I would like to create a library for iOS applications which uses UIKit. Furthermore I would like to create unit tests for this library. Unfortunately my tests do not work because of UIKit ([UIFont systemFontOfSize:12.0] to be precise).
According to Apple's Unit Testing Guide there are two types of test cases: logic tests and application tests. Application tests seem to be the correct type for tests involving UIKit related stuff but I did not find out about how to set up application tests for libraries. Has anybody ever had the same problem and was able to solve it?
Thanks a lot!

Overview. The UIKit framework provides the required infrastructure for your iOS or tvOS apps.
If you have only a Package. swift , you can build and test via xcodebuild similar to how you would with a Xcode project. First, run xcodebuild -list to find valid schemes from the package. Then invoke xcodebuild with the desired scheme.
Recording a UI TestFrom the debug bar, click the Record UI Test button. Xcode will launch the app and run it. You can interact with the element on-screen and perform a sequence of interactions for any UI test. Whenever you interact with an element, Xcode writes the corresponding code for it into your method.
I found a solution to this. You must add a new target to your project that is simply an empty application. Then use that application as your test host following the instructions for doing this with a regular application like here:
Why does instantiating a UIFont in an iphone unit test cause a crash?
