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.

I was developing iPhone/iPad apps using XCode 4.2. With the recent update, I upgraded my XCode to 4.5 with iOs6. And I developed an iPhone app with this. But the issue when I run the app in iPhone 3GS with iOs 4.3, it crashes some times. I couldn't find any specific or common reason for this crashes. It happens randomly, not when doing a specific action. But it happens very rarely in iPhone with iOs 5 and iOs 6. I tried to track the issue using Instruments, but still I couldn't find any reason. Some memory leaks are there, but it wasn't the issue.
So, I have some guesses, may be it is happening due to the device is 3GS? Or because, some codes that come with iOs 6 not supporting in iPhone 3GS or iOs 4.3. In the Xcode it is not showing any warning.
So, I am not sure, is there any possibilities for my guess??
Also, I would like to know, now we have iOs 6, so when we develop new app, should we still support iOs < 5? Or can we specify it needs iOs 5 or above as requirement?
Please give me some suggestions.
Regarding your first question - "App crashing randomly". You have mentioned that your app crashes on all the iOS versions - rarely on 5 & 6 but frequently on 4.3. If this is the case, then as per my experience, this issue is mainly related to "Low Memory". To verify this, debug your app on device and check your Debugger giving you "Low Memory Warning". This is the way you will find your issue.
Now regarding your second question - "which iOS to support". Answer to this would be iOS 5.0 and above - YES. Not all the iPhone/ iPad users have updated their devices to iOS 6. Also some of the users can't because of device issues. So you must provide support for iOS 5.0 at least. As per the latest stats iOS device users are hardly using iOS 4.x but iOS 5.x users are plenty enough. A lot of apps in App Store don't provide support for below iOS 5.0. So go for iOS 5.0 and above. Rest it depends on your requirements like if the app is pretty simple enough then providing support for below iOS 5.0 is not a headache.
I want upload app to app store for review but it seems like I need also iPhone 5 screenshots but I don't have app prepared for iPhone 5. Please, how can I deploy app only for iphone 3gs,4,4s?
I find something in Targets/Build Settings/Architectures Standard armv7 and Base SDK is Latest iOS 6.0. Is that what I have to change?
Just for absolute clarity, Apple released an announcement on March 21st 2013 stating that starting May 1st 2013 new apps and app updates MUST be built for iOS devices with Retina display and iPhone apps must also support the 4-inch display on iPhone 5.
You can view the announcement here.
The best solution is to just properly prepare your app for the iPhone 5's display. And no. Changing the base SDK will not help here.
You can't, only apps submitted before iPhone5-release can run in "iPhone 4 mode" on the new iPhone. All updates to apps and newly submitted apps must support the new 4 inch screen.
You cannot exclude the iPhone5 in the target settings and if there were a way to do that, there is no way Apple would approve it. You can remove support for old devices, but never for new ones.
After all, Apple wants as many apps as possible to adapt the new format as soon as possible, and this is what you have to do... don't worry - if you are fairly used to developing to iOS you can do it in just a few hours...
Apple has stated that theY will still (currently) be accepting apps without specific iOS 6 and iPhone 5 support when developed with an Xcode version prior to 4.5, and thus with an SDK 5.1 or earlier. 568h support is specifically not allowed in apps built that way.
Apps built that way will run in letterbox on a 5, or the similar 1X/2X compatibility boxes that the iPad uses for legacy iPhone only apps.
I submitted an app following the release of the iPhone 5 with the latest version of XCode that runs letterboxed on the iPhone 5. Just remove armv7s from your supported architectures.
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.
What are the iOS version do i need to consider when developing iPhone application?
Based on my research, iOS 3.x, 4.x and 5.x have been considers as available iOS version. But when I consider with devices there lack devices which is running iOS 3.x.
Can someone help me with finding trusted sources where I can find these details i.e source from Apple or something?
From Apple themselves, 93% of users are on iOS 6:
https://developer.apple.com/devcenter/ios/checklist/
Unless you need to support the iPad 1 or the very old iPhone 3G (not 3GS), go for iOS 6! :)
You can find the percentage of users in this post:
Most current iOS version distribution percentage?
And then decide by yourself which version you should develope to
I just finished my first app developed in XCode 3.2.1 in iPhone Device 3.1.2. I know that there is iPhone 4 now, does that mean that I have to upgrade to iOS 4 before I submit my app to App Store? Or do I keep two versions of my app, one is the 3.1.2 version and the other iOS 4 to cover all iphone market (old and the latest one)?
You should download and install the iOS 4.2 SDK.
You should then compile and link against the iOS 4.2 SDK.
It is likely that Apple will end support for 3.x in the near future.
Also, sort out your acceptance rate problem...
