systems.
If you want to make an update to your app, you'll need to pay attention to depreciated methods for the newer systems or you will get rejected and won't be able to update in the App Store.
Yes, it will for sure run in higher versions than Deployment Target.
However, is always recommended to run also in newer versions as they are released, to check that every API used is still running fine (specially if they were deprecated).

Xcode 4.4 , IOS 5.1 simulator. Twitter framework issue

Just upgraded to Xcode 4.4 in Mountain Lion and faced with an issue. Built-in Twitter framework doesn't work on IOS Simulator now. Looks like many developers who is upgraded to Xcode 4.4 have the same problem :
https://dev.twitter.com/discussions/4850
So the questions:
Is it an issue of a simulator? Would that twitter-code work in real device?
It's known that from IOS 6 it will be another built-in framework to connect with social media. Can the app with IOS 5 twitter-code be rejected from appstore now?

According to the thread you linked to it's a simulator-only problem. But you should always test your code on an actual iOS device before distributing to the store.

Actually the Twitter framework was available as a built-in framework from iOS 5 onwards. So your iOS 5 compatible implementation isn't going to be rejected in iOS 6 (all things being equal). In fact, if you have a custom, non-'Twitter framework' integration this will still be acceptable - Apple aren't forcing you to use the supplied Twitter framework exclusively.

ios app build for version 5.0.1uploaded to app store can be run on ios 5.1?

I did build app for ios 5.0.1 using xcode 4.2 and uploaded it on apple store. They rejected my app due to crash issue occurs when they install and run on ios 5.1.
Could you please let me know if we build an app for ios 5.0.1 will not be run on ios5.1 iphone device.
What will be the way so I can approved my app at apple store that is build for ios 5.0.1.
But two days ago they approved another app that is build for ios 5.0.1.
Should I query to apple store.
Please reply me thank a lot for time frame given to my ques.
The app can run in iOS 5.1, the thing is that you dont know how that app is going to work on 5.1, so probably you are using something that is allowed in 5.0.1, and in 5.1 is crashing.
Your only option now, is to download the 5.1 on your xCode and check what is going on.
Yes, Apple will approve apps that are built using the 5.0 SDK, though probably not anything earlier. They pretty much always test using the latest version of the OS so you should absolutely test with it before submitting. I'd venture that there's no reason not to develop with the latest too.
The changes between 5.0 and 5.1 are not huge so, chances are, you do have a bug. Apple normally send crash reports when they reject for these reasons.
