I'm trying to complete the "Build a Mobile Insurance App with Swift and the Salesforce Mobile SDK for iOS" trailhead but I'm stuck. I've installed the package in my Trailhead Playground, and created the XCode project from the repository link. I refactored the NewClaimViewController+Uploading.swift file like they say to to call uploadPhotos and uploadAudio asynchronously (code pasted in comment) and added my playground domain to the app login. When I log into the app from the simulator, i get the message "Server Error Can't connect to the server: An SSL error has occurred and a secure connection to the server cannot be made." If I click OK, it moves forward with the sign in but the Claims landing screen loader spins endlessly. I can click the plus sign to make a claim, but again when I hit submit, again I get an endless spinner and the record is not created in the playground.
