This app could not be installed at this time.

First of all, thank you so much for sharing your efforts!

I followed the tutorial, and change the build settings Skip Install to 'NO' everywhere. Everything compiles fine, no errors. But when I try to run in the simulator (as series 2 or 3) I get the same error:

I googled the message but have been unable to determine what the problem is (I even went through the log directories and scanned the error/system logs but still didn't find a reason for the error. I cleaned, deleted the app off the simulator, rebooted, etc. multiple times, but I still get that message. Has anyone seen and solved this issue before?

Thanks.

Try clearing your build cache by going to Product/Clean in Xcode

Although I had done that, I tried it again. But when I went back (it's been just about a month) I found that the gambatte framework no longer compiled cleanly (it had about 38 errors, which fluctuated as I fixed the code).
I found this link you provided and followed all the steps: pull request
And got the framework to compile cleanly. But I still get the same message: "This app could not be installed at this time."
Has anyone gotten it to install using Xcode 9.3? I'm running macOS High Sierra version: 10.13.4 (17E202)
Thanks.
