App Library shows your apps organized into categories, such as Productivity & Finance, Creativity, and Information & Reading. The apps you use most are near the top of the screen and at the top level of their categories, so you can easily locate and open them.
Tap the dots at the bottom of the screen.
Thumbnail images of your Home Screen pages appear with checkmarks below them.
To hide pages, tap to remove the checkmarks.
To show hidden pages, tap to add the checkmarks.
Tap Done.
With the extra Home Screen pages hidden, you can go from the first page of the Home Screen to App Library (and back) with only one or two swipes.
Note: When Home Screen pages are hidden, new apps you download from the App Store may be added to App Library instead of the Home Screen.
If you have multiple Home Screen pages, you can change their order. For example, you can gather together your favorite apps on one Home Screen page, and then make that your first Home Screen page.
Go to App Library.
Touch and hold the app until the app icons begin to jiggle and the app moves to the Home Screen, then lift your finger.
