    With Swift, you can use initWithTransitionStyle:navigationOrientation:options: initializer and pass a value to UIPageViewControllerOptionInterPageSpacingKey in your options parameter to set a space between pages.

    As an example, the following code shows how to implement it with Swift 2.2:

    let optionsDict = [UIPageViewControllerOptionInterPageSpacingKey: 20]
    
    let pageViewController = UIPageViewController(
        transitionStyle: .Scroll,
        navigationOrientation: .Horizontal,
        options: optionsDict
    )
    

    Note that the UIPageViewController class reference states about UIPageViewControllerOptionInterPageSpacingKey:

    The value should be a CGFloat wrapped in an instance of NSNumber.

    However, a Dictionary of type [String: Int], as shown in the previous code, also works.

    check UIPageViewController init method

    - (id)initWithTransitionStyle:(UIPageViewControllerTransitionStyle)style navigationOrientation:(UIPageViewControllerNavigationOrientation)navigationOrientation options:(NSDictionary *)opt

    you can pass your inter page space value to opt in UIPageViewControllerOptionInterPageSpacingKey

    Select the UIPageViewController from the Storyboard. Inside the Attributes Inspector there is an option for setting the Page Spacing.
