Microsoft Word Quit Unexpectedly Mac Sierra

Hello Keith,
Thank you for using Apple Support Communities.
I see that your Microsoft Word app is unexpectedly quitting after an updated of the operating system. You question is confusing as you say in the subject and text that it is in 'iOS', but you are posting the question in the macOS High Sierra forum.
If the issue is occurring on an iPhone or iPad running iOS, then this article should help you with the issue:
If an app unexpectedly quits, stops responding, or won’t open
If however, the issue is on a Mac computer running macOS High Sierra, then I would take a look at this support article from the Microsoft Support site:
Word for Mac closes unexpectedly or error 'The application Microsoft Word quit unexpectedly'​
Best regards.
