PhoneRTC doesn't currently support 64 bit devices. From 1st February 2015, Apple requires all iOS apps to support 64 bit devices.
Therefore, very soon PhoneRTC will no longer be a viable option for including video chat in an iOS application. This issue has been reported on PhoneRTC's repository on Github, but so far nobody has taken it on.
Does anybody know of either a way that PhoneRTC can be made to support 64 bit devices, or a suitable alternative?
