Debugging no longer possible after installing Custom SQLite build

What did you do?

Installed Custom SQL Build as per the instructions in the docs.

What did you expect to happen?

po command while stopping at a breakpoint while debugging in Xcode would work as per usual.

What happened instead?

po {some variable} command throws the following error (where {some variable} is any variable within the active stack frame):

error: /Users/.../MyApp-dwgxauhihhscsgfuakjstodrcfim/Build/Products/Dev-iphoneos/GRDB.framework/Headers/sqlite3.h:7281:9: error: 'sqlite3_module::xIntegrity' from module 'GRDB.sqlite3' is not present in definition of 'struct sqlite3_module' provided earlier
  int (*xIntegrity)(sqlite3_vtab *pVTab, const char *zSchema,

Environment

GRDB flavor(s): Custom SQLite build
GRDB version: 6.23.0
Installation method: (CocoaPods, SPM, manual?)
Xcode version: 15.1
Swift version: Latest (Swift 5 specified in Xcode, presumably v5.9)
Platform(s) running GRDB: iOS
macOS version running Xcode: Sonoma (14.1.2)

Demo Project

N/A

Notes

Any idea what might be causing this?
The severity is really high as it has prevented us from seeing any values while debugging so it is a major developer workflow handicap that we need to get past.

One culprit I was thinking about is that our 'Debug' build configuration is called 'Dev' for us, so within /DerivedData/MyApp-XXXXX/Build/Products the Custom SQLite build exports its build artifacts into a Debug-iphoneos folder (containing libsqlitecustom.a and the GRDB.framework folder) which we then manually copy over into our Dev-iphoneos folder). Not sure if this build config however affects GRDB / the SQLLite lib in some way?

Hello @marchy,

This looks very painful indeed. Now, I have no idea of the cause. I could use successfully use po while running the custom SQLite test app.

I recommend checking your various hypothesis. I fully understand that such build issues are delicate and time consuming... Filing a report on https://feedbackassistant.apple.com might help as well.

The error says:

error: 'sqlite3_module::xIntegrity' from module 'GRDB.sqlite3' is not present in definition of 'struct sqlite3_module' provided earlier"

This xIntegrity field was added to the sqlite3_module struct with SQLite 3.44.0 (see line 7281 of sqlite/src/sqlite.h.in in swiftlyfalling/SQLiteLib@57a280b).

So it looks like LLDB is not up-to-date. You may have stale information somewhere. I recommended performing all usual cleanup operations, because one of them may fix your issue:

  • Xcode > Project > Clean Build Folder…
  • Delete ~/Library/Developer/Xcode/DerivedData/MyApp
  • Delete MyApp.xcworkspace/xcuserdata
  • Delete MyApp.xcodeproj/xcuserdata

No news is good news. I'm closing this issue.
