iOS 13 - 我们可以使用 xib 作为启动故事板的启动屏幕吗？

Question

As Apple announced during WWDC with their new requirement that by April 2020, all apps should adopt Launch Storyboards because they will be deprecating launch images.

My question is, can we use a launch screen xib file over a launch storyboard file? Or is there another reason why they recommend specifically using a launch storyboard because storyboards are usually faster and allocate less memory?

From Apple documentation:

In iOS 13 and later, always provide a launch storyboard for your app. > Don't use static launch images.

Answer 1

Found my answer! With the release of XCode 11 beta 4 yesterday, Apple included the following in their release notes:

Your app might fail to build if it contains a launch image. The failure message resembles the following: “The launch image set named did not have any applicable content.” Launch images are deprecated and should be removed; use a launch storyboard or .xib file instead. (50210495)
