We are asking all developers to be prepared to update their iOS apps to the latest version of the Google Cast SDK (v4.4.4) to be released on August 15, 2019
With the upcoming release of iOS 13, Apple is providing additional privacy controls which will cause new authorization dialogs to appear to users of apps that use the Cast iOS SDK.
We understand that triggering new dialogs may not be ideal for your app. To address these concerns and to improve how the SDK will work with iOS 13, the Google Cast team is implementing changes in our upcoming releases to ensure this change by Apple does not impact your app or your users’ experiences.
We will make two versions of the Cast iOS SDK available to developers:
One which includes Guest Mode support
The SDK with Guest Mode will prompt a new Bluetooth®-related permission.
One which excludes Guest Mode support
The SDK without Guest Mode will not prompt any new permissions for Bluetooth®.
In addition, some system-level APIs relating to device discovery will change behaviors in iOS 13, and we’ll update the Google Cast SDK in the coming weeks accordingly. We strongly recommend that you update your apps to the new SDK to avoid a degraded experience on iOS 13.
We appreciate your continued support as we make these changes. Additional details can be found at:

Thanks,
Google Cast SDK Team
