Description

C# Coder is a development tool for C# that lets you create, build and debug C# programs directly on your iOS device with the power of from the Roslyn Project.

The app compiles and runs your programs directly on your device - no internet connection si required. The built-in C# interpreter is optimized for iOS and gives you the full power of C# right on your device.

Writing programs have never been easier - our new editor helps you with great code completion and other extras.

Technical details:
- The app interprets compiled code stored in memory, no machine code is generated or stored on the device.
- The app does not yet support the concept of projects - a program is always contained in a single file.

Limitations:
- It's not possible to build executables that can be distributed.

DISCLAIMER: This is cutting edge technology and I expect some complex C# language features to be incomplete. Do not use any of the results of your code or program output in any kind of production environment.

NOTE: The CareKit and HealthKit APIs are supported in your C# programs but are not used by the app itself for collection data or reading data from your device.
