我有一个像这样实现public protocol UseCase {
associatedtype ResponseType
associatedtype Parameters
func build(params: Parameters) -> Single<ResponseType>
}
public extension UseCase {
func execute(params: Parameters) -> Single<ResponseType> {
return build(params: params)
.subscribeOn(ConcurrentDispatchQueueScheduler(qos: DispatchQoS.background))
.observeOn(MainScheduler.instance)
}
}
协议的结构
UseCase我希望在另一个课程中使用此public struct CreateNewAccount: UseCase {
private let repository: AuthRepository
public init(repository: AuthRepository) {
self.repository = repository
}
public func build(params: Params) -> Single<User> {
return repository.register(params: params)
}
public struct Params: RequestParams {
...
}
}
，但我不想直接使用CreateNewAccount而我希望将其作为CreateNewAccount传递，因为因为它是一个协议它可以很容易地模拟测试。
但是当我做这样的事情时
UseCase这给了我一个像这样的错误
class RegisterViewModel: ViewModel {
private let createNewAccount: UseCase // Error on this line
init(createNewAccount: UseCase) { // Error on this line
self.createNewAccount = createNewAccount
}
}
那么，是否有一些我可以从我的代码中更改以使这种情况有效的东西？提前谢谢。
答案 0 :(得分：1)
您不能将具有关联类型的协议用作字段。
您必须仅将它们用作类的实现。在大多数情况下，这些类应该是通用的。
例如，允许使用此代码：
require'
/Users/xxx/xxx/Rakefile:4:in等等，
<top (required)>'
/Users/xxx/.rbenv/versions/2.3.1/bin/bundle:23:in
或用其他协议以某种方式包装它。
