Linker errors and endless indexing

[arsnyan]

Hi!

I'm trying to start using SQLiteData in a freshly made project and I can't run tests and sometimes (seemingly) the app crashes right after launching on a simulator.
These are the errors that show when I try to run a test suite:

The suit itself doesn't seem to matter. This is my project settings for testing target:

SQLiteDataTestSupport is also in the "Link binary with libraries" under Build Phases.

For my app target, just yesterday my app crashed when I ran it with this in logs:

Today it's not crashing (which is weird cause I didn't change a thing), but it logs this:

objc[56473]: Class _TtC14IssueReporting15FailureObserver is implemented in both /Users/arsnyan/Library/Developer/Xcode/DerivedData/Quoteful-gustuuwnbamfhhdrmsxmfrpocaba/Build/Products/Debug-iphonesimulator/PackageFrameworks/IssueReporting.framework/IssueReporting (0x10586cb70) and /Users/arsnyan/Library/Developer/CoreSimulator/Devices/3148995A-E596-4BBA-A272-AD826C17F4FF/data/Containers/Bundle/Application/2236F87E-2F1F-41DC-A1C9-EF5E0A9B54A8/Quoteful.app/Quoteful.debug.dylib (0x1078bc6f0). This may cause spurious casting failures and mysterious crashes. One of the duplicates must be removed or renamed.

And here's a screenshot of app target settings:

As you can see, it's indexing (processing files) and it's been this way for more than an two hours on my MBP M4 Pro 24 GB machine just yesterday.

Here's what I tried for my Test target:

1. Added some other dependencies like swift-dependencies, swift-concurrency-extras, swift-clocks etc — didn't seem to change anything
2. Added SQLiteData (both with SQLiteDataTestSupport and with it removed) to Test target — didn't change anything. It did add an empty group to my Xcode project called "Frameworks", but it's not visible in Finder and it's empty

For the app target I did try to clean my DerivedData folder, but I did it multiple times and today I haven't done anything. It just worked all of a sudden, although logs state that there's a duplicate and it makes me think the issue is still there, it just that right now it happened to load the correct version.

Any help will be appreciated, honestly I don't understand anything in the logs and in the error tab.

Hi @arsnyan, I'm not able to reproduce crashing of the app when using SQLiteData, so if you can provide a project that demonstrates that we will happily look into it.

The linking problems you are seeing when building for tests is unfortunately a longstanding issue in Xcode where one cannot link to both a library (e.g. SQLiteData) and its test support library (e.g. SQLiteDataTestSupport). It should work just fine in an SPM package though. We should probably write some docs about this.

And then finally, as for long indexing times in Xcode. I don't think there is anything we can do in our library to remedy this. I recommend you file a feedback with Apple.

@mbrandonw, thanks for the response!

The problem with the indexing sure seems to be the issue of the Xcode, cause when I removed the package and reverted to not having any at all, the issue persisted.

I reverted back to SQLiteData in my project, here's the link to branch with it.
What seems to be interesting is that the main branch seem to run just fine (main App target) on the simulator, which I think might suggest that the issue is also with swift-dependencies or with my use of the libraries.
The Test target still seems to have linking issues despite not having any code, especially related to swift-dependencies or sqlite-data

As for SPM, from what I understand, SPM is built into Project's Package Dependencies tab and there is sqlite-data in my project's dependencies

However, I never used the Package.swift format of SPM. Do you mean that I have to use it instead of Package Dependencies tab? If so, should I use it with Xcode or should I develop using other IDEs so that Package.swift would be used?

P.S. I accidentally made a new comment instead of a reply

There appears to be something wrong with this project. I can't get the dependencies to resolve even in Xcode 16.4, whereas other projects I have resolve just fine. I would suggest recreating the project from scratch as it seems like something is corrupted in it.

My comment was specifically about you linking SQLiteDataTestSupport to your test target. You cannot do that in Xcode. But also, do you really need that linked? If you aren't using the tools in that library then you can remove that dependency from your test target.
