I create a basic test case, I cannot instantiate the variable. And while test is running, it always crashes.
import Foundation
import XCTest
import Quick
import Nimble
import UIKit
@testable import tar22102
class ViewControllerTests: QuickSpec {
override func spec() {
var vc: ViewController?
beforeEach{
vc = ViewController()
let _ = vc?.view
}
describe("testing Initial values") {
context("Reading values") {
expect(vc).toNot(beNil())
}
}
}
This is the crash log. I put breakpoint to the lines in the beforeEach, it would not reach. I also have switched to several different projects. The same issue happens.

2020-07-18 07:49:37.263912-0400 tar22102[15304:300447] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'An exception occurred when building Quick's example groups.
Some possible reasons this might happen include:
- An 'expect(...).to' expectation was evaluated outside of an 'it', 'context', or 'describe' block
- 'sharedExamples' was called twice with the same name
- 'itBehavesLike' was called with a name that is not registered as a shared example
Here's the original exception: 'NSInternalInconsistencyException', reason: 'Attempted to report a test failure to XCTest while no test case was running. The failure was:
"expected to not be nil, got <nil>
"
It occurred at: /Users/hzhan25/Desktop/DD/22102/22102Tests/_2102Tests.swift:27', userInfo: '(null)''
