# AsyncDropFirstSequence.Iterator The iterator that produces elements of the drop-first sequence. ``` struct Iterator ``` ## Topics ### Instance Methods [`func next() async rethrows -> Base.Element?`](/documentation/Swift/AsyncDropFirstSequence/Iterator/next()) Produces the next element in the drop-first sequence. [`func next(isolation: isolated (any Actor)?) async throws(AsyncDropFirstSequence.Failure) -> Base.Element?`](/documentation/Swift/AsyncDropFirstSequence/Iterator/next(isolation:)) Produces the next element in the drop-first sequence. ### Type Aliases [`typealias Element`](/documentation/Swift/AsyncDropFirstSequence/Iterator/Element) ### Default Implementations [AsyncIteratorProtocol Implementations](/documentation/Swift/AsyncDropFirstSequence/Iterator/AsyncIteratorProtocol-Implementations) ## Relationships ### Conforms To [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`Sendable`](/documentation/Swift/Sendable) [`AsyncIteratorProtocol`](/documentation/Swift/AsyncIteratorProtocol) --- Copyright © 2026 Apple Inc.
