After changing my apps name according to How to change the name of an iOS app? Cavier Cadiz answer everything was great. When I tried to update to the latest swift version I got the error below in the tests supporting file.
import XCTest
@testable import NewAppName ! No such module "NewAppName"
The app before the name changing updates to latest swift version without any problems. Anybody knows what I might did wrong while renaming the app? How can I fix it?
