It crashes using both Swift 4 and Swift 4.2
But if you want to use XCode Version 10.0 beta 2 (10L177m) and Swift 4.2 do not forget to migrate the Swift 4.2 syntax.
Namely,
UIApplicationLaunchOptionsKey > UIApplication.LaunchOptionsKey
UITableViewAutomaticDimension > UITableView.automaticDimension
Otherwise, use XCode Version 9.4 (9F1027a) and Swift 4.
