during the progress of my app I decided to change from using a UIStoryboard to .xib file, and now I get the error:
Could not find a storyboard named 'Main' in bundle NSBundle
How can I fix this problem within the Simulator part of my app?
Remove the "Main storyboard file base name" or "UIMainStoryboardFile" Key from your info.plist file.
Click Your Story board
then do step 2 and step 3
