Cant add IOS platform Error 404 Not Found: IOS@latest


Hi all I have an emergency problem please help ASAP !!!

I built an application win for android, all worked grate.
Now I am trying to build it for IOS on a Mac.
When I run: ionic cordova platform add IOS
I get this Error:

Error: Failed to fetch platform IOS
Probably this is either a connection problem, or platform spec is incorrect.
Check your connection and platform name/version/URL.
Error: npm: Command failed with exit code 1 Error output:
npm ERR! code E404
npm ERR! 404 Not Found: IOS@latest

npm ERR! A complete log of this run can be found in:

[ERROR] Exception:

This is the first time ever I get this error.
I build 10+ apps till now with no problem.
What can be the problem and how can I fix it?
