Apple iOS overview
iOS brings a fresh look to the things you do most often, making them easier than ever. New features help you get what you need in the moment. And the apps you use all the time become even more intelligent, more personal, and more private.
What’s new in version 18.4
New Features
- AdAttributionKit now supports Overlapping Conversions, which enables advertisers to have multiple simultaneous re-engagement conversions. The system provides a conversion tag as the value of the re-engagement URL parameter. You can pass the conversion tag into the updateConversionValue API to update the specific conversion. (136100247)
- New AdAttributionKit testability for advertised apps is in iOS Settings > Developer > Ad Attribution Testing. You can now create and interact with development postbacks for your app in iOS Settings, instead of requiring a separate publisher app to sign and show ads for your app. If your app is built with Xcode, you can now create development postbacks for your app in iOS Settings, replacing the need for your app to first be distributed in the App Store or alternative app marketplace.
