How do you update Xcode on OSX to the latest version?

问题

What is the easiest way to update Xcode on OSX?

I see this in the terminal:

$ brew install xxxxxxx
Warning: Your Xcode (4.3.3) is outdated
Please install Xcode 4.6.

But when I go to open up Xcode > Preferences > Downloads, it says there are no updates?

回答1:

1. Open up App Store

   

2. Look in the top right for the updates section

   

3. Find Xcode & click Update

   

回答2:

softwareupdate --list see the list of outdated software.

softwareupdate --install --all update all outdated software.

softwareupdate --install <product name> update the software you named.

回答3:

Sometime I don't see the Xcode update in Updates tab in AppStore
So I search Xcode in AppStore

Then click update and it update

回答4:

If attempting to download via the App Store leaves you with a little grey spinner and nothing actually happening, then you can go to :

https://developer.apple.com/download/more/

log in with your Apple Developer ID, and the latest Xcode should be available as a .zip download.

In my case (Xcode 6.1, iOS 8.2) I did not see the update in AppStore. I found Xcode 6.2 for download and pressed "Install". Then, it installed and asked for the update (more than 2 Gb). Xcode 6.2 works correctly with iOS 8.2 and iOS 8.1.2

Hopefully this tip will help somebody else...

If you want the latest Beta, it will not be in the AppStore. Instead you have to login to https://developer.apple.com and download from there.

Another best way to update and upgrade OSX development tools using command line is as follows:

Open terminal on OSX and type below commands. Try 'sudo' as prefix if you don't have admin privileges.

brew update

and for upgrading outdated tools and libraries use below command

brew upgrade

These will update all packages like node, rethinkDB and much more.

Also, softwareupdate --install --all this command also work best.

Important: Remove all outdated packages and free some space using the simple command.

brew cleanup

I ran into this bugger too.

I was running an older version of Xcode (not compatible with ios 9.2) so I needed to update.

I spent hours on this and was constantly getting spinning wheel of death in the app store. Nothing worked. I tried CLI softwareupdate, updating OSX, everything.

I ultimately had to download AppZapper, then nuked XCode.

I went into the app store to download and it still didn't work. Then I rebooted.

And from here I could finally upgrade to a fresh version of xcode.

WARNING: AppZapper can delete all your data around Xcode as well, so be prepared to start from scratch on your profiles, keys, etc. Also per the other notes here, of course be ready for a 3-5 hour long downloading expedition...

I used the Command_Line_Tools_OS_X_10.XX_for_Xcode_7.2.dmg and therefore had to download the latest version from here.

回答10:

You DO NOT need to upgrade Xcode.

Just open the file /usr/local/Homebrew/Library/Homebrew/extend/os/mac/diagnostic.rb ,

then remove this line check_xcode_minimum_version in the following function.

def fatal_build_from_source_checks
    %w[
      check_xcode_license_approved
      check_xcode_minimum_version //<-- this one
      check_clt_minimum_version
      check_if_xcode_needs_clt_installed
    ].freeze
    end

Then brew install should works fine.
