dlopen() error: Library not loaded: @rpath/libswift_Concurrency.dylib about injectioniii

[johnno1962]

Sorry, I can't upload a release candidate today as @github seems to be broken. Will try again later.

[johnno1962]

Hi Paul, not sure what's happening there. I assume you tried the "Runtime Search paths" fix? If you can hang tight for a bit there is something new in the pipeline that can be worked on more easily.

[johnno1962]

In terms of an ETA, I imagine I'll be releasing the next-gen version of Injection as soon as I know it works with Xcode 16.

[johnno1962]

Hi, what version of Xcode is this? I'll look at modifying the "rpath" of the injection bundle to cater for this but in the meantime you should be able to add a Debug config "rpath" (Runpath Search Paths build setting) to your app of: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift-5.5/iphoneos.
Any chance you have a small example program that replicates this problem I can look at?

[paul-brenner]

This is on Xcode 15.4. I can confirm that adding the Debug config rpath as you suggested fixes it.

So far I'm failing to create a small example program that replicates, when I strip my app down to the bare bones I seem to be also stripping out whatever is causing the problem. Happy to try to do whatever else might help if there is anything else?

[johnno1962]

Never mind about a replicator as this is a small change. I'll push a new release candidate if you could test if later today.

[paul-brenner]

thanks! will do.

[johnno1962]

I've been able to upload the new pre-release using an old version of Safari 🤷‍♂️. When you get a chance can you try it out with your rpath override removed? https://github.com/johnno1962/InjectionIII/releases/tag/5.0.1RC1

[paul-brenner]

wow! Tested and confirmed working. Thank you!

[johnno1962]

Just a heads up that if I build on the simulator and just leave it sitting there I'll see the same errors filling up my logs:

But then as soon as I go into a file with @ObserveInjection var redraw and make changes it happily shows

💉 Compiling /Users/paul/Siv/siv-ios/Siv/Siv/Features/Main/CustomTabBar.swift
💉 Loading .dylib ...
💉 Interposed 20 function references.
💉 Injected type #1 'Siv.CustomTabBar'
💉 Injected type #2 'Siv.CustomTabItem'

then works as expected. So very much working for me, but I imagine if a new user setting up sees those messages they may not realize that everything will still work.

[johnno1962]

Yeah that's weird. Xcode autosaves files from time to time which would trigger an injection. Does it tell you what file it's recompiling? Does that make sense? I don't know what sort of file would cause the problem to come back though.

[paul-brenner]

Ah I see that Inject just conveniently told me:

💉 Compiling /Users/paul/Siv/siv-ios/Siv/Siv/Data/SivRepository.swift
💉 Loading .dylib ...

but that file is purely backend. I can put it up temporarily here if that is helpful at all.

[paul-brenner]

Not sure how much this is a problem worth fixing for everyone or just a problem unique to me but it is broken again for reasons I can't figure out:

💉 ⚠️ Clean build folder when switching platform

This is when I save a file that actually is a view and right after cleaning the build folder.

[paul-brenner]

Sounds good! I'll keep working with it and see if I can figure anything out in the mean time. Now that I've tried InjectionIII, I can't imagine going back to the old way, even with the errors I'm hitting.
