Answer 1

In addition to doing the following, you may experience this issue if your app's Storyboard's files are localized. First, do each of these:

• Clean Build
• Reset Simulator
• Restart Xcode
• Delete your DerivedData folder in ~/Library/Developer/Xcode/DerivedData
• Restart Computer

What finally worked for me was re-generating the storyboard localization files and deleting the English localization (which was unneeded because the Base Locale is English). To reload your Storyboard strings, see this answer on StackOverflow.

I had noticed that the non-text parts of my Storyboard were being updated, but not the localized text. If you have a localization in your app, I would recommend checking to make sure your localizations are updated (even if they're .strings files).
