Ionic : can not build an ios app - FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

Ionic Framework ionic-v3
1

till date build command is working fine with

ionic cordova build ios -l -- --buildFlag="-UseModernBuildSystem=0"

but now its throwing error of CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory
I found command to resolve this issue but its still not working

ionic cordova build ios -l -- --buildFlag="-UseModernBuildSystem=0" --max_old_space_size=4096

I got these error in both command
