Great Video. I'm trying to use the `TestObserver` in my own tests outside of a playground. How would you use the custom `TestObserver` in a unit test target outside of a playground?
I've tried the following, but I'm not getting the expected messages with the colored emojis. What am I doing wrong?
```
import XCTest
@testable import MyApp
class TestObserver : NSObject, XCTestObservation {
func testCase(_ testCase: XCTestCase, didFailWithDescription description: String, inFile filePath: String?, atLine lineNumber: Int) {
print("🚫 \(description) line:\(lineNumber)")
}
func testCaseDidFinish(_ testCase: XCTestCase) {
if testCase.testRun?.hasSucceeded == true {
print("✅ \(testCase)")
}
}
}
let observer = TestObserver()
let x = XCTestObservationCenter.shared.addTestObserver(observer)
class MyTest: XCTestCase {
...
```
