# Publishers.Merge6 A publisher created by applying the merge function to six upstream publishers. ``` struct Merge6 where A : Publisher, B : Publisher, C : Publisher, D : Publisher, E : Publisher, F : Publisher, A.Failure == B.Failure, A.Output == B.Output, B.Failure == C.Failure, B.Output == C.Output, C.Failure == D.Failure, C.Output == D.Output, D.Failure == E.Failure, D.Output == E.Output, E.Failure == F.Failure, E.Output == F.Output ``` ## Topics ### Creating a merge-six publisher [`init(A, B, C, D, E, F)`](/documentation/Combine/Publishers/Merge6/init(_:_:_:_:_:_:)) publisher created by applying the merge function to six upstream publishers. ### Merging elements [`func merge

(with: P) -> Publishers.Merge7`](/documentation/Combine/Publishers/Merge6/merge(with:)) [`func merge(with: Z, Y) -> Publishers.Merge8`](/documentation/Combine/Publishers/Merge6/merge(with:_:)) ### Declaring supporting types [`typealias Output`](/documentation/Combine/Publishers/Merge6/Output) The kind of values published by this publisher. [`typealias Failure`](/documentation/Combine/Publishers/Merge6/Failure) The kind of errors this publisher might publish. ### Inspecting publisher properties [`let a: A`](/documentation/Combine/Publishers/Merge6/a) A publisher to merge. [`let b: B`](/documentation/Combine/Publishers/Merge6/b) A second publisher to merge. [`let c: C`](/documentation/Combine/Publishers/Merge6/c) A third publisher to merge. [`let d: D`](/documentation/Combine/Publishers/Merge6/d) A fourth publisher to merge. [`let e: E`](/documentation/Combine/Publishers/Merge6/e) A fifth publisher to merge. [`let f: F`](/documentation/Combine/Publishers/Merge6/f) A sixth publisher to merge. ### Comparing publishers [`static func == (Publishers.Merge6, Publishers.Merge6) -> Bool`](/documentation/Combine/Publishers/Merge6/==(_:_:)) Returns a Boolean value that indicates whether two publishers are equivalent. ### Default Implementations [Equatable Implementations](/documentation/Combine/Publishers/Merge6/Equatable-Implementations) ## Relationships ### Conforms To [`Equatable`](/documentation/Swift/Equatable) [`Publisher`](/documentation/Combine/Publisher) --- Copyright © 2026 Apple Inc.
