Zendesk policy on the deprecation of UIWebView
Apple has announced that they will stop accepting submissions of apps that use UIWebView APIs in the ITMS-90809 advisory notice. Accordingly to Apple, new apps submissions containing UIWebView won't be accepted beginning April/2020, and existing apps won't be able to update anymore from December/2020.
Version 2.x of the Chat SDK does not rely on UIWebView, so it is unaffected by ITMS-90809. All Chat SDK iOS customers should plan to upgrade to this new version.
The Answer Bot SDK already uses a WKWebView to render Guide article content, so it is unaffected by ITMS-90809.
Version 4.0.0 and greater of the Support SDK currently use a WKWebView to render Guide article content.
Images will not be shown in Guide articles in the iOS versions of the Support and Answer Bot SDKs when the Help Center is restricted. UIWebView allowed us to authenticate image requests, but WKWebView does not allow this for sub-resource loads. We are actively working on alternative ways of authenticating image requests in WKWebView.
We will publish release notes for each of the SDKs.
