对于发行版，iOS中正确的“ Strip Debug Symbols”设置是什么？

Question

I've been getting a bunch of crash logs for my (largely c++) app on iOS. My problem is I can't seem to ever symbolicate these crash reports properly.

What is the "proper" setting for stripping debug symbols for release on iOS? I get that you'd want to strip the debug symbols so the download size of the app isn't ridiculously large.

But the problem is that it seems to make the crash reports virtually unreadable.

Do dSYM files on the xcode archives get sent and eventually downloaded by the users?

Or is it simply something to be kept for future symbolicating purposes (done locally on my own machine, on xcode)?

This. Your "release" config (or whichever config you use for distribution) should have the following setting:

Symbols Hidden by Default: Yes

Xcode will still generate a dSYM folder which is what you will use for symbolicating crash logs. There are 3 ways to handle symbolicating:

1. Use Xcode. For this you need to use the Product -> Archive feature whenever you release. Once an archive is created, you can select "Export" then "Save for iOS App Store Deployment". After this you can drag crash logs into the left side of the "Device Logs" window and Xcode will symbolicate them for you.

2. Manually symbolicate using the symbolicatecrash tool located inside your Xcode.app folder. This is useful if you've released code to users but don't have an Xcode archive. You need to be sure that the crash log matches the binary and dSYM or it will not work.

3. Use a third party tool that collects crash reports and symbolicates them for you. Examples include Crashlytics, Bugsense, or HockeyApp.
