Stack traces, symbols or other ways to collect crash information for iOS?

So usually when you develop for iOS and make builds, you store symbols externally (app.dSYM folder) or internally (inside of IPA). Symbols let you later decode stack traces from crash logs, which is still very important for final shipping appstore builds (iTunesConnect will deliver crash logs from end-users if the ipa has symbols) and internal QA Adhoc builds (Services like HockeyApp can collect crash logs and symbolize them automatically).

Since UE4 removes stack trace information for “Shipping” builds and produces no symbols, what’s the recommended way to get information about crashes for iOS builds?

Is there a way to enable stack traces (sacrificing some performance) and make UE4 generate symbols?
Is there a way to make UE4 generate symbols that are stored internally in IPA?
