Whether you’re building mobile apps, desktop software, or anything in between, Delphi 11.2 has the tools you need to get the job done quickly and efficiently. In this article, we’ll take a look at some of the most impressive new features in Delphi 11.2 and see how they can help you streamline your workflow. So what are you waiting for? Get started using Delphi 11.2 today!

What platforms does Delphi support?

Delphi is a powerful IDE and software development platform that supports cross-platform development on Android, iOS, macOS, Windows, and Linux. Delphi’s cross-platform support makes it a great choice for developers who need to target multiple platforms with their applications. Delphi’s IDE is also very well suited for developing mobile applications. Delphi applications can be compiled for multiple architectures (depending on the target platform), including ARM and x86. This makes Delphi a versatile choice for developers who want to target multiple platforms with their applications. Delphi’s IDE also includes a number of productivity enhancing features such as a visual designer for creating user interfaces and fast compile times.

Read on to see how conditional compilation allows for handling the edge cases when building single codebases for multiple platforms.

What is conditional compilation?

Conditional compilation is a feature of some programming languages (like Object Pascal) allows code to be compiled conditionally. This can be useful for debugging, optimizing, or porting code to different platforms. For example, if a programmer knows that a particular piece of code will only be used on one platform, they can use conditional compilation to compile it only for that platform. This can result in faster code execution and smaller file sizes. Conditional compilation can also be used to include or exclude code based on user input. For instance, a programmer might use conditional compilation to include code that is only executed when a debug flag is set. This can make it easier to test and debug code without having to recompile the entire program each time. Conditional compilation is a powerful tool that can be used to improve the speed, size, and portability of code.

Does Delphi 11.2 offer enhanced conditional compilation support?

Yes! RAD Studio 11.2 offers enhanced conditional compilation which syntax highlights code that is active for the currently selected platform. This can help you know what code is going to run for the current platform and easily see which code is not going to run on the currently selected platform.

What is the iOS simulator and how does it support iOS development?

The iOS simulator is a software development tool that allows developers to test their apps on a simulated iOS device. This allows developers to see how their app would look and behave on a real iOS device, without having to actually use one. The iOS simulator is available as part of the Xcode developer tools. It can be used on Macs running macOS. The iOS simulator is a valuable tool for developers who want to ensure that their apps are compatible with all iOS devices and operating system versions.

The simulator also has a number of built-in features, such as the ability to simulate different network conditions and device orientations. While the simulator is extremely useful, it is important to note that it does not always accurately reflect the behavior of a real iOS device. Therefore, developers should always test their app on a real device (which Delphi 11.2 also supports) before releasing it to the public.

Delphi 11.2  offers enhanced iOS simulator support on macOS ARM 64-Bit M1 and M2 chips. This has the advantage as running native ARM code which is the same an iOS device. You can interact with your app, rotate your screen, and capture screen shots. This includes the latest iPads.

What debugger does Delphi 11.2 use for Linux applications?

Delphi’s Linux toolchain previously used GDB for debugging. 11.2 switches to LLDB, which provides a strong quality improvement both in features and in Delphi language syntax support. LLDB has been upgraded to version 12 and adopted for the iOS Simulator, along with existing use of LLDB for C++ Win64, and Delphi macOS, iOS, and Android 64 platforms.

Does Delphi 11.2 support Android API Level 32?

Yes! The 11.2 IDE targets Android API Level 32 (up from API level 30 in 11.1), which will be required by Google Play in November 2022. The installer has also been updated to offer the Eclipse Temurin JDK 11, required by the latest Android SDK tools.

What Windows development enhancements do Delphi 11.0, 11.1, and 11.2 bring?

In the latest Delphi 11.0, 11.1, and 11.2 versions Delphi offers many optimizations and quality improvements to the core Delphi RTL. There is also a new TURLStream class, a TStream descendant with support for async operations. Support for Windows 11 and Server 2022 in the TOSVersion data structure.

VCL enhancements to TTreeView, TRichEdit, TEdgeBrowser, TLabelledEdit and TNumberBox, flickering and DoubleBuffering, VCL high-DPI and scaling. New Demo through GetIt showing the use of WinUI 3 library in Delphi. FireMonkey quality improvements to TListView, improved Android SDK integration, TWebBrowser, Windows high-DPI-related issues, and performance.

Is there enhanced Windows EXE security in Delphi 11.1 and 11.2?

Yes! Delphi 11.1 enables a number of PE security flags for Windows applications by default, some of which were previously available but a little hidden. ASLR and other recommended Windows security flags have long been supported by Delphi. In Delphi 11.1, it became easier to use those flags in Delphi by surfacing specific linker options, enabling them by default and also building packages and applications that are part of RAD Studio with those flags enabled.

Does Delphi 11.2 also support building macOS applications including for the Apple M1 and M2?

Yes! You can use RAD Studio to create macOS applications, and you can use your Mac as the required intermediate platform for iOS apps.

From the hardware point of view, in addition to the development PC, you need a Mac connected with the development computer (where RAD Studio is installed); for example, using a local area network (LAN). The Delphi compiler for macOS supports both 64-bit (Intel) and macOS 64-bit (ARM). Delphi also offers Metal as a rendering target on macOS and iOS.
