Can I test icons without an update?

No, you must include all alternative icon assets in your app binary and submit a new version to the App Store before running a PPO test.

How many icons can I test?

You can test up to 3 alternative icons against your control icon (4 variants total) in a single Product Page Optimization test.

Does Xcode require specific settings?

Yes, you must set 'Include All App Icon Assets' to 'Yes' in your Build Settings to ensure alternative icons are included in the release.

How to Test App Icons with PPO: Step-by-Step Guide

To test icons using Product Page Optimization (PPO), you need to include all icon variants in your app build in advance.
You can do this in Xcode in 3 simple steps:

Add the icon to your project

Open your project in Xcode.
Go to the Assets.xcassets file.
Right-click → New App Icon.
Name the icon, for example, AppIconAlt1.
Upload images of all required sizes (Usually, the icon size is 1024x1024 pixels. Xcode will show which exact sizes you need to upload).

Make sure all slots are filled-otherwise, the icon will not be accepted.

Check your project settings

Open the project’s Build Settings tab and check the following parameters:

Primary App Icon Set Name → set to AppIcon (or your main icon name).
Include All App Icon Assets → set to Yes (includes all found icons in the build).

The Alternate App Icon Sets field can be left empty-this is optional.

Build a new version and submit the app for review

Build the app as usual.
Submit the new version to the App Store via Xcode or Transporter.

Launch PPO

After publishing the new app version, launch Product Page Optimization.
