I am new to ionic. I am facing the issue.

below is my enviorment for this project…

cli packages:

@ionic/cli-plugin-ionic-angular : 1.4.0 (G:\MobileApps\ionic2\soclogin\node_modules\@ionic\cli-plugin-ionic-angular)
@ionic/cli-utils                : 1.6.0 (G:\MobileApps\ionic2\soclogin\node_modules\@ionic\cli-utils)

npm               : 4.6.1

What is the exact command?

To rebuild the Ionic project, to update html files and JS code, you have to use ionic cordova build....

ionic cordova build…

its worked perfectly…

now its working in windows…

for IOS should I do same as
ionic cordova build ios-> then open the xcode project file from platform -> ios folder…

should it will update the same file as well?..
