App Transport Security

App Transport Security (ATS) is a privacy feature introduced in iOS 9. It's enabled by default for new applications and enforces secure connections.

All iOS 9 and iOS 10 devices running apps built with Xcode 7 or higher that don't disable ATS will be affected by this change. This may affect your app's integration with the Google Mobile Ads SDK.

The following log message appears when a non-ATS compliant app attempts to serve an ad via HTTP on iOS 9 or iOS 10:

App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app's Info.plist file.

To ensure your ads are not impacted by ATS, do the following:

1. Update to version 7.15.0 or later of the Mobile Ads SDK.

2. Add the NSAllowsArbitraryLoads, NSAllowsArbitraryLoadsForMedia, and NSAllowsAribtraryLoadsInWebContent exceptions to your app's Info.plist file to disable ATS restrictions.

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
    <key>NSAllowsArbitraryLoadsForMedia</key>
    <true/>
    <key>NSAllowsArbitraryLoadsInWebContent</key>
    <true/>
</dict>

The NSAllowsArbitraryLoads exception is required to make sure your ads are not impacted by ATS on iOS 9 devices, while NSAllowsArbitraryLoadsForMedia and NSAllowsAribtraryLoadsInWebContent are required to make sure your ads are not impacted by ATS on iOS 10 devices.
