iOS 应用程序具有神秘的 UUID，没有匹配的 dSYM，因此无法进行符号化

Question

I'm pretty familiar with how crash logs for iOS apps are symbolicated but this one is a head scratcher.

I have MyApp with build 2345 that was released as a beta through TestFlight, using the normal Archive then Upload to App Store flow in Xcode 7.2 (7C68).

When I do a dwarfdump for the binary in the the xcarchive, I get the following:

dwarfdump --uuid MyApp.app/MyApp
UUID: 0BDA6D6F-3C0D-339E-842F-C2CB04199E10 (armv7) MyApp.app/MyApp
UUID: B2A69BEC-DF5E-33EA-A9E0-490EBF03074C (arm64) MyApp.app/MyApp

Here is the dwarfdump for the dSYM file:

dwarfdump --uuid MyApp.app.dSYM
UUID: 0BDA6D6F-3C0D-339E-842F-C2CB04199E10 (armv7) MyApp.app.dSYM/Contents/Resources/DWARF/MyApp
UUID: B2A69BEC-DF5E-33EA-A9E0-490EBF03074C (arm64) MyApp.app.dSYM/Contents/Resources/DWARF/MyApp

So far, so good.

However, I received a crash through Organize > Crashes for build 2345 that has a different UUID for the binary:

0x100054000 - 0x1000fffff myapp arm64  <3715db2438743cf5aac1742d9a214c2c> /var/mobile/Containers/Bundle/Application/7313BC02-3F90-4F94-82E2-CBDC941E5D68/MyApp.app/myapp
0x100144000 - 0x1001e7fff AWSCore arm64  <c2aa13236d0437b98194c0487db69e68> /var/mobile/Containers/Bundle/Application/7313BC02-3F90-4F94-82E2-CBDC941E5D68/blink.app/Frameworks/AWSCore.framework/AWSCore
....

I know for sure that the crash report is for the same build, yet the UUID here is 3715db2... when I am expecting it to be b2a69bec...

I do have bitcode enabled so I tried doing a Download dSYMs from the Organizer Archive page (even though I built arm64 so Apple shouldn't have had to) and it retrieved dSYMs for the other UUIDs/binaries in the crash report but nothing for the myapp binary. In fact, the myapp binary is the only binary that didn't get a corresponding dSYM downloaded!

So a couple questions:

1. Where did the 3715db2438743cf5aac1742d9a214c2c version of the myapp binary come from?
2. How can I get the dSYM for it so that I can symbolicate the crash? Apple is not returning it with the "Download dSYMs" option in Xcode.

Answer 1

Looks like I found the solution.

It's possible in case you set Bitcode enabled. To get necessary dSym you should either use "Download dSYMs..." button (Xcode / Organizer / Your Archive - right panel with archive information) or download them from iTunes Connect (Activity tab, link in build's details ).

Last option helped in my situation.

Answer 2

2. dSYM stored inside your .xcarchive Right click on archive in organiser then show package content. It should be there.
