What is actually happening?

When trying to start the app from Xcode on a appleTV4 via a remote debug session, the app doesn't start, it crashes. I was also able the reproduce the behavior with the appleTV simulator, but not consistent.

Log in debug window: `dyld: Library not loaded: @rpath/libswiftAVFoundation.dylib Referenced from: /var/containers/Bundle/Application/EF3FD657-E27B-4977-A079-B71F704D368D/TVGemist.app/TVGemist Reason: no suitable image found.

I can't reproduce the issue. I suspect this might be related to the NPO API's not responding, or responding with some invalid or missing JSON values. I have seen the NPO change their response a couple of times, which would break the abstraction, but I can't reproduce the issue you're describing at the moment. Is it working for you now?

[technimad]

Nope not working. I got an update of Xcode to 9.4.1 today and I was now able to create a screenshot of the error:

This happens right after the app starts, before the home screen of the app is displayed.

I am not fluent in assembly and the stack trace is pretty much non-existent. It looks like that the Swift libraries cannot be loaded, but that sounds a bit like an Apple bug to me.

I do sometimes experience a crash after the first start (which I thought might be caused by the logging framework), but the second start always works. I can't reproduce it consistently crashing all the time.

You could try clearing out your derived data and see if that helps? I use this bash method:

# clean derived data
cdd() {
    while true; do 
        if [ -d "~/Library/Developer/Xcode/DerivedData" ]; then
            rm -rf "~/Library/Developer/Xcode/DerivedData"
        else
            echo ".removed derived data"
            break
        fi
    done
}

But you could also close Xcode and run rm -rf "~/Library/Developer/Xcode/DerivedData" from Terminal. Alternatively try ⌘-shift-k within Xcode.

⌘-shift-k in Xcode fixed the issue. Thanks.

Good to hear 👍
