ASC Doesn't generate DSYM file

The latest build of my iOS app in TestFlight does not show a "Download DSYM" link in the build metadata tab. When I uploaded the build to App Store Connect I had "enable bitcode" turned on, and I can see "Include Symbols" is set to yes in the build metadata. But no link is next to it like my other recent builds.

The last few builds I've submitted in the same manner have all generated the DSYM download links no problem. For some reason this particular build has not.

Has anyone else experienced this same issue? Any tips of how to fix this? I'd like to avoid submitting a new build if possible

Cheers

is there a fix available?

There’s nothing really to fix here. Lemme explain…

In general:

You are responsible for building the binary that you submit to the store.
That build process creates a .dSYM file that matches that binary.

If you’re using Xcode, both the binary and its .dSYM file end up within your Xcode archive.

Historically, Apple allowed, and in some cases required, apps to submit as bitcode. Apple then recompiled the app from that bitcode, and distributed that binary to end users.

That caused problems for symbolication because the binary being run by end users didn’t match the .dSYM file in your Xcode archive. To solve this, Apple created a mechanism for you to download a .dSYM file for the binary that Apple generated.

With Xcode 14, so about a year ago, Apple stopped doing the bitcode thing. To quote the Xcode 14 Release Notes.

Starting with Xcode 14, bitcode is no longer required for watchOS and tvOS applications, and the App Store no longer accepts bitcode submissions from Xcode 14.

So, the whole reason for downloading .dSYM files is now gone, and folks can go back to what they used to do before bitcode was a thing: Build the binary and it’s .dSYM locally and use that for symbolication.

If you have a process that relies on getting a .dSYM file from Apple, please update that process to work with your locally built file.

dSYM files finally popped up in ASC after five(!) days of waiting.

I have the same problem. Yesterday, I uploaded a new version and the DSYM file appeared without a problem. Today, I have uploaded a new version and the DSYM file does not appear.

We have the same problem, the button "Download Dsyms" in AppStore Connect is hidden for several builds of several apps

We have the same problem, Testflight says Includes Symbols: Yes, but for some reason no Download button.

Not sure if it is related, but starting a few hours ago (about 6) I have been unable to successfully upload any build, connection just times out on upload.

Yesterday I wrote to support as suggested in Apple Staff comment. Today I found desired "Download dSYMs" button inside the build that we uploaded to appstore also yesterday.

Same for me.. The link suddenly appeared days after uploading the build..

Like some others here my DSYM download link has now shown up as well. It took roughly 5-6 days to show up. I didn't upload a new build or change any configuration. The only thing I did was raise a support request a couple days ago. There is no activity on the request, so I can't confirm whether that is responsible for the link showing up, of if it was just a coincidence. So not really a proper solution or satisfying outcome as the cause and fix are still unknown. Would still like to see if anyone from Apple can chime in here and hopefully explain the issue in more detail and potential mitigations that can be taken.

I submitted a ticket to Feedback assistant, and someone replied yesterday that the issue had been resolved. I guess we'll find out on the next submission.

We are experiencing this issue in August, was this resolved?

arossini OP

Same here! No download button visible. The flag "Include symbols" says "YES". Even trying with App Store Connect API we weren't able to donwload anything as the dsymUrl returned is "None".

Can someone provide support to this? We really need that file to upload it on Firebase/Crashlytics.

It seems this issue consistently occurs if building with Xcode 14...

According to release notes of Xcode 14 "Bitcode is Deprecated."

https://developer.apple.com/documentation/xcode-release-notes/xcode-14-release-notes

Since Bitcode is not enabled anymore, I think Apple is stopped producing DSYM files for builds produced by Xcode 14.
