# wait(for:timeout:) Creates a waiter that waits on a group of expectations for up to the specified timeout. ``` class func wait(for expectations: [XCTestExpectation], timeout seconds: TimeInterval) -> XCTWaiter.Result ``` ## Parameters `expectations` An array of expectations the test must satisfy. `seconds` The time, in seconds, the test allows for the fulfillment of the expectations. The default timeout allows the test to run until it reaches its execution time allowance. ## Return Value A value describing the outcome of waiting for `expectations`. ## Discussion Expectations can only appear in the array once. The test discards the waiter when the wait completes. 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 instead of an expectation to wait on the result of a completion handler. --- Copyright © 2026 Apple Inc.
