So, you'll need a MacBook computer or iMac to use it. The tool was called Project Builder but renamed to Xcode somewhere around the time Mac OS X 10.3 or 10.4 was introduced. It has compilers, graphics debuggers, text editors, an integrated build system, to mention a few. It comprises all the tools required to develop fully functional applications. It is called IDE because it packs in one place all the tools required to develop fully functional applications. Xcode is an Apple's Integrated Development Environment (IDE) that programmers can use to develop apps for iOS and macOS devices. Part 3: Downgrade Xcode by Uninstall and Reinstallīefore getting to the guide on Xcode downgrade, let's see what exactly Xcode is. If you choose not to delete these items on the first launch of Xcode 4.3, you can remove the /Developer folder and the Install Xcode application by dragging them to the Trash at any time.Part 2: Downgrade Xcode by Downloading Older Version of Xcode Some operations may require an administrator password to enable them if you switch from one version of Xcode to another.įigure 4 Option to remove older versions of Xcode These actions are optional, Xcode 4.3 can co-exist with older installations of Xcode on the same Mac. Note: The first time you run Xcode 4.3, you are prompted with a dialog to delete the Install Xcode application from the Applications directory if one is resident, and to remove any older installation of Xcode (Figure 4). As a result, the Install Xcode application and the uninstall-devtools command line script are also no longer needed. The simplification afforded by repackaging Xcode 4.3 as a single app bundle eliminates the need for the /Developer directory containing prior versions of Xcode. This is reiterated in New Features in Xcode 4.3 (emphasis mine). You can delete the older version of Xcode by dragging the Developer folder to the trash. Previous versions of Xcode placed the tools and frameworks in the Developer folder. Xcode 4.3 and later is packaged on the Mac App Store as a single application and installs in your Applications folder as Xcode.app. To run the latest version of Xcode, make sure you are launching Xcode.app from the Applications folder. I've installed the latest version of Xcode from the Mac App Store, but a previous version of Xcode (4.2.1 or earlier) keeps launching. The Xcode section of the Apple Developer Support Center actually tells you to do this (emphasis mine). It looks like you just have to remove the /Developer folder (especially if you have already installed version 4.3 or later of Xcode). As with any such commands, precision and compatibility are critical. Pleae super-double check that this documentation either exists with your installation or is the same as your installation before you act. You should use the one installed with these Xcode developer tools. NOTE: The uninstaller that ships with previous versions of the Xcode developer tools will not clean everything off of your system properly. $ sudo /Library/uninstall-devtools -mode=xcodedir $ sudo /Library/uninstall-devtools -mode=unixdevįinally, to just uninstall the directory you can simply drag it to the trash, or from a Terminal window type: To just remove the UNIX development support on the boot volume, but leave the directory and supporting files untouched, from a Terminal window type: $ sudo /Library/uninstall-devtools - mode=systemsupport To remove the underlying developer content on the boot volume, but leave the directory and supporting files untouched, from a Terminal window type: $ sudo /Library/uninstall-devtools -mode=all To uninstall Xcode developer tools on the boot volume along with the directory, from a Terminal window type: This is covered in the documentation that comes with the Developer Tools install: Based on your OP, I am assuming you are running pre-Lion Xcode.
