No code signature found.

Hi, I am a new Apple developer. I have been using Unity to create an iOS app. We have successfully been uploading the builds to TestFlight, and we are able to run the app on all of our devices through that.

The problem is that I would like to install the app directly to my iPhone and that is telling me "No code signature found."

In Xcode, I have tried to install it with "automatically manage signing" on and off. There are no issues shown for the provisioning profile. I tried using a certificate signing request, and I'm not completely sure if that was done correctly. I have a single certificate in my name of type development and two others for the team of type distribution and distribution managed. Do I need one in my name of type distribution?

We have had an issue that we could solve much more easily if we could do quicker tests like this, so any help would be appreciated.

As a first step, use Xcode to create a small test project from the iOS > App template. Build that, and then run it on your device. If that works, you know that:

  • Your code signing is generally set up OK.

  • Your problem is specific to your third-party tools.

In that case my recommendation is that you escalate this via the support channel for those tools, because you’re more likely to connect with folks who have relevant experience over there.

OTOH, if you can’t get a trivial Xcode project working then I’m happy to help with that.

I didn't mean to mark that as correct. I did what you said and the test project was successfully installed on my device. Can you tell me what you mean by tools? I have several packages that I imported into the Unity Project. Do you mean those tools or Unity itself? Or do you mean something completely different? Thank you for the reply.

Do you mean those tools or Unity itself?

The latter.
