What did you do?

Created AsynchronousSpec according to example in #1217

What did you expect to happen?

Test to compile and run

What actually happened instead?

Test fails to compile with Mutation of captured var 'ocean' in concurrently-executing code

Project that demonstrates the issue

import Quick
import Nimble

class AsynchronousSpec: AsyncSpec {
    override class func spec() {
        it("runs the test in an async context") {
            var ocean: [String] = []
            DispatchQueue.main.async {
                ocean.append("dolphins")
                ocean.append("whales")
            }
            await expect(ocean).toEventually(contain("dolphins", "whales"))
        }
    }
}

Yep. That's correct. The example will have to be updated.

Edit: The example linked (and the release page) have now been updated with code that compiles.
