Answer 1

This error occurs when you build a xib file that has a custom font which is not installed on your build machine. See example below I'm using a custom font called Source Sans Pro Bold my UILabel.

You need to install the custom fonts in your project on the machine that you are building. You can install them via Font Book or copy custom font files into /Library/Fonts.
