So as of this writing, the newest version of Xcode is 3.2.5 (though the GM seed of Xcode 4 was just released, still not ready to make that jump). I know Apple graciously decided to stop allowing developers the ability to test their apps in simulator for any OS below 4.* with the past few releases of Xcode.
I know I need at least Xcode 3.2.2 to test legacy OS versions of the iPhone in the simulator (3.*).
I install Xcode 3.2.2 in a folder on the same level of the current 3.2.5 version. After the install, I opened my project that has no issues in the newest version of Xcode.
I go to the project settings and check the Base SDK value. Under that tab there is no option for the iPhone OS. All it allows me are Current Mac OS and Mac OS X 10.5 and 10.6.
I check the current Target Tab and see the same issue. No iPhone OS options.
The PDF that comes with the xcode322_2148_developerdvd.dmg file (downloaded from Apple's repository http://connect.apple.com/) talks about the iPhone and iPad platforms, so I know this is a new enough version.
What is it that I am missing?
Edit:
After looking through what was installed on my system with xcode322_2148_developerdvd.dmg, it appears that Apple left out all of the necessary files for the iPhone portion of Xcode. Guess it's off to Google to find an old, complete version of Xcode. Unless someone here has a good virus free location they are willing to suggest :)

The App Store says I have an update available: XCode 4.6. I'm still running OS X 10.7.5. Will XCode 4.6 run on this OS? I looked at the App Store and Mac Developer site and couldn't find what OS version was required for 4.6.Kindly give me link for Xcode 4.6 running OS 10.7.5. Many thanks.
It will work without any issue. Maybe this page about Xcode Release Notes will be useful for you
When the Mac App Store shows the Application it should run on your system because as on iOS you can decide as developer which OS versions you support. Apple decided to show you the update - so they decided to allow 10.7.5. There are also no information about discontinuing support for 10.7.5 in Xcode 4.6 release notes.
Yes, I'm running 4.6 on 10.7.5 here.
You can go right ahead and download it from the app store.
If you're concerned about it screwing up your existing work, you could rename your existing install. (to ".old" or something)
I cannot find iOS simulator on my mac.
I am using snow leopard, and I recently installed Xcode through the applications DVD. When I go into Developer/Platforms, apparently iOS simulator.platform should be there. But there is only a folder called MacOSX.platforms. There is a few plist files there, and one folder. Inside this folder, called Developer, iOS simulator.app is not there. This folder contains many subfolders, but none contain the application.
Can anyone help?
Thanks!
It is possible the XCode version on the applications DVD does not include the iOS tools. You can download the latest version of XCode here:
http://developer.apple.com/xcode/index.php
At the point that DVD was made, I think you still needed to download Xcode from Apple to get the iOS SDK. Just grab Xcode 4 from the App Store (on Snow Leopard, that'll set you back the princely sum of $5. Upgrade to Lion, it's free). You can also get 3.2.6 for free from Apple's developer site (register for a free developer account), but the bundled iOS SDK is so far out of date, it's worthless.
I wanted to understand the things involved in iPhone app submission in terms of software requirements (not the steps to submit it on Apple iTunes Connect)
When we download the IOS SDK, is XCode included in that ? If yes, what are the latest versions and approx size of them?
When we develop the app and are ready to submit (say as of today), is it necassary to have a particluar (or rather the latest) version of IOS SDK or XCode installed on our system ?
Are there any specific OS X requirements (I mean if Snow Leopard and above is fine) ?
Everything is detailed on the iOS Dev Center (you may need to log in to have the details):
When you download Xcode (or more precisely the "Developer Tools" package), it includes Xcode and a lot of other tools (Instruments, gcc, gdb, llvm, lldb, the iOS Simulator, ...) and also the latest version of the MacOS and iOS SDKs too.
The version and size are mentionned on the download page too (version of Xcode, of the iOS SDK, of the Mac SDK,... everything). Right now (oct. '11) it is Xcode 4.2, iOS 5.0 SDK and OSX 10.7 SDK. Everything come in one package (1.65Go for the latest version as of today) except the documentation, which is downloaded automatically by Xcode itself (unless disabled) in the background.
For the requirements, it is also described in the iOS Dev Center: Xcode4 is available for both Snow Leopard (on the iOS Dev Center) and Lion (via the Mac AppStore) right now.
When you submit your app, you normally should always submit it using the latest SDK (1). [EDIT after #progrmr comment] except of course for beta versions of the SDK. Alsways submit with the latest "release"/public SDK version]
Note that using the latest SDK does not mean that you need to stop supporting and testing for previous iOS versions. You can use the iOS 5.0 SDK and publish an app that is running on iOS4.x for example (and of course it is better if it still works on iOS5.x too); ascendant compatibility is generally guaranteed, unless specified for specific methods (see the "SDK Compatibility Programming Guide" in the Apple Doc for more info).
(1) It is generally accepted if you submit with the SDK version just before the latest if it is not too old, Apple let you some time to migrate, but this is generally just a transition phase. It is advised and a good practice to migrate to the latest SDK when it is available -- or not too late after that.
XCode 4.2 is about 1.8gb, and that doesn't include documentation - when you first load XCode it tries to download something like 2-2.5gb of docs in the background. You have to both cancel the download and the auto update check to avoid that (but auto updating docs is cool).
I don't recall any requirement to use the latest and greatest, you can still download XCode 3 with iOS SDK 4.3 from the archives. But I can't say for sure, I always run the latest (I find upgrading to new XCode releases is generally a good idea).
XCode is available for Snow Leopard once you buy the $99/yr iOS developer subscription, the mac app store has it but only for Lion. The advantage of the MAS version is you can play with the SDK and making basic apps for free, just not run code on your iOS device.
I'd like to ensure some backward compatibility for my apps by compiling them using the older SDKs to test for newer classes and methods. However, Xcode is only available with SDKs for the latest iOS versions.
I've downloaded and installed the iOS 3.1.3 SDK (using the method described here) and that works fine. My code is full (not so full :-) ) of __IPHONE_OS_VERSION_MAX_ALLOWED, __IPHONE_OS_VERSION_MIN_REQUIRED and such respondsToSelector.
This works right now for the iOS 3.1.3 SDK, but what if in the future I wanted to repeat this process with the 4.0 SDK? Is there a general process for installing older SDK versions in the latest Xcode?
You can't install old 3.1 SDKs on Xcode 4. You can set the Deployment target lower to allow testing on devices running older OS versions than your current SDK installation. The only current way to completely ensure backward compatibility, while running more recent versions of Xcode, is to keep a device that runs iOS 3.x, and test on that device. (...because it is claimed that the old Simulators/tools sometimes actually allows APIs that won't run on an actual device with an OS of the same version).
Other methods include installing the different versions of iOS developer tools in a separate Developer_XYZ directories, and or keeping around a bootable HD with the older iOS developer tool installation (say Snow Leopard with Xcode 3.x, since Lion might only support running Xcode 4.x).
For whatever reason (I had to do it to debug an Apple bug), if you still need to install an older SDK to your existing Xcode, follow these steps :
Install the older Xcode package
Copy the older Xcode SDK to the new Xcode
Example
(/old/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk to /new/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs)
Restart your 'new' Xcode
You will see the old SDK in the build setting option (base sdk)
I am trying to provision my app to run on my iPad for testing. I have everything set up properly, but in the organizer, Xcode displays this message:
The version of iPhone OS on “iPad” does not match any of the versions of iPhone OS
supported for development with this installation of the iPhone SDK. Please restore the
device to a version of the OS listed below, or update to the latest version of the iPhone SDK;
and then it gives me a list of available iOS versions (3.2.2 is not one of them.)
I have restored it back to the factory settings and done everything I could find online and searched around. Does anyone know what could be causing this problem? It won't let me compile it to the device as a result. Thanks!
Which version of the iOS SDK are you using? Make sure you're using the most recent.
