Adding a framework to a test target
I wanted to add the AnyCodable to both my iOS project, and the test project that tests it.
When I added it to just my iOS project I got the error Undefined symbol: nominal type descriptor for AnyCodable.AnyCodable
when trying to run tests.
My solution was to remove the framework, and then re-add it, this time specifying the test target as the target into which the framework should be added.
Once I did that, I was then
able to go to my iOS project’s target, and in the General
pane, scroll down to Frameworks, Libraries, and Embedded Content
and add it there.
