Xojo 2018 Release 4 Is Now Available; Adds Further Modernization and General Updates

AUSTIN, TX, USA (December 11, 2018) — Xojo, Inc., the company that has enabled over 360,000 developers to build native cross-platform applications, today announced the availability of Xojo 2018 Release 4. Xojo is a rapid application development tool for making apps for the desktop (macOS, Windows and Linux), web, iOS, and Raspberry Pi. With over 110 improvements, this release adds some exciting updates, including easier to use modern HTTP support and improvements to Dark Mode.

Xojo is the best environment for professional developers, citizen developers and hobbyists alike. Xojo applications compile to machine code for greater performance and security. Xojo uses native controls so apps look and feel right on each platform. Since one set of source code can be used to support multiple platforms, development is 10 times faster than traditional tools. Xojo comes with a drag and drop user interface builder and one straightforward programming language for development.

“A lot of tools die out because they fail to modernize,” commented Geoff Perlman, Xojo Founder and CEO. “Often modernization efforts are hampered by the fact that you can’t always change things without breaking existing projects, which is something we want to avoid. This release gives the ability to get new functionality and easily integrate it with new code, while not affecting existing projects.”

Xojo 2018 Release 4 includes:

  • The new URLConnection class (part of API 2.0) is an updated version of HTTPSocket and Xojo.Net.HTTPSocket used for web communications
  • New constants AppSupportsDarkMode and AppSupportsHiDPI
  • More Dark Mode improvements to both the IDE and framework
  • iOS builds now use the 12.1. SDK for latest device support
  • macOS builds now use the 10.14 SDK for latest Declare support
  • SQLite updated to 3.25.3
