With an all-new design that looks great on macOS Big Sur, Xcode 12 has customizable font sizes for the navigator, streamlined code completion, and new document tabs. Xcode 12 builds Universal apps by default to support Mac with Apple Silicon, often without changing a single line of code.
Designed for macOS Big Sur.
Compatibility: Windows 10/8.1/8/7/Vista and Mac OS X 10.14.4. 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.
- To be perfectly clear, Apple’s Xcode is a fabulous development system for C, C, Objective-C and even Fortran 77. You can build native OS X and iOS apps. But many researchers and scientists.
- This document outlines the process of installing Xcode on Mac OS, which provides a compiler for C source code. The first illustrates how to write, compile and execute C programs in the Mac OS Terminal window using the command prompt tools the second illustrates how to use the graphical Xcode environment to build and run C programs.
Xcode 12 looks great on macOS Big Sur, with a navigator sidebar that goes to the top of the window and clear new toolbar buttons. The navigator defaults to a larger font that’s easier to read, while giving you multiple size choices. New document tabs make it easy to create a working set of files within your workspace.
Document tabs.
The new tab model lets you open a new tab with a double-click, or track the selected file as you click around the navigator. You can re-arrange the document tabs to create a working set of files for your current task, and configure how content is shown within each tab. The navigator tracks the open files within your tabs using strong selection.
Navigator font sizes.
The navigator now tracks the system setting for “Sidebar icon size” used in Finder and Mail. You can also choose a unique font size just for Xcode within Preferences, including the traditional dense information presentation, and up to large fonts and icon targets.
Code completion streamlined.
A new completion UI presents only the information you need, taking up less screen space as you type. And completions are presented much faster, so you can keep coding at maximum speed.
Redesigned organizer.
An all-new design groups all critical information about each of your apps together in one place. Choose any app from any of your teams, then quickly navigate to inspect crash logs, energy reports, and performance metrics, such as battery consumption and launch time of your apps when used by customers.
SwiftUI
Using Xcode In Mac Os X For C++ Programming Pdf
SwiftUI offers new features, improved performance, and the power to do even more, all while maintaining a stable API that makes it easy to bring your existing SwiftUI code forward into Xcode 12. A brand new life cycle management API for apps built with SwiftUI lets you write your entire app in SwiftUI and share even more code across all Apple platforms. And a new widget platform built on SwiftUI lets you build widgets that work great on iPad, iPhone, and Mac. Your SwiftUI views can now be shared with other developers, and appear as first-class controls in the Xcode library. And your existing SwiftUI code continues to work, while providing faster performance, better diagnostics, and access to new controls.
Universal app ready.
Xcode 12 is built as a Universal app that runs 100% natively on Intel-based CPUs and Apple Silicon for great performance and a snappy interface.* It also includes a unified macOS SDK that includes all the frameworks, compilers, debuggers, and other tools you need to build apps that run natively on Apple Silicon and the Intel x86_64 CPU.
Updated automatically
When you open your project in Xcode 12, your app is automatically updated to produce release builds and archives as Universal apps. When you build your app, Xcode produces one binary “slice” for Apple Silicon and one for the Intel x86_64 CPU, then wraps them together as a single app bundle to share or submit to the Mac App Store. You can test this at any time by selecting “Any Mac” as the target in the toolbar.
Test multiple architectures.
On the new Mac with Apple Silicon, you can run and debug apps running on either the native architecture or on Intel virtualization by selecting “My Mac (Rosetta)” in the toolbar.
Multiplatform template
New multiplatform app templates set up new projects to easily share code among iOS, iPadOS, and macOS using SwiftUI and the new lifecycle APIs. The project structure encourages sharing code across all platforms, while creating special custom experiences for each platform where it makes sense for your app.
Improved auto-indentation
Swift code is auto-formatted as you type to make common Swift code patterns look much better, including special support for the “guard” command.
StoreKit testing
New tools in Xcode let you create StoreKit files that describe the various subscription and in-app purchase products your app can offer, and create test scenarios to make sure everything works great for your customers — all locally testable on your Mac.

Apple’s Xcode development system is superb for developing applications, but sometimes you just want to write C or C++ code for research or school. Composing a serious chunk of code with vi is no longer acceptable,* so users in this frame of mind are now using Eclipse, a modern IDE, that’s also free. Here’s how to get gcc without installing Apple’s Xcode and then install Eclipse for C/C++ programming.
What’s the Motivation?
At work recently, my wife was chatting with a colleague who was taking his first C++ class. She taught him how to use Eclipse on a Mac, even though he resisted at first. However, later, he came back and commented that the other students were trying to manage ever increasingly complex projects with the vi editor. It was taking them four, six, or even 20 hours in some cases to complete their homework each week. He finished his, typically, in 30 minutes. That’s the power of an IDE with a modern debugger. That last item, the debugger, can’t be emphasized enough. Print statements in your code are oh, so yesteryear with a tool like this. Time is money, and efficiency reflects on you as a programmer.
So if you’re a scientist, researcher or engineer who wants to write some research code, not intended as a GUI app, in Java, C, C++ or Fortran, you need to dump vi as an editor* (or Emacs or Nedit or whatever) immediately and get with this kind of IDE. Things are moving far too fast nowadays not to make this important move. (Clearly, I’m speaking to an older crowd here.**)
To be perfectly clear, Apple’s Xcode is a fabulous development system for C, C++, Objective-C and even Fortran 77***. You can build native OS X and iOS apps. But many researchers and scientists aren’t interested in Xcode. They’ve come from a Linux or other UNIX platform, like IBM’s AIX, and they just want to carry on their research in Eclipse on a Mac. This how-to is primarily for them. But, as I mentioned above, students who are taking their first programming class and own a Mac will also find this discussion useful — indeed mandatory. Remember, this is an introduction to whet your appetite and get you launched, not a complete Eclipse tutorial.
Also, this how-to for the sake of simplicity focuses on C/C++, but Eclipse can handle a myriad of languages, including, but not limited to, Java and Fortran. Let’s start with C/C++.
Getting the gcc Compiler
As an aside, when you install Apple’s Xcode (free from the Mac App Store only in Lion), gcc is automatically installed in /usr/bin. But if you have a mind to work with just Eclipse and gcc, you’ll need a way to install gcc without, if it pleases you, installing Apple’s Xcode first. (For reference, here’s a how-to on installing Xcode and gcc.)
There are at least two places I know of where you can get a gcc installer package for OS X:
- The OS X High Performance Computing page at Sourceforge managed by Dr. Gaurav Khanna at the University of Mass.
If you find other sources, let us know.
Installing Eclipse
Here’s a handy reference on where to get Eclipse for the Mac. Version 3.7 (“Indigo”) installs nicely in Lion and seems to work okay, but our household hasn’t put it to a grueling acid test with OS X 10.7.1.
Eclipse Download for CC++, 64-bit
The download is a …tar.gz file, so move it where you want the Eclipse directory to be because when you double click it, the package will be unzipped and untared right there. After Eclipse is installed, you’ll see it as an app, just like any other, with this icon.
It’s easy to create an alias to eclipse.app, if you wish, and place it in your /Application directory. Because the Eclipse IDE itself is written in Java, if you’re running a clean copy of Lion, you’ll need to download the Java runtime before the Eclipse app will launch. Just double-click on Eclipse, and it’ll trigger the required Java runtime download. Nothing else to do. If you’re in Snow Leopard, the Java runtime is already there.
Java runtime download
This first thing you’ll see when you run Eclipse is that it asks for the location of your workspace. I typically create a directory in /Users/john called Programming where I do any code development. (Which is not much these days.)
Workspace Selection
After you select your workspace, you’ll be confronted with an Eclipse peculiarity. A welcome page will be launched that brings a real feeling of WTF to many users. Here it is.
Welcome screen
The trick is to realize that the icon on the far right, circled in red above, takes you into the workbench. For that named workspace, this one time is the only time you’ll see that screen.
Once the IDE is launched, there are just a few details before you can build a project. Again, for simplicity, lets stay with C/C++. From the Eclipse File menu, select “New” and then C++ Project.
Eclipse — New Project
Experienced Eclipse users know the drill. Name the project, make sure you’ve identified the location of your compiler in the Toolchain, and so on. (It may be different than the default install by Apple’s Xcode. The screen shot below shows Apple’s install of gcc, marked as MacOSX GCC, because I’d previously installed Xcode on that Mac.)

Configuration

Newbies may want to select the Hello World project just to see how things get set up. Make sure you work your way through the setup with Next > at the bottom and don’t click the Finish button too soon. A more detailed examination of this set up and the ins-and-outs of Eclipse are beyond the scope of this getting started article. The goal here is simply an introduction for Mac users. And you’re not alone. There’s a huge body of knowledge on the Internet about Eclipse. Here’s a start.
If all went well, you’ll be in the Eclipse IDE with the Hello World program in the editor and a Make file already created. This environment is called the Eclipse workbench.
Eclipse Workbench w/ default “Hello World” code
It may take you some start-up time to learn Eclipse, but trust me, coding the old way will soon bog you down. The Xcode and Eclipse developers learn from each other, so if you ever decide to get into OS X or iOS development, having earned your wings in Eclipse will pay huge dividends later.
