SwiftUIPager

SwiftUIPager provides a Pager component built with SwiftUI native components. Pager is a view that renders a scrollable container to display a handful of pages. These pages are recycled on scroll, so you don't have to worry about memory issues.

Create vertical or horizontal pagers, align the cards, change the direction of the scroll, animate the pagintation... Pager lets you do anything you want.

Usage

Initialization

Creating a Pager is very simple. You just need to pass:

• Array of items
• KeyPath to an identifier.
• ViewBuilder factory method to create each page

Pager(page: $page
      data: items,
      id: \.identifier,
      content: { item in
           // create a page based on the data passed
           self.pageView(item)
 })

UI customization

Pager is easily customizable through a number of view-modifier functions. You can change the orientation, the direction of the scroll, the alignment, the space between items or the page aspect ratio, among others:

By default, Pager is configured as:

• Horizontal, left to right direction.
• Items have center alignment inside Pager and take all the space available
• Current page is centered in the scroll
• Only the page is hittable and reacts to swipes

Use itemAspectRatio to change the look of the page. Pass a value lower than 1 to make the page look like a card:

whereas a value greater than one will make it look like a box:

Add a position alignment to itemAspectRatio to specify the alignment inside Pager:

Pager(...)
     .itemSpacing(10)
     .padding(8)
     .itemAspectRatio(1.5, alignment: .end)

By default, Pager will create a horizontal container. Use vertical to create a vertical pager:

Pager(...)
    .vertical()

You can customize the alignment and the direction of the scroll. For instance, you can have a horizontal Pager that scrolls right-to-left that it's aligned at the start of the scroll:

Pager(...)
    .itemSpacing(10)
    .alignment(.start)
    .horizontal(.rightToLeft)
    .itemAspectRatio(0.6)

Animations

Use interactive add a scale animation effect to those pages that are unfocused, that is, those elements whose index is different from pageIndex:

Pager(...)
    .interactive(0.8)

You can also use rotation3D to add a rotation effect to your pages:

Pager(...)
    .itemSpacing(10)
    .rotation3D()

Events

Use onPageChanged to react to any change on the page index:

Pager(...)
     .onPageChanged({ (newIndex) in
         // do something
     })

Sample projects

You can use Pager to implement cool effects as in iPod
