If you install this lib as a pod and open it in a new Xcode (starting from 14), you'll see an error message saying that Signing for SatisMeter requires a development team. Select a development team in the Signing & Capabilities editor.
The only workaround is to add this as a framework to an existing project as described here. (The manual also uses a very old Xcode version π)
P.S. workarounds mentioned here do not work.
