Questions tagged [delphi-10.3-rio]

Delphi 10.3 Rio is a specific version of Delphi released in November 2018.

Delphi 10.3 Rio supports development of applications covering 32-bit and 64-bit, 32-bit, 32-bit and 64-bit, 32-bit, and server 64-bit. Windows applications may be built using either the framework or the (FMX) framework, whereas the OSX and mobile platforms are built under the FireMonkey framework only.

This version of Delphi brings several enhancements to the core Delphi pascal language, including inline variable declarations and type inference, as well as RTL performance improvements, and changes to Delphi's ABIs for better C++ interoperability across all platforms. It also sports several IDE UI redesigns, better High-DPI support to the VCL, support for iOS 12 and Android API level 26+, and begins Embarcadero's push to phase out its ARC memory management model for TObject classes, starting with the Linux 64-bit compiler.
