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.

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.

It installed Xcode by automatically downloading it and installing. All errors and problems (I had) were gone after the reinstallation. This solution worked for: Xcode 5.0.1 on Mac mini, Mac OS X 10.9.1. Other solutions considering sudo commands did not work for me. I don´t know how Xcode 5 was installed. Xcode was located in the Applications. Learning c programming mac create a c program basic proframming xcode ! - download xcode. Jul 02, 2013. Feb 15, 2012. Instruments (formerly Xray) is an application performance analyzer and visualizer, integrated in Xcode 3.0 and later versions of Xcode. It is built on top of the DTrace tracing framework from OpenSolaris, which was ported to Mac OS X v10.5 and which is available in all following versions of macOS. Instruments shows a time line displaying any event occurring in the application, such as CPU. This version includes the SDKs for iOS 14, iPadOS 14, macOS Catalina, tvOS 14, and watchOS 7. Download from the Mac App Store.

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

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.

Installing a C++ Development Environment for OS X (Xcode or Xcode/jGrasp)

1 Introduction

There are an enormous number of development environments for C/C++ programmers, some of which are freely available and some of which are commercial products.

This document describes the installation and use of two freely available environments under OS X, one that consists of:

• Xcode

and one that consists of:

• Xcode
• jGrasp

jGrasp is less-sophisticated than Xcode but easier to use.

2 Getting Started

The first thing you need to do is register with Apple:

Then you need to download the Xcode installation files:

If you are going to use jGrasp as your integrated development environment (IDE) you need to also download:

3 Installation of Xcode Only

Installation is fairly straightforward:

1. Install Xcode.

You are now ready to start developing in C/C++ using Xcode as your IDE.

4 Installation of Xcode and jGrasp

Installation is fairly straightforward:

Xcode On Mac

1. Install Xcode.
2. Install jGrasp.
3. Run jGrasp.
4. Click on Settings, pull down to Compiler Settings, and pull down to Workspace.
5. Change the language to C++.
6. Select 'c++ (g++) - Mac OS X' or 'g++ - generic', click on Use, and click on OK.

You are now ready to start developing in C/C++ and you have two ways to proceed, depending on your personal preferences. You can use jGrasp as your IDE or you can use Xcode as your IDE>

5 Testing the Installation Using jGrasp

To test your installation using jGrasp:

1. Run jGrasp.
2. Click on File, pull down to New, and pull down to C++.
3. Copy and paste the following fragment: into the editing window.
4. Click on File and pull down to Save As and name the file testing.cpp.
5. Click on Build and pull down to Compile and link.
6. Click on Build and pull down to Run.

Depending on what else is installed on your computer, this will either cause the message 'Testing 1, 2, 3' to be written into the jGrasp Run I/O window or will open a command shell window and execute the program there.

How To Download Xcode

6 Working from within jGrasp

You can compile, link and run applications written in C++ from within jGrasp. However, because of the nature of the C++ development process, it is not as simple as it is with applications written in Java.

Xcode Download C Mac Instrument

The Build menu contains the entries Compile, Compile and Link, Make, and Run (among others). The Compile entry can be used to compile an individual source file. The Compile and Link entry is not very useful because the process of indicating which files should be linked is akward. Hence, it is best to use the Make entry.

The Make entry simply calls the make utility (which must be in your path -- see the discussion in the installation instructions above). The make utility uses a makefile (with a default name of makefile) in the working directory. You can, of course, create/edit this file with jGrasp.

Note that when you run an application from withing jGrasp it assumes that the executable is named a.out.

7 Issues

You should be aware of the following issues:

1. Many applications (including many development tools) use the space character as a delimiter. This means that, in general, it is a bad idea to use spaces in file names and/or directory names.
2. See 1.
