# wait(for:)

Waits on a group of expectations.

## Declaration

```swift
func wait(for expectations: [XCTestExpectation]) -> XCTWaiter.Result
```

## Parameters

- `expectations`: An array of expectations the test must satisfy.

## Return Value

Return Value A value describing the outcome of waiting for expectations.

## Discussion

Discussion The following example demonstrates how to wait on exceptions: - (void)testSprockets {     // The test allows 60 seconds total for execution.     self.executionTimeAllowance = 60;

MySprocket *sprocket = [[MySprocket alloc] init];

XCTestExpectation *sprocketLoaded = [self expectationWithDescription:@"sprocket loaded"];     [sprocket loadUsingBlock:^(NSUInteger toothCount) {         if (toothCount == 6) {             [sprocketLoaded fulfill];         }     }];     [self waitForExpectations:@[sprocketLoaded]];

id orbitWobbled = [self keyValueObservingExpectationForObject:sprocket                                                           keyPath:@"orbitAngle.doubleValue"                                                     expectedValue:@90.0];     dispatch_async(myQueue, ^ {         [sprocket wobbleOrbit];     });     [self waitForExpectations:@[orbitWobbled]]; } Expectations can only appear in the array once. The call may return before the timeout if the test fulfills all the expectations you provide. In Objective-C code, you might use an expectation to wait on a call to an interface that uses a completion handler to return a result. From Swift code, consider calling withCheckedContinuation(function:_:) to use Concurrency instead of an expectation to wait on the result of a completion handler.
