Testing Async Code

Verify async/await flows reliably.

Async Needs Special Care

Network calls and tasks finish later, not instantly. Your tests must wait for the result before asserting, or they check too early. ⏳

Mark the Test async

The simplest fix is an async test method. Swift lets you await directly, and the runner pauses until the work completes.

func testLoad() async {
}
