How to replace icon view with list view on an iPhone's home page? I dislike selecting programs or other files from a grid of icons ("icon view"), even if their titles are shown beneath the icons. I prefer to select from a scrollable list of titles ("list view"), either with no icons present or if unavoidable then only with a very small icon at the start of each line. 

Is there a way to make my iPhone XR (running iOS 13.3) use list view rather than icon view on its home page?
No, not without any type of jailbreak.

Apple doesn't allow any changes to the default grid view of their iOS/iPadOS devices.

If you have a jailbroken device, you can use tweak like HomeList.  This adds watchOS-type scrolling to the home page.
