我是swift软件包的新手，我试图创建一个简单的函数来授权用户，但是Xcode似乎找不到我的"ApiCalls"结构，尽管我已经将所有内容设置为公共，并且我遵循了如何制作软件包的教程。我一直收到这个错误

这是我的包裹

我哪里做错了？
我试着查找这个，主要问题是我的结构体和变量没有设置为public，但是即使修改Xcode也找不到它。
更新：我将其设置为静态，但仍然收到相同的错误消息：

public struct ApiCalls {
public init(currentAPIDomain: String = "my.url") {
    ApiCalls.currentAPIDomain = currentAPIDomain
}

public static var currentAPIDomain : String = "https://castle-learning-1541513232785.appspot.com/"

public static func RestApiRequest<T:Decodable>(method:ApiCallsRequestMethods, endpoint: String, model: T.Type, requirements: ApiCallsRequestRequirements) async throws -> T {
    
    guard var endpointURL = URL(string: currentAPIDomain + endpoint) else { throw ApiCallErrors.DomainMalformed }
    
    if requirements.subtitles != nil && requirements.subtitles == true {
        endpointURL = URL(string: endpoint)!
    }
    var request = URLRequest(url: endpointURL)
    
    switch method {
    case .GET:
        request.httpMethod = "GET"
    case .POST:
        request.httpMethod = "POST"
    case .PUT:
        request.httpMethod = "PUT"
    case .DELETE:
        request.httpMethod = "DELETE"
    }
    
    if requirements.subtitles != nil && requirements.subtitles == true {
        request.addValue("fdD7F8Orql9WBolf9BgjrYIDFcFhH9Hz", forHTTPHeaderField: "Api-Key")
    }
    
    if Array(requirements.token.keys)[0] == true {
        request.addValue("Bearer \(requirements.token[true]!)", forHTTPHeaderField: "Authorization")
    }
    
    if Array(requirements.body.keys)[0] == true {
        let body: [String:Any] = requirements.body[true]!
        let finalBody = try! JSONSerialization.data(withJSONObject: body)
        request.httpBody = finalBody
    }
    
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    
    guard let (data, response) = try? await URLSession.shared.data(for: request) else {
        throw ApiCallErrors.InvalidData
    }
    guard (response as? HTTPURLResponse)?.statusCode == 200 else { throw ApiCallErrors.Unexpected }
    
    guard let decodedData = try? JSONDecoder().decode(T.self, from: data) else {
        throw ApiCallErrors.ErrorDecoding
    }
    
    return decodedData
}

public static func login(username: String, password: String) async throws -> String {
    do {
        let results = try await RestApiRequest(method: .GET, endpoint: "ptv/login", model: Login_SignUp_Model.self, requirements: ApiCallsRequestRequirements(token: [false : ""], body: [true : ["email" : username, "password":password]]))
        return results.message
    } catch {
        throw error
    }
}
