XML Error: Unquoted attribute value

Question

Whenever I run the ionic cordova build ios command I get the following error

I have gone to the line of text where it states to have an unquoted attribute value and nothing seems out of the ordinary.

<platform name="ios">

Answer 1

The XML you've posted is well-formed once you add an end tag for platform.

We can only guess since you've not included the errant part of your document, but chances are that you've made one of the following mistakes around an attribute value:

1. Omitted (single or double) quotes.
2. Used a curly quote “/” rather than straight quote ".
3. used a curly apostrophe ‘/’ rather than straight apostrophe '.
