Create Amazing Cross-Platform Applications
80% of Internet users own a smartphone and access application and data from both their mobile device and their laptop/desktop, so it’s more important than ever that your apps run on both.
With RAD Studio 10.3, mobile platform development support is provided in all Professional, Enterprise and Architect editions. RAD Studio developers code once, compile natively for each platform, which reduces the time and effort of learning multiple languages and managing parallel development cycles.
New in 10.3:
Android API26 support, meeting Google Play Store requirements for new apps in August 2018 and updated apps in November 2018.
Android Native Controls and FMX styled controls on the same Android form, including using material design theme for Android 5.0 or higher
iOS 12 Support (32- and 64-bit) for building App Store and enterprise applications.
Support for Unicode Emoji
Code Your Way
With two new themes, customizing your IDE to match your coding style has never been easier.
Dark and Light Themes Whether you like to code at night or during the brightest times of days, RAD Studio’s Light and Dark themes have you covered. Dark themes have been reported to reduce eye strain in low light environments, allowing you to work more productively at night. It’s easy to toggle between dark and light themes via a toolbar menu.
Customize Your Development Environment The improved installer UI and license manager UI help you identify the options you need and skip what you don’t, whether you’re developing for multiple platforms or just one.
Clean, Updated IDE UI Find the options you need, fast. The IDE’s main window is more readable and aligned. Easily tell where the keyboard focus area is with updated changes to focus background colors. Editor tabs are larger with easier to read fonts, so you can quickly make changes and keep coding.
Stunning Windows Applications with VCL
The Visual Component Library (VCL) offers easy and visual development of the application user interface, and 10.3 brings new updates to keep your apps looking modern and fresh.
Enhanced HighDPI Support. With the new VCL High DPI ImageList control in 10.3, developers building new VCL Windows applications or updating existing apps for high DPI displays can fully support multi-resolution, pixel perfect images on all controls, as well as any custom drawing requiring scaled images for multiple resolution monitors.
Per Monitor V2 Support. Ensure your app scales correctly for all Windows scaling, by responding to DPI scaling changes on different screens at runtime.
Expanded Windows 10 and WinRT API Support. This includes a number of key WinRT APIs and recent Windows 10 APIs, including ready-to-use components for in-app purchases and trials in the Windows 10 Store
