在RxSwift中的combineLatest中，无法使用类型为“”(@escaping (_) -> _)“”的参数列表调用“filter”

Question

我试图从我试图合并的两个流中过滤出一些东西。我尝试的这两个值是同一类型的，所以我似乎不能理解为什么我会遇到这个问题。

 let currentUserEmail = Observable.just(currentUserEmail)
            .unwrap()

//使用一些内部方式获取邮箱的访问权限

let listOfAllUsers = Observable.combineLatest(getUsersList(), currentUserEmail) { allUsers, currentUserEmailAddress in
        return allUsers.filter { $0.emailAddress != currentUserEmailAddress } }
    .asObservable()
    .share(replay: 1, scope: .whileConnected)

Answer 1

let currentUserEmail = currentUserEmail

let listOfAllUsers = getUsersList()
       .asObservable()
       .share(replay: 1, scope: .whileConnected)

let newListOfAllUsersWithoutCurrentUser = listOfAllUsers.map { allUsers in
             allUsers.filter { $0.emailAddress != currentUserEmail }
         }
         .share(replay: 1, scope: .whileConnected)

这对我来说最终是有效的。
