Solved in latest beta 8.

Edit: All my text formatting is gone. Hello Scott, As for the alert - it is internal app for Devs, Leads, Sr. Technical Staff. They understand that they need to update the app. Or, I can just show relevant message. I understand what you mentioned regarding urlSession(_:didReceive:completionHandler:). But I cannot read Error object to be able to read the error code -1200 and the error message An SSL error has occurred and a secure connection to the server cannot be made.. Could you please tell me how can I read error object to sure the error (Error instance) is the relevant SSL Error? I mentioned Info.plist way of doing specifically because I would not be adding .pem or .cer file as a configuration item in the app code. Appreciate your response.

The links you provided does not deal with info.plist way. Adding SSL Info in info.plist does not deal with having .cer or .pem file included in the app.
