I’m profiling a SwiftData app in Instruments.

Most frames are symbolicated correctly but SwiftData frames appear only as addresses.

0x21ff2abd4  SwiftData
0x21ffb06c8  SwiftData
0x21ffb3064  SwiftData

while surrounding frames are symbolicated, for example:

__CFRunLoopDoObservers CoreFoundation
stepTransactionFlush AppKit
Attribute.syncMainIfReferences<A>(do:) SwiftUICore

Is this expected, or should SwiftData symbols normally be visible here?

Hi there!

That's a great insight – it seems that SwiftData is configured to strip Swift symbols by default, which would explain why you don't see any information about them.

I would appreciate if you could file a feedback for us using feedbackassistant.apple.com (or Feedback Assistant app). If you could reference FB number in this thread after filing, that would be fantastic.

Thanks,

Kacper
