Setting up your Mac for iOS app development

Students will need:

  1. Mac computer running OS X 10.10.5 or later (required to download Xcode 7), with at least 8 GB of RAM.

If you are upgrading your operating system, remember to backup existing iOS projects, software keys, etc -- ideally on an external hard drive.
If you have specialty software (video editing software, etc), please check with the user and support communities to verify the compatible versions of OS X before upgrading.

  1. Xcode -- the integrated development environment (IDE) from Apple for making software for iOS and OS X
  • First check to see if you already have Xcode installed on your Mac (look in your Applications folder):
    • if you already have Xcode, open the software to see which version number you have
    • if you don't, follow this link: https://developer.apple.com/xcode/download/
      • Here you will be asked to create an Apple Developer account.
        • If you already have an Apple ID, you can sign in with this.
        • You only need the free version.
        • However, if you want to release your app in the app store, you will have to enroll in the iOS Developer Program. This costs $99 a year.
      • If you have slow internet downloading Xcode could take 10 hours; however, if not, it should take 10 minutes. If you find yourself with a 10hr download time go to your local Apple store (free wifi and no password required).
  1. git -- a version control system for software development
  • First check to see if you already have git installed on your Mac:

    • open the Terminal program (look in Applications > Utilities)

    • type:

      git --version

    • if you have git already installed on your Mac, then you will see a result like this:

      git version 2.6.2

    • for any other result, Ctrl + C to escape back to "the command line" (more about the command line)

  • if you need to install git on your Mac, follow this link: http://git-scm.com/downloads
    • the easiest way to check if the installation worked:

      • open a *new* Terminal window, and

      • again type:

        git --version

Optional (more detail coming later)

  1. GitHub for Macs -- if you are new to git/GitHub install this GUI tool after installing git as described above
  1. Homebrew
  2. CocoaPods

#Installation Checkout

Please email us the following:

  • screenshot of your OS X version

  • screenshot of your Xcode version

  • screenshot(s) of the results of the following commands (run from the Terminal):

    echo $PATH

    which git

    git --version

    > if any of the following shell initialization files (.profile, .bash_profile, .bashrc) are too big to easily take a screenshot of the contents displayed by the 'cat' command, then just attach them to the email.

    cd ~

    cat .profile

    cat .bash_profile

    cat .bashrc

Some of these commands may return no result, meaning these files are not on your machine, which is not necessarily a problem, but it's good for us to know if you do.

Now make your first iOS app or return to the main page.
