How To Run A C Or C++ Program On iOS

A fast and reliable C and C++ Compiler and IDE for app development software for iOS is very important for beginners and professionals alike, whether they are developing C++ for iOS or for any of the other operating systems and targets. The C and C++ programming languages are subjectively the World’s most powerful programming languages and consistently appear in the World’s top three most popular programming languages. Thanks to its huge range of ready-made variables, functions, methods, namespaces and libraries it’s the do-everything toolkit which can be used for everything from regular simple apps to low-level operating system drivers, IoT hardware control and everything in between. When a user wants to develop modern C++ applications, she or he will benefit from investing a very small amount of time in becoming familiar with the functions, features and shortcuts of a professional IDE. A small effort in that area pays dividends in productivity. In this post we explain basic of using C++ Builder to create an iOS app as a guide for beginners.

What is a good IDE for creating a C++ program for iOS?

Do you know that you can develop C/C++ iOS Apps on Windows 11 with the latest RAD Studio / C++ Builder? C++ Builder supports all C commands and CLANG LLVM, C++ 17 standards. RAD Studio with C++ Builder and Delphi is a great IDE and compiler running on Windows that supports multi-device applications for different platforms including iOS and you can develop native ARM applications for M1 Silicon CPUs used in the latest Apple hardware too. So, your application’s program code can be recompiled so that it runs on everything from the latest Windows 11 version as well as on Apple ‘desktop’ devices such as the MacBook laptops, Mac Minis and iMacs using either Intel processors or the new M1 ‘Silicon’ CPUs. Yet that same program code can almost entirely be reused with little or no changes so it may be compiled for iOS where your apps can run on the very latest iPhone devices. Everywhere your users are, your C++ and Delphi apps can be.

How to run a C++ program in an IDE?

C++ Builder IDE has mainly 5 Parts, the Code Editor Window and Form Designer, Projects Window, Palette Window, Structure Window, Object Inspector Window. You can find more , less commonly used windows from the main IDE menu as well as the right-click context menus. All the basic sections can be summarized in this IDE picture;

How To Run A C Or C++ Program On iOS Parts of the IDE
Basic sections of RAD Studio IDE

Now let’s explain each of these areas shown above.

1.The Code Editor and Form Designer: The Code Editor and the Form Designer occupy the center pane of the IDE window. The Code Editor is a full-featured, customizable UTF8 editor that provides syntax highlighting, multiple undo capability and context-sensitive help for language elements. You can switch between them by using F12 or from lower tabs in IDE. As you design the user interface for your application, RAD Studio generates the underlying code. When you modify object properties, your changes are automatically reflected in the source files.

2. The Project Window : The Project Window displays and organizes the contents of your current project group and any project it contains. You can perform many important project management tasks, such as adding, removing, and compiling files. The default location of the Projects window is the upper right corner of the IDE, but the window is dockable, as are many windows in the IDE

3. The Tool Palette Window: The Tools Palette Window has UI elements, components that can be used in application UI design, it assists with a new project, adds components to a form, or adds code snippets to the Code Editor.

4. The Structure Window: The Structure View Window displays a tree diagram that shows the hierarchy of elements in the active window (that is, the Code Editor or the Form Designer)

5. The Object Inspector Window: The Object Inspector is used to examine and edit the properties and events for the currently selected object or objects. Every design object (Components, UI Elements) can be edited by clicking on it then setting its properties and events in the Object Inspector Window.

Running C++ Code: You can Run your code by pressing F9 or Run button on the top bar. You can use other Run Without Debugging. There is a Stop and Pause button if your code is in loop. On the run time you can use debug, break points, watch variables and many other runtime features.

Switching between the Design and Code View: You can press F12 to switch between the Code Editor and Form Designer. The latest C++ Builder also allows you to use both of them together in the same screen. You can switch code, header and design view from the bottom top bars.

Switching Between the Code Files: You can use tabs on the top to switch between .c or .cpp files and .h headers.

How to run a C++ program project for iOS?

C++ Builder greets you with a Welcome Screen. You can create a new project by using File->New menu on the top. By using this menu. You can create a new MultiDevice Application in C++ Builder with FireMonkey framework or a new Windows VCL Application in C++ Builder with VCL framework or you can create a Console Application in C++. There are more options to develop more professional static, dynamic libraries.

When you create a project this will create a Project source code file and a Unit which has a visual window. Your project will have .bpr, .cpp, PCH.h files, this project also includes two more .cpp and .h units. You can start designing your app with this ready-made unit as launching point, adding your own code by modifying these Unit files and its .h header. You can add more Units with new .cpp and .h files in your project..

If you forget to install iOS support don’t worry, RAD Studio / C++ Builder allows you to install these packages from the IDE. Just run RAD Studio / C++ Builder go to Tools -> Manage Platforms … then check C++ Builder iOS Enterprise option. See Additional Options tab, select Samples and Help or any other options needed, then press Apply. This will Install the latest iOS development packages for the C++ Builder.

Step 3. Create a new C++ project to develop iOS apps on Windows

If you download C++ Builder Community Edition (or RAD Studio CE version) or any Professional, Architect, Enterprise versions of C++ Builder. Install it on your Windows computer and run RAD Studio or C++ Builder.

1. Choose File->New-> “Multi Device Application- C++ Builder” menu

How To Run A C Or C++ Program On iOS Choosing to create a multi device application

2. Select Blank Application to develop application with a blank form UI. You can add many UI components on it later.

How To Run A C Or C++ Program On iOS Create a blank multidevice application

3. Save all Unit File and Project file to a folder by using File -> Save Project As .. menu. For example: Folder name can be MyIOSApp and Unit file name MyIOSApp_Unit1.cpp and the project name MyIOSProject_Project1

Step 4. Change your platform to iOS

On the right side there is Project window which lists platforms for this project. Multi-Device projects can be compiled for Windows, iOS or Android, the default is Windows 32-bit. To see these OS platforms, click the > icon on the left of Target Platforms section. This will show platforms, then double click to activate iOS Device 64-bit. After this all compilations will be done for the iOS platform. Anytime, you can back to Windows or Android and you can compile your project for that platform too.

Step 5. Add your UI items to your form design

In C++ Builder, you can add your UI elements (also called as components) by dragging them from your Palette Window. There are many visual and non visual components for the C++ Builder. For example, you can drag a Memo (TMemo) component to see outputs visually and a Button (TButton) to receive click, given as below,

Step 6. Add your C or C++ code to develop iOS apps on Windows

Note that you can easily switch between UI Form Design and Code Area by using use F12 key. Or you can also use tabs below the IDE. You can easily switch between .cpp, or .h header codes and Design.

If you did 3rd part of Step 4, now, you can modify inside of Button1Click() as given example below,

This example above is a modern “Hello World” example for iOS which runs with C++ Builder. Modern applications have a GUI. Note that VCL projects are Windows only. FireMonkey projects are Multi Device (multi-platform) applications that you can compile and run on Windows, MacOS, iOS and Android.

Step 7. Install PA Server to develop iOS apps on Windows

The Platform Assistant server (named paserver) is a command-line application that can be installed on Windows, macOS, and Linux. You install the Platform Assistant on a remote system, in the same network as your development system, to let RAD Studio interact with that remote system, so that you can develop cross-platform (multi-device) applications for macOS, iOS, Linux, or Win64 (this last from a Win32 development system). The Platform Assistant allows you to develop multi-device applications and to debug applications remotely.

The Platform Assistant needs to be running and connected to the IDE in order for you to do the following:
