The blockly-ios project is no longer actively developed by the Google Blockly team. If you are looking to create a new Blockly-based app, we recommend using the web version in a WebView. We have also create an XCode demonstration project that does exactly this.

Blockly for iOS

Blockly is a library for building drag-and-drop visual editors for JavaScript, Python, Lua, and several other programming languages.

Blockly for iOS is similar to its web counterpart in terms of API, but is:

• Optimized for native iOS performance and easier integration in iOS apps
• Written in Swift, with backwards compatibility for Objective-C projects
• Designed with better touch support, such as custom input controls and multi-touch

Here is a demo of using Blockly for iOS to program a “turtle”:
