Reset a playground in Swift Playgrounds on iPad
In some playgrounds in Swift Playgrounds, you can reset changes you’ve made in the playground, all the way back to the starting point. This is especially useful if you want to retry a challenge you already completed or let a friend try it. You can reset the current page or all the pages in a playground.
Note: In a playground created from the Blank template, you can’t reset changes. You can create another playground by downloading another copy of Blank and renaming it. See Create a playground.
Reset a page in a playground
Note: Resetting a page removes the code changes you’ve made on the page and returns the page to its original state. In a playground that supports user modules, resetting a page resets the code in the Main Swift file on the current page (in the tab with 
at the top) but doesn’t reset the shared Swift files in the playground.
In the Swift Playgrounds app
on your iPad, go to the page you want to reset.Tap
, then choose Start Page Over.
