I may have solved my issue. In the initialization of the SDK, the online documentation includes this:
let initParams = ZMVideoSDKInitParams()
initParams.domain = "zoom.us"
initParams.enableLog = true
But, what is not indicated is that if you do not supply a logFilePrefix then SDK initialization will fail. Be sure to include that in your setup. This differs from the iOS SDK which does not require the log file prefix to be set.
let initParams = ZMVideoSDKInitParams()
initParams.domain = "zoom.us"
initParams.enableLog = true
initParams.logFilePrefix = "ZoomSDK"
Fabulous work, Zoom team… maybe updating your documentation and sample projects should be a higher priority.
