I have 2 devices,iphone with 4.3.1 and ipod with 5.0.
The problem is that in my iphone the debugger stop in break points, and in ipod the debugger won't stop on break points.
Any ideas on why that happens?
Have you installed the iOS 5 SDK in your Mac? I think that is what you require.
Also you need to understand that some of the functionalities might still be missing in some of the cases as it is still a BETA version. It might not be a fully functional version yet.
So either you can try using the iOS 5 SDK in your mac or if you have already tried it then I think you should wait for the final iOS 5 full version to work properly.
Also in the below link, they have discussed that some of the functionalities of iOS 5 still doesn't work on iPod. So may be Apple is working on it before the final launch.

iPhone Dev: Xcode debugger does not stop on breakpoints
I think its the same problem like with iTunes. If you use a beta SDK you also need beta iTunes to sync with your device and a beta Xcode. Do you have the beta Xcode? Thats because the official Xcode release don't have an iOS 5 debugger. Open your Organizer and look if your iPod is listed as a supported debugging device.
Do you have iOS5 SDK installed as well? Are you testing with that? If not, the app won't stop at breakpoints. Your XCode version does not have the iOS5 debugger.
Not the solution to your problem, but I faced the same problem and solved it using UIAlertViews & NSLogs. I should also mention that I even installed xcode with iOS 5 SDK beta, even after which the breakpoints won't hit.
It was some issue with the symbols. You can create & display a temporary alert view where you want to put the break-point with its message/title being the value that you want to see, or you can log the value.
To debug a device running iOS 5 you will need to install the beta version of XCode, which contains the iOS 5 SDK. Once you register as an apple developer you can download it from developer.apple.com.

I have an app I want to update of other reasons than change of of iOS, and the work to redesign it for iOS7 is rather big and also not looking good with iOS7.
If I build it with SDK6 using Xcode 4, how do I test it on a device running iOS7. Or do I have to see how it behaves when it is coming up at App Store.
I have also Xcode 5 but with this I can not build it with SDK6, can I?
I can see the result in the iOS6 simulator after a SDK7 build but since the app does not look good with that I do not want to update it that way.
The look is ok on a iOS7 device I know, but how to test it ??
And my devices running iOS7 are not compatible with Xcode 4.
The best way for you is to install Xcode 5 keeping Xcode 4 on your Mac.
For that, copy past your current Xcode 4 in a folder named Xcode4 on your application folder and renamed Xcode.app to Xcode4.app.
After that, update your Xcode to Xcode 5 and create a symbolic link to have the iOS 6 SDK on Xcode 5.
Have a look here, where I explain how to make this symbolic link.
Our iPhone Apps run beautifully up through iOS 6, but certain features do not work on the iOS 7 beta. My fear is that we won't be able to complete our iOS 7 compatibility before iOS 7 is released and our customers will upgrade to iOS 7 and the App will be unusable....resulting in negative reviews, etc...
Does anyone have any suggestions on how to best handle this? Is there a way to set a Maximum SDK that the App supports?
I think if you do this you will get bad reviews anyway, but it may be your only option if you can't revise in time.
You need to take a look at this SO answer and use a condition with a macro like
if(SYSTEM_VERSION_LESS_THAN_OR_EQUAL_TO(#"6.1.3")) {
// work normally
} else {
// fail gracefully
}
to disable any part of your app that is broken post that version number.
I don't think there is a way to restrict users with later versions installing and trying to use your app as there is with users with versions earlier than you require. The reason is probably that while it's OK to use new features and lock out older devices it generally isn't OK to not support new devices indefinitely.
If you run a binary built against the iOS N SDK on iOS N+1, the device substitutes the behaviour of iOS N. Assuming you have an iOS 7 device set up for testing, try downloading anything from the App Store — you should see gradients and wide UISwitches and view controllers acting properly when wantsFullScreen is set to NO and everything else.
So you don't need to handle anything. It's dealt with automatically on the device.
There is not maximum iOS version setting anywhere but it shouldn't necessary.
If you build the app with Xcode 4.6 / iOS 6 SDK, then run it on device w/iOS 7 installed, does it work OK? If so, that's what you should release first (or leave in the app store). If not, you need to fix just those problems that show up and release an update made with Xcode 4.6. Just fix those issue, don't try to restyle and redo everything for iOS7 yet. Most apps built with Xcode 4.6 won't need fixes to run on iOS 7.
When you build with Xcode 5 / iOS 7 SDK, then you'll want to fully use and support iOS 7. But you can't release that build until we get a gm Xcode/SDK anyway. You don't have to go down this path right away if you aren't ready.
Try systemVersion of UIDevice.
Format is 6.1.3 or 7.0.1
Split them with '.' to get major version

iOS project. Base SDK 4.2, deployment target 3.0. A customer is complaining about an issue on iOS 3.1 (he has an old device).
I tried installing Xcode 3.2.3 - the oldest there is for download. It does not offer iOS 3.1 as a test target. Does anyone know how can I enable older versions of iOS on the simulator?
The box also has Xcode 4 (in a different folder). Could it be the case that they're sharing the iOS simulator, and the backwards-incompatible one from Xcode 4 is getting in the way?
There is no substitute for testing on a real device.
I've had a problem with my iPod touch (3rd gen, ios 5.0) crashing in one app. Every day. The dev won't buy, beg, borrow or steal a real iPod touch to test it on so he can fix it. As a user this is extremely frustrating.
EDIT:
The final versions of Xcode with the iPhone SDK, as it was called then, are not available from Apple's download page, but the direct links still work.
The direct links can be found at:
http://chris-fletcher.com/2010/08/28/howto-install-iphone-sdk-2-0-3-1-for-xcode-3-2/
If you use the latest Xcode, you can install device debugging support via the Downloads->Components section, a la: http://cl.ly/3U1V1G3W2p2E1G29342e
http://iphonesdkdev.blogspot.com/2010/04/old-versions-of-iphone-sdk.html
Some of the links are dead though. Apple is removing those old files little by little. Get them while supplies last.
I've been having trouble getting my app to run in this configuration. Has anyone figured out how to do this? Currently, my app doesn't even show up when I try to run on the device.
iOS5 is not supported by iPod Touch 2nd Gen.
No wonder why you're having trouble ;)
You should set Deployment target of your Project to lower firmware version (f.e. 4.3), because iOS 5 is still beta, we are not allowed to run the aps on it.
I'm working on an iphone project for OS3.1.3. I updated my iPhone to iOS4 and now I can't test my project on my iPhone anymore. I tried downgrading but get "device not eligible"
What should I do now?
If I download latest XCode SDK4 will I be able to recreate my app so that it runs both on OS3 and OS4 ? It has no specific os4 features.. it should just run on both and want to test it on real iphone with os4..

First of all, downgrading your phone won't work. at least not with the "official" approach. I think once there is a Jailbreak for iOS4, downgrading your phone should be possible again.
Secondly, Creating an iOS app with XCode SDK4 that runs on your 3.x devices is no problem at all:
Just set the "iPhone OS Deployment Target" Value (Target -> Info -> Build) to "iPhone OS 3.0"
You can build with SDK4 and still target older devices running iOS 3.2 or earlier. How to do this is covered in detail in this other question here.
You can downgrade your phone OS, that's covered in this question over here.
But really the best approach is to update Xcode, compile with SDK4 and support earlier iOS versions as well.
I'm in the same situation.
What is the best ?
1 Upgrade to SDK4 and still target on IOS 3.xx . Will iPhone ios 3.1.3 users be able to download apps built with SDK4 . I don't think so.
2 Downgrade ios4 to ios3 and still work with SDK3.
PS : Someone suggested to get the lastest SDK
You can downgrade iPhones, iPod touches and iPads.
Instructions are here. If for instance you're downgrading a second generation iPod Touch from iOS4 to iOS3.1.3 you'll need the iPod2,1_3.1.3_7E18_Restore.ipsw firmware. A Google search will bring these things up.
Some downgrading references ask you to modify a "hosts" file. I don't think this is necessary, I downgraded from iOS4.2 to iOS3.0 (and to iOS2.0 for fun) without having to do this.
Good luck.
