Icons and the file

From iOS 11 Apple now requires a new process of adding icons to your application, you can no longer simply package them as you have done with previous versions of iOS and AIR. Instead you need to create an “” file and package in the root directory of your application.

Note: The file is need for iOS 11+ when you are using AIR SDK v28+

Method 1: Online tool

This is the simplest way if you are a Windows developer.

Simply go to the following url:

and upload a 1024x1024 image of your icon. You will get a zip download containing the file and all the icon sizes needed to embed in your iOS application.

Method 2: Command Line

It uses the same directory structure (Assets.xcassets) as in your Xcode application however uses the command line to convert this into the, so you can simply replace the files in the directory and run the script to create your

xcrun actool Assets.xcassets --compile build --platform iphoneos --minimum-deployment-target 8.0 --app-icon AppIcon --output-partial-info-plist build/partial.plist

Launch images

Recently Apple changed the supported names of the files for the default / launch images. Make sure you have correctly added the default images according to the Adobe docs:
