I have a third-party SDK that only includes ARM support. I can optionally link to it and it runs fine on iOS Devices. But I've lost the simulator. How can I make iOSDevice builds link to it and the Simulator builds not?

We're developing an app where the user can use one or both of the AirPods. Is there are a way to tell if the user has left, right, or both in their ears?

My iOS app creates files that I'm storing in iCloud. I've created the container, and am writing files with the ubiquity URL. It appears to be working..... except...The files are not showing in the iOS Files app, nor are they in the iCloud drive on my Mac. Any tips or example code for this? I went through the YouTube video "Supporting the Files App in iOS 11 using Swift" The code is on GitHub. It compiles and runs fine, but the files do not appear in Files.app. I'm expecting to find another layer of security or something I need to do to make this work with iOS 14.
