I'm trying to create a game in Swift (Xcode 6.4) and I'm getting this error:
EXC_BREAKPOINT (code=1, subcode=0x100695474)
In console:

Any idea? Thank you!
回答1:
Check your IBOutlets and if they are linked to your storyboard.
回答2:
Delete the derived data of your application.
Xcode (top menu) > Preferences > Locations (tab) > Derived Data gives you the path of the folder and simply trash the respective project folder inside that.
Also try cleaning your project if necessary.
