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.
Document tabs.
IOS 7 & Mac OS X Programming Tutorial - Objective C & Xcode 3.0 (47 ratings) Course Ratings are calculated from individual students’ ratings and a variety of other signals, like age of rating and reliability, to ensure that they reflect course quality fairly and accurately. Since we use VirtualBox for installing the Xcode application on the Windows PC, it is important to use the Virtual machine along with a working Mac OS X. If the installed VirtualBox is not available then it is much easier to download the application from any open-source and free websites. Xcode on Windows PC or Laptop – Installation Process.
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.
Get started with the beta.
Download Xcode 12 beta and use these resources to build apps for all Apple platforms.
The following program is a complete program that uses some math functions:
We create a static library so that we could reuse all the custom math functions for other programs. In this example, we will place the function declaration into libmymath.h. Then, we place the functions for circle in mymath1.c and the power functions in mymath2.c.Note: You can have many C program file with just one header file such as lib.h, lib1.c, lib2.c ... and so on.
Create C Static Library in Xcode
To create static library in Xcode, please fellow the procedure:
On the 'Welcome to Xcode' page, select 'Create a new Xcode project'.
On the template page, select Framework & Libraries >> C/C++ Library. Click Next.
On the options page, enter the name of static library. In my case, it is mymath. Make sure that the type is set to Static. You may want to check 'Use Automatic Reference Counting' if your library implementation contains pointers.
Library Naming Convention
The naming convention of a library package must be prefix with lib follow by the name of the library and the file must end with .a. Therefore a typical library should be named as libmymath.a. However, you can ignore the prefix and the extension when using Xcode. In this case, the library name mymath is alright.Click Next. Then select the file location of your project. Click Create.
Once the project is created you will notice that the target is automatically name libmymath.a.
To create the header file, select File >> New >> File...

On the template page, select 'Header File' and click Next.

On the Save As dialog page, enter the name of header file libmymath.h. Make sure the Targets mymath is checked as shown below. Click Create.
The header file for libmymath.h is as follows:
To create the library implementation file, select File >> New >> File...
On the template page, select C File. Click Next.
On the dialog box, enter the first program as mymath1.c as shown below. Click Create.
The program file for libmymath1.c is as follows:
To create the next implementation use the same procedure as above.
The program file for libmymath2.c is as follows:
To compile the library program, select Product >> Build:
Select
File >> New >> Project.... On the template page select Applications and Command Line Tool. Click Next.
On the options page enter the program name app1. Make sure that the type is set to C. You may want to check 'Use Automatic Reference Counting' if your library implementation contains pointers. Click Next.
Enter the location of your file and click Create.
Include Library File
This is the most important section in this tutorial. To use the static library you've just created, you need to add the static library to your current project.
Method 1
There are many ways to include static library. The fist method is to add all the files from the library project file. Select File >> Add Files to 'app1'....
Navigate to your static library project folder and select the entire folder of the static library. Your project panel should be similar to the one shown below:
Method 2
The second method is to just copy the product (libmymath.a) and header file (libmymath.h). Open your static library project and your application program. Stack them as shown below.
Then drag the file libmymath.h and libmymath.a to your current application project. Check 'Copy items...' and 'Add to targets'. Click
Finish.
Your application project should be similar to the screen below:
Note:
- Method 2 is much cleaner if your static library is very large. If your library implementation is not big, first method is good enough.
- One way to distribute the static library for different user is to copy the header file and the static library to a share folder. Other users will will use Method 2 to copy the library and header files into their project.
- For more complex multiple user scenario, please consult the Xcode user guide.
Create the following application program in main.c:
Running The Application
To run the project, you can click the run button or select Product >> Run. The results should be shown as follow:
Special Note
Please note that the methods are the simplified methods of using static library. Instead of copying files to your projects, you can also change the build settings to reference headers file and library file elsewhere. Please consult the Xcode user guide to explore further options.
