Hi Dhirendra,

Thank you for your question.

In our opinion, the response is very subjective to your needs and platform dependency. If you are looking for a simple eCommerce App, ReactNative can do the job. If you are looking for something that talks to most of the physical aspects of the device, then building the app on Swift or Java can be recommended.
