So you need to find the IBDesignablesAgent-iOS_[Date]_[YourMac].crash on ~/Library/Logs/DiagnosticReports this location and you will get the reason of the crash with the respected file path.

Try to disable 'Use Trait Variations' (Identity and Type panel) for any xib file that you might have for custom views that are used in your storyboard.

I had the same issue and came here to try and figure out what happened. I noticed the top rated answer and the answer itself didn't help me, as IBDesignable didn't exist in the log folder and I already attempted all other options there, however in the comments I noticed someone talking about a frame init.

I decided to try commenting out my IBDesignable extension for UIView and it instantly fixed the problem. So, to fix this, find the extension causing the issue and make sure to set up the required inits by creating an IBDesignable class and providing the required initializers as follows:

@IBDesignable class RoundedView: UIView {

override init(frame: CGRect) {
    super.init(frame: frame)
    sharedInit()
}

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    sharedInit()
}

override func prepareForInterfaceBuilder() {
    super.prepareForInterfaceBuilder()
    sharedInit()
}

func sharedInit() {
}
}

IMPORTANT: remember to add the new class to the item you are using the designable on.
