How to set a launch screen image in Xcode

Yes, you can easily set a UIImageView in the LaunchScreen. Simply delete the pre-existing labels from the LaunchScreen.xib, add a UIImageView from the Interface Builder. Assign the following 4 constraints to that UIImageView with respect to the parent view:

• Bottom Space to container
• Top Space to container
• Leading Space to Container
• Trailing Space to Container

And finally set the image to the UIImageView.

Hope this helps you in what you wanted to do.

Update:

Have a look at the following image for further description:

In iOS 8 and later, you can create a XIB or storyboard file instead of a static launch image. When you create a launch file in Interface Builder, you use size classes to define different layouts for different display environments and you use Auto Layout to make minor adjustments.

For adding a launchimage(or any type of image), in Xcode(9.4.1), simply go the Assets.xcassets and you can add it from the self-explanatory addition feature there. For my iphone app, i simply added it, in a jiffy. Also, you need to follow the instructions for adding constraints for the image, as described by one of the answerers with screenshot, above. Finally, you can save and test to see/verify your launch image appearing in the launch of your app.
