Cordova corrupt ios platform - ios

Question

I am trying to add some ionic native elements e.g. 'ionic cordova plugin add cordova-plugin-camera' but i get a err due to the ios platform not being there.
running cordova platform version ios I get:
Installed platforms:
android 6.3.0
ios
Available platforms:
blackberry10 ~3.8.0 (deprecated)
browser ~5.0.0
ios ~4.5.1
osx ~4.0.1
ubuntu ~4.3.4 (deprecated)
webos ~3.7.0
windows ~5.0.0
www ^3.12.0
So I have ios installed however do deal with this problem i've run cordova platform rm ios
then cordova platform add ios but I get this error:
Using cordova-fetch for cordova-ios#0.0.1
Error: Failed to fetch platform cordova-ios#0.0.1
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 ETARGET
npm ERR! notarget No matching version found for cordova-ios#0.0.1

I assume this has something to do with the ios platform not having a version associated with it but I can't figure it out.
ionic -v
3.19.0
PART 2 UPDATE
the first step results in:
rm: could not remove file (code EACCES): /Users/adamgoldberg/Documents/programming/thrive/platforms/ios/cordova/node_modules/ios-sim/node_mod
ules/.bin/nopt

rm: could not remove directory (code ENOTEMPTY): /Users/adamgoldberg/Documents/programming/thrive/platforms/ios
and then the second line ionic cordova platform add ios#latest results in
Using cordova-fetch for cordova-ios#latest
Error: Platform ios already added.

Answer 1

Remove ios platform
cordova platform rm ios
Add platform via
ionic cordova platform add ios#latest
Add cordova-plugin-camera plugin
ionic cordova plugin add cordova-plugin-camera --force
Update 2:
Try with "sudo cordova platform rm ios" ,
Then remove "ios" platform from "config.xml" file if exits,
Then remove "ios" folder from physical path as well if exits,
After above three steps
ionic cordova platform add ios#latest
ionic cordova plugin add cordova-plugin-camera --force
If you will get same error(EACCES) again then try all command with "sudo"
