As the subject says, I need a way to log the negotiated TLS version in an iOS client app.

There isn’t a way to do that. The ideal place for this info is `NSURLSessionTaskTransactionMetrics`, but it doesn’t return that specific bit of info, alas. I encourage you to file an enhancement request for that. <https://developer.apple.com/bug-reporting/> Please post your bug number, just for the record. ps If you use a lower-level API, like `NSStream`, you generally do have a way to get this info. Alas, that won’t help if you’re using `NSURLSession`.
