A way to easily safely unwrap values

Optional+Unwrap.swift

extension Optional {
    
    /**
     Unwraps a value or returns the default value provided if it's nil
     - parameter defaultValue: The default value that will be returned if the original value is nil
     */
    func unwrap(defaultValue: Wrapped) -> Wrapped {
        guard let self = self else {
            
            // Make the app crash in debug but not in production
            assertionFailure("nil value")
            return defaultValue
        }
        return self
    }
}
