I'm working on an iOS 9 audio unit extension at the moment, that works as intended for debug builds, however I have come across and error code that I can't seem to overcome. I'm hoping that someone else has come across this error and are able to offer any advice. The error I am getting only occurs on release builds distributed through either Crashlytics or the App Store (which, unfortunately, is how i first came across this error). Debugging through the Apple AUv3 demo gives the read out:
Session <UUID> was unable to communicate with the remote service: Error Domain=NSCocoaErrorDomain Code=4099
"The connection to service named <bundleIndentifier>.viewservice was interrupted, but the message was sent over an additional proxy and therefore this proxy has become invalid."
This message appears to be thrown when attempting to load the UI for the audio unit, however I am at a loss on how to progress from here.
Any help or suggestions would be greatly appreciated,
