I resolved it looking for in ./hooks folder. I found hookArgs.platform.toLowerCase() and I had to change to (hookArgs.platform || '').toLowerCase();

@sputn1k,

Try the following:

rm -rf node_modules hooks platforms && tns run ios

@sputn1k,

Can you execute the command with --log trace (tns run ios --log trace) and send us the produced log ?

This issue is probably caused by plugin hooks which are not compatible with NativeScript 6.0.0. @Oscarato fix is what should be applied in the plugin itself.
As there's nothing to do in the CLI, I'm closing this issue.
