Getting error `Library not loaded` etrace

[msdrigg]

I added ETrace via SPM to my iOS (swift-only) app in XCode. Now when I run my app, it fails to boot with this error:

dyld[5492]: Library not loaded: @rpath/ETTrace.framework/ETTrace

Things I've tried:

• Making sure I have set "ETrace to 'Embed & Sign'
• Playing around with "Destination" in Build Phases -> Embed Frameworks (I tried "Frameworks", "Shared Frameworks" and "Products Directory"

Here are screenshots of the relevant sections:

The weirdest thing is that if I look in /Users/me/Library/Developer/Xcode/DerivedData/App-cklguuvlmfepaxaevnzjgkgtwzmc/Build/Products/Debug-iphoneos/PackageFrameworks/ETTrace.framework/ETTrace (the first path that it says it tried), I can see that ETTrace actually does exist.

Hey @msdrigg the framework should be in your apps framework folder to be used, so MyApp.app/Frameworks, it looks like it's in a different path based on your description so please make sure your Xcode settings have it copied into the app's frameworks folder

[noahsmartin]

Also ETTrace is a dynamic framework not static, yet in the screenshots you posted the icon Xcode displays is an icon for a static framework

Any pointers as to what I should google to figure out how to change the right configuration parameters?

I tried googling the error with no helpful results

[noahsmartin]

@msdrigg maybe a delete derived data and restart Xcode? When I add the target to my app I only see the dynamic framework option, in the Package.swift we only have the product be a dynamic framework:

    products: [
        .library(
            name: "ETTrace",
            type: .dynamic,
            targets: ["ETTrace"]
        ),

Hmm I tried that and still seeing the same icon. Could it be an XCode 15.3 thing? I only started this app a few months ago and have the xcode package format updated to the latest.

This should be reproducible here https://github.com/msdrigg/Roam/tree/ETTRace

Hey @msdrigg sorry for the delay here, are you still seeing it? I can't access the example GitHub project

Oh dang I forgot this was still relevant and I deleted that branch. This issue was never resolved, but I ended up debugging my issue with apple's instruments instead.
