Working with nRF connect SDK 2.7.0 on IAR Embedded Workbench

[Ruthrapathy]

I am working on a new project which will use nRF Connect SDK 2.7.0. In that most of the code will be ported from legacy project that used IAR Embedded Workbench as IDE (Note: Both new and legacy project uses nRF52840 microcontroller). I could see from the websites that we can use VS code and SEGGER Embedded Studio. But I could not see IAR listed. Is it possible to use IAR for this scenario?

-if yes how?

-if not why?

Hi Ruthrapathy, 

This is mentioned in the documentation for nRF Connect SDK : nRF Connect SDK is IDE agnostic, which means you can use your own IDE if you prefer.

You can use IAR as the IDE, however you would need to use west build systems to build the application. 
As for the question why IAR is not supported, we have to focus on one single build system and it's the same system to build Zephyr RTOS. 
The recommended IDE to be used with NRF Connect is Visual Studio Code. Different from the past with nRF5 SDK that we relied on 3rd party IDEs to support us in developing the IDE and compiler, with VSCode we have a team in Nordic that working on it to build our own build system and integrated in VSCode as the nRF Connect extension.
