I am developing an app with Xcode 4.0.2 and iOS 4.3. Now I would like to upgrade to Xcode 4.2 and iOS 5 so that I could make my app ready when iOS 5 releases in October.
I am told by Apple's website that I should not submit apps that are built by Xcode 4.2 and should do it with the older Xcode 4.0.2, since the Xcode 4.2 and iOS 5 thing is still in beta.
But in the following few weeks I still need to have newer versions of my app submitted to App Store. So my question is,
If I upgrade my Xcode to 4.2, is it possible for me to switch back to Xcode 4.0.2?
If yes, how?
Thanks in advance!
You can simply install two versions of Xcode at the same time. During the installation it will let you choose the destination folder; you can pick another folder. For example, I use /Developer/Xcode (4.2). (However, if you did install 4.2 over 4.0.2, I don't think you would have a problem if you just ran the 4.0.2 installer again to downgrade.)

Installation
The Xcode installer will create the folder /Developer on the root of your boot partition, and place the Xcode developer tools and SDKs in this folder. If you have a previous version of Xcode you would like to preserve, you can copy the existing installation from /Developer to another folder to prevent having it updated automatically by the installer.
I would be cautious of this note (possible problems from incompatibility of tools???)
NOTE: The Xcode installer also installs system components and UNIX command line tools in a shared location on your Mac. Only one version of these components can exist on a computer at a time, and the last installed version replaces any previously installed set.
I always make sure I have a bootable drive with a decent working copy of xcode ready for releases in case I need to push a quick fix.
You can install 2 XCode in different folders.
Then you can switch back and forth.
Can I have multiple Xcode versions installed?

So I saw this post: http://mobiledevelopertips.com/xcode/download-and-install-older-versions-of-xcode-xcode-previous-releases.html
(new location: at iosdevelopertips.com)
about downloading older versions of Xcode. Up to now, I have always just downloaded the newest version of Xcode from the App Store and let it do its thing. Recently on one computer that has Xcode 4.5 installed on it, I noticed that if I create a new project, I only get the iOS 6.0 simulators, not the 5.0 or 5.1.
My first question is, do I need older versions of Xcode to build apps for older OS (e.g. iOS 4, iOS 5.0, 5.1, etc)?
If so, what's the best way of installing these older versions of Xcode. I see that they have the command line tools to download as well. I'm not sure how all that stuff works.
What's the best way to update to the latest Xcode but keeping the old Xcode around? On a different machine that had Xcode 4.4.1 installed, I thought I could download Xcode 4.5 from the ADC website and install it. I downloaded it, double-clicked on the .dmg, then double-clicked on the Xcode file. This then installed Xcode 4.5 without asking me where I wanted it installed so I could keep the older version of Xcode (assuming that I need it as stated in my 1st question).
Thanks!
To answer your questions:
1) Yes. I renname Xcode to add the version number (i.e. Xcode_441.app)
2) I keep an archive of all versions of Xcode that I have downloaded so they are available after Apple pulls them from their download site.
3) Renaming them works for me, and I usually grab the direct download, when available, instead of getting it from the MAS. Try renaming Xcode before doing an install.
You are welcome.
It's possible to have multiple XCode installations by customizing the install path. Also note that the new 4.x install model is app bundles under Applications which are self contained so it's possible to just rename the old before installing the new XCode. You can also download the newest (4.5) from the developer site.
You can also add the old simulators by going to XCode preferences in 4.5.
Look under XCode, preferences, downloads. XCode 4.5 offers the 5.0 and 5.1 simulators for download. The same place that you download the command line tools.
For example, I added the 5.0 Simulator to my XCode 4.5 installation to go along with the 6.0 Simulator:
I noticed that if I create a new project, I only get the iOS 6.0 simulators, not the 5.0 or 5.1.
Choose your project target and in Summary tab, set the lowest Deployment Target for your app (I think the default value is 6.0 in Xcode 4.5).
My first question is, do I need older versions of Xcode to build apps for older OS (e.g. iOS 4, iOS 5.0, 5.1, etc)?
If you've updated from old version of Xcode, you can use the old SDK & simulator in new version.
If so, what's the best way of installing these older versions of Xcode. I see that they have the command line tools to download as well. I'm not sure how all that stuff works.
Actually, different versions of Xcode can stay happily with each other. It is a App Bundle right now.
third question
Just drag the new version of Xcode to Application folder. That's done. :)

Uninstall Xcode 4 and use Xcode 3
I am Abbas. I am new to iPhone Programming.
Tomorrow I have updated my xcode to 4.2 from version 3.2, But i am having problem to use it.
I have to uninstall xcode 4.2 from my mac and install xcode 3.2.
I have setup of both the version, but i do not know the procedure to uninstall xcode.
So.
Please Help me.
Thanks.
Open Terminal and use this command:
sudo /Developer/Library/uninstall-devtools –mode=all
if your XCode is in different directory, use that path. After that you can delete the rest of the /Developer directory.
From Xcode 4.3, the xcode is available on mac app store. If you download it from mac app store, it will be installed in this folder: /Applications/Xcode.app.
If xcode version is below 4.3, the installation directory can be changed in the installation wizard. The default installation directory is in /Developer folder. And if you choose the default folder when install xcode4.2 and the xcode3.2 is also in that folder. The xcode3.2 will be over written and removed.
If you want to keep both xcode 4.2 and 3.2, you can install them in different folder. For example, I installed xcode 3.2 in folder /xcode3 and xcode 4.2 in folder /xcode4, and I also have a xcode4.3 in folder /Applications/Xcode.app.
The problem is the newest ios simulator is only available in the lastest xcode. For example, the ios5.1 simulator is only available in xcode4.3 . So, maybe we should spend time to get familiar with the lastest xcode.
Hope it will help.
I installed Lion, then XCode 4.2 from the app store.
As I understand, the iOs SDK should be install with this release.
My problem is, I only get the MacOs templates, no iOs templates.
What am I doing wrong? (It's taking Apple a few weeks now to process my company enrollment and I need to start coding so long).
While installing you need to check that you want to install iOS 5.X SDK, it doesn't install automatically. Re-run the "Install Xcode" application which AppStore downloaded and check to install iOS SDK
Be sure that /Developer/Platforms/iPhoneOS.platform exists. If so, then iOS files were installed.
The iOS templates are contained in /Developer/Platforms/iPhoneOS.platform/Developer/Library/XCode/Templates
If they are there, but are not showing up in XCode, you can try repairing disk permissions with /Applications/Utilities/"Disk Utility".
Otherwise, you may have to rename the /Developer folder and re-install.
I am currently working with Xcode 3.1.3 , i wanted to upgrade it to new version of Xcode 4.0.My question is will i be able to run my older applications which were built on Xcode 3.1.3 on the new version of Xcode.
Thanks in advance
Yes you will be able to do so. However PPC support and 10.4 support is dropped on the mac. If you want to play safe, you can install Xcode 4 in a separate location leaving your Xcode 3.1.3 untouched, so you can switch between these two.
The project format of Xcode 3.2 and Xcode 4 is the same.
One option is to install Xcode 4 into another directory. I just installed the latest version yesterday and it offers you this option. Here is a link here about this also. There is also a StackOverflow question here. If everything works as you expect you can delete Xcode 3.1.3. If not, you still have your current version around.
I installed the new GM iPhone sdk. When I try to compile against iOS 3.0, it claims that libraries are
missing. What now? I think that I have the install DMG somewhere for 3.2.2, if that helps.
Always use the newest SDK available. There is little to be gained (and a lot you give up) by building against older SDKs. It limits both what APIs you can call and also prevents your code from taking advantage of the OS features on newer devices.
If you need to deploy on older OS versions, just set the Deployment Target to the earliest version you need to run on. You don't need its SDK.
Do the following
sudo /Developer/Library/uninstall-devtools –mode=all
(This will uninstall the current XCode installation)
Then install first old XCode (3.2 final) in default folder (/Developer)
Then install the new XCode (3.2.3 GM) in other folder (/DeveloperBeta)
This way you will have both. And can launch xcode from either /Developer/Applications/Xcode.app or /DeveloperBeta/Applications/Xcode.app
3.2.3 last beta did remove all other SDK's cause to many people tried to publish Apps developed with the beta SDK, which would not be accepted by Apple. With GM it will be the same
