I want to encapsulate some of the functionality of my app in a dynamic framework. In this framework, I want to use Realm to persist some of the data.
Naturally, the way to test frameworks is with XCTest. However, any use of Realm aside from the import statement in my XCTestCase subclasses, and I get this bizarre error:
I included Realm.framework and RealmSwift.framework in my framework using a Copy Files phase. I tried not doing that, as well. I've tried linking Realm and RealmSwift in my test target, and not linking them. I've tried everything I can think of. I don't know what's happening.
This is a framework that, at the moment, does almost nothing. There's an
Object subclass, with no properties at all, and there's a test case, which simply sets up the Realm configuration for testing, and then does nothing else:
Realm.Configuration.defaultConfiguration.inMemoryIdentifier = "TestFrameworkTests"
as recommended in the documentation.
Doing literally anything with the
Realm object, or any Realm classes, causes this weird error. And it gets a little bit weirder:

Bad file descriptor. Where is that coming from? Is this an Xcode bug? If so – has anyone found a workaround?
Here's a copy of the framework, if you want to mess around with it: https://www.dropbox.com/s/q1708dw7uuaakoo/TestFramework.zip?dl=0
