This tutorial describes the installation and usage of Apple’s Xcode set of utilities for macOS developers.

Xcode is Apple’s free app for developing custom programs for all Apple devices (macOS, iPhone, iPad, Apple Watch). Increasingly, Machine Learning developers are using the Swift language.

Since the Apple Store only handles individual .app files, other mechanisms are needed to install additional programs needed as a pre-requisite by Homebrew, Python, and other development programs.

BTW Xcode only works on macOS. There is no Windows PC version.

About Xcode

PROTIP: Skip Apple’s websites and App. Click here for install instructions (below).

Otherwise, read on for a run-around.

1. Use an internet browser to view Apple’s Xcode marketing page at:

   Xcode “includes everything you need to create amazing apps for all Apple platforms. Now Xcode and Instruments look great in the new Dark Mode on macOS Mojave. The source code editor lets you transform or refactor code more easily, see source control changes alongside the related line, and quickly get details on upstream code differences. You can build your own instrument with custom visualization and data analysis. Swift compiles software more quickly, helps you deliver faster apps, and generates even smaller binaries. Test suites complete many times faster, working with a team is simpler and more secure, and much more.”.

   BTW the “Apple platforms” include MacOS, iPhone, iPad, Apple TV, and Apple Watch.

Xcode does not come with macOS because of its large size and because many users of macOS don’t need it to do software development.

Developers who use another IDE (such as Visual Studio, Eclipse, etc.) would only need to install Xcode’s command line utilities for the GCC compiler Python needs to build code.

PROTIP: Newer versions of Xcode installer also installs a Git client.

Overlapping installers

Imagine a Venn diagram of overlapping circles:

1. The Xcode IDE, which can be installed on a Terminal command line interface (CLI) or

2. downloaded as a package from the App Store.

Xcode Mac 10.13

Either way, Xcode contains:

1. Command Line Utilities which can be installed separately on a Terminal command line session.
   

PROTIP: Xcode IDE cannot be installed if Command Utilities has already been installed.

However, you can switch:

So choose which one you want installed.

What Has Been Installed?

1. In a Terminal window, find out what has been installed:

   That’s the same command as:

   If the Xcode-select command is not found, choose to eitherinstall Command Line Tools or install the full Xcode IDE.

   You have Command Line Tools installed and not the full Xcode if you see the path where CommandLineTools are installed:

   If all you need is Command Line Tools, you’re good to go.

   Alternately, if the full Xcode was installed, you would instead see:

2. Get a list of its folders if Xcode IDE was installed:

   The response would be:

   Delete first

3. PROTIP: If you want the full Xcode IDE when you have the Command Line Tools installed, first uninstall Command Line Tools, then install the full Xcode IDE.

   More version information

   Xcode Version

4. From within a Terminal, type:

   If Command Line Tools was installed, you would see:

   If Xcode is installed, you would get a version code that should match up with the Build Number on the Apple web page:

5. For a more precise version number and other info (macOS Mavericks version and up):

   A sample response, at time of writing:

   The previous command was constructed based on a search of tools package names:

   The response:

6. Get the version of GCC installed:

   If Xcode was installed, you would see (at time of writing):

   Previously, it was instead:

   If Command Line Utilities is installed, you would see (at time of writing):

7. Identify the path where the make utility Java uses:

   a. If Xcode is installed, the response is:

   b. If Command Line Utilities is installed, the response is:

   c. If no Xcode is installed:

   Swift version

8. Get the version of the Swift program used to develop iOS mobile apps:

   Sample response at time of this writing:

   If jamf installed Xcode, you’ll also see:

   The above appears regardless of whether Command Line Utilities or Xcode is installed.

   From here, uninstall and install Command Line Tools or install the full Xcode IDE.

   UnInstall Command Line Tools

   PROTIP: This is also how you upgrade Command Line Tools.

9. Go to the parent folder where Command Line Tools is installed:

10. Get a list of its folders:

    If Command Line Tools were installed, the response would be :

11. Remove all files in that folder, which requires a password for elevated permissions to get all the files:

    The response is a lot of files removed (to the Trash).

    Now you can choose to eitherinstall Command Line Tools or install the full Xcode IDE.

    Install Command Line Utilities only

    See https://developer.apple.com/library/archive/technotes/tn2339/_index.html and http://osxdaily.com/2014/02/12/install-command-line-tools-mac-os-x

With Xcode you can work inside one window, split windows, and even compare options side by side. Source and project code can be shared across both platforms.

MacOS app developer made simple and easy

Design great apps on either Mac, iPad, or iPhone using Xcode.

MacOS or iOS developers need look no further than the Xcode developer tool to design great apps.

Xcode featuresSwift UI, which offers up its own syntax. Easy to read and write, Swift UI will help keep your apps smaller and download faster by using less code.

Updated functionality now lets you code, test and debug all inside one window. Debugging is done via the Xcode IDE. This added plus can identify errors in syntax and logic, and often fix the code for you.

Newly introduced dark mode is built into Xcode. Interface builder allows you to switch between light and dark modes, or even view them side by side.

The drag and drop function helps you to make changes to visual UI elements, quickly and easily. For developers who prefer multiple editing panes, Xcode provides you with total control of your work area. You can view your design changes instantly in another window.

Use the devices window to simulate other environments. If your users have slow networks or run in extreme heat, you can test those conditions out before releasing your app. For ease of use, source and project code can be shared by Mac and iPad, allowing you to convert existing iPad apps into Mac apps. The changes will take effect across both platforms.

Where can you run this program?

You can run Xcode on OS X 10.8 Mountain Lion or iOS 7 and above.

Is there a better alternative?

With its solid functionality, multiple panes, and shared source code, there is no need to look at any alternatives when choosing an app development tool.
