Known issues

Bluetooth audio is not supported in this version of the iOS SDK. We are working on an updated version of the SDK to fix this issue.

This version of the OpenTok iOS SDK does not support displaying videos using Apple AirPlay.

In a session with the media mode set to relayed, only one client can subscribe to a stream published by an ioS device.

The Xcode iOS Simulator does not provide access to the camera. When testing in the iOS Simulator, an OTPublisher object uses a demo video instead of the camera.

Subscribing to screen-sharing streams (see "New features and changes - Version 2.4") is not supported in the OpenTok iOS SDK version 2.3 and older. You must upgrade to version 2.4.

Do not use the -all_load linker flag. Instead, use the -force_load linker flag to load specific libraries that require it.

The OpenTok iOS SDK links to the libc++ standard library. If another library that links to the libc++ standard library was compiled in a version of Xcode older than 6.0.0, it may result in segfaults at run time when using it with the OpenTok iOS SDK. Known incompatible libraries include, but are not limited to, Firebase (versions earlier than 2.1.2 -- see and Google Maps (versions earlier than 1.9.0). To fix this issue, download a version of the other library that was compiled using Xcode 6.0.0 or later.
