WiFi shield not present

Hello, I am using Arduino UNO wifi. UNO sketches are uploaded without any problem , however ESP8266 sketches are not uploaded and give error. On selecting UNO wifi board, network sketches are uploaded however , error is "WiFi shield not present". I believe IDE is unable to communicate with wifi shield.

Thanks

Link to your wifi board so we don't have to guess.
