Description

Xcode includes everything developers need to create great applications for Mac, iPhone, iPad, Apple TV, and Apple Watch. Xcode provides developers a unified workflow for user interface design, coding, testing, and debugging. The Xcode IDE combined with the Swift programming language make developing apps easy and fun.

Xcode includes the Xcode IDE, Swift and C/C++/Objective-C compilers, Instruments analysis tool, simulators, the latest SDKs, and hundreds of powerful features:

Innovative tools help you create great apps
• Swift is an intuitive programming language that is safe, fast, and modern
• SwiftUI is a revolutionary framework to create user interfaces with a declarative Swift syntax
• Playgrounds are a fun way to experiment and interact with Swift code
• View debugging shows a 3D stack of all your app’s UI view layers at runtime
• Split editors in virtually unlimited ways, show previews, or choose an assistant to see related content
• Live issues display errors as you type, and Fix-its improve your code with just a click
• Source control navigator and service integrations help you manage code across a team

SwiftUI and Interface Builder make it easy to design your interface
• SwiftUI uses declarative Swift code that clearly describes your interface
• Design canvas graphically builds UI views using the library of controls and modifyers
• Preview SwiftUI code or UIKit interfaces in different screen sizes, orientations, and font sizes
• SwiftUI code is always in perfect sync with the graphical design canvas and previews
• Animations are built using simple commands that describe the action you want to see

Professional editor and debugger keep your code front and center
• Refactoring makes it easy to modify the structure of Swift, Objective-C, C, and C++ code
• Open Quickly instantly opens any file within your project
• Data tips and Quick Look can inspect a variable by hovering your mouse over code while debugging

Instruments for performance analysis
• Compare CPU, disk, memory, and GPU performance as graphical tracks over time
• Identify performance bottlenecks, then dive deep into the code to uncover the cause
• Analyze your app directly, or sample the entire system with very little overhead
• Create custom instruments with unique visualizations to analyze your own code and frameworks

To test or run applications on an iPhone, iPad, Apple TV, or Apple Watch all you need is a free Apple ID. To submit your apps to the App Store you must be a member of the Apple Developer Program. Some features may require Internet access.

Xcode install (on MacOS)

Xcode IDE contain Command-Line utilities. But separate Command-Line installer cause errors for use by Homebrew, Python, and other development tools

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

Otherwise, read on for a run-around.

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:

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

Either way, Xcode contains:

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?

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 either install 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:

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

The response would be:

Delete first

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

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:

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:

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):

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

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.

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

Get a list of its folders:

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

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 either install Command Line Tools or install the full Xcode IDE.

Install Command Line Utilities only

To install the whole Xcode IDE:

You should see this pop up:

Manually click “Install”, “Agree”, then “Install” to the “Updates Available” pop-up.

NOTE: The xGB download takes 13 minutes on a 10mbps line.

When you see “The software was installed.”, click “Done” to dismiss the pop-up.

Xcode IDE install from Terminal

Make sure you have at least 13GB free on your hard-drive before attempting installation.

1. Click the Apple icon to select “About this Mac”.
2. Click “Storage” tab.

In an internet browser, get to the “Mac App Store Preview” for Xcode at
https://apps.apple.com/us/app/Xcode/id497799835?mt=12

Click View in Mac App Store, then “Open App Store.app” in the pop-up.

Provide your Apple ID and password. Get one if you don’t already have one.

PROTIP: DO NOT install a beta version of Xcode.

The blue “OPEN” icon appears at the upper-right when the app is installed. But don’t click it because we are done.

In Finder, look for Xcode.app in the /Applications folder.

Alternately, on the Touchpad pinch 4 fingers together to click the App Store. Type enough of “Xcode” to filter out others.

To view the version, cursor to the top of the screen and click the program name next to the Apple icon to select “About Xcode”:

A) Initial install from Terminal CLI

Open a Terminal.app console window at any directory to install -all the latest Xcode from Apple:

The response on Catalina version of macOS:

Click the Apple icon at the upper-right corner and select “Shut Down…”.

After starting again

Set Apple’s licensing agreement bit:

Manually agree to the terms.

Get the version number of the new version.

B) Initial IDE install using web App Store

Sign in to Apple Developer with your email address then click the arrow icon. Enter your password, then click the arrow icon.

Below is the “Software Update” approach:

You’ll need to establish an Apple ID if you haven’t already.

Click the cloud icon Download and provide your Apple ID.

Go through Apple’s location verification if prompted.

Confirm your account.

Click “Allow” to the pop-up “Do you want to download?”.

Xcode size

CAUTION: Make sure that your machine has enough free space available.

These are massive files that may take a while to download if you don’t have a fast internet connection.

NOTE: Each version of Xcode is related to a specific version of the Apple OS Mac operating system.

File	Date	Download	Unpacked
Xcode_12.1	2020-10-01	10.5 GB	11.5 GB
Xcode_11.5	2020-06-01	7.5 GB	? GB
Xcode_10.2.1	2019-04-17	? GB	6.1 GB
Xcode_9.0	2017-09-19	. ? GB	? GB
Xcode_8.2.1 8C1002	2016-12-19	? GB	? GB
Xcode_8_beta_2.xip	2016-07-05	5.9 GB	12.32 GB
Xcode_7.31	2016-05-03	3.8 GB	?
Xcode_4.1	2014-	2.9 GB	?
Xcode_3.2.4	2014-	2.? GB	?

Switch to Finder Downloads folder to watch progress on the file name ending with “Download”. The one with a clock icon which signifies downloading.

Return to the versions instructions above to view the updated version.

Delete the installer after you’re done, to reclaim disk space.

Xcode IDE Upgrade

Over time, Apple updates Xcode and its command line utilities.

Click the Apple icon, then click System Preferences. Here is an example notification:

Search for “Software Updates” or click the icon.

Click “Update Now” if that appears. (but first do a backup.)

Click “Agree” to the EULA.

When done, view the version numbers installed.

Xcode FileMerge tool

Xcode graphically compares files and directories.

Open Xcode. This takes a few seconds.

Right-click on Xcode icon. Select “Open Developer Tool”. Select “FileMerge”.
