带有Alamofire和ObjectMapper的Swift 4.0没有这样的模块'ObjectMapper'

Question

Hi I am new to IOS development. I am creating one small application. I am trying to import ObjectMapper but it gives me no module found. I already did pod install. My pod file looks like :

  target 'Sample' do
# Comment the next line if you're not using Swift and don't want to use dynamic frameworks
use_frameworks!

# Pods for Sample
pod 'Alamofire', '~> 4.5.0'
pod 'AlamofireObjectMapper', '~> 5.0'
pod 'AlamofireImage', '~> 3.3'
pod 'PKHUD', '~> 5.0'
pod 'ObjectMapper', '~> 3.0.0'

end

I am using swift version 4.0.2 and Xcode version is 9.1. Is there any thing missing? Need some help.

Answer 1

ObjectMapper的最新版本是pod 'ObjectMapper', '~> 3.1' ，一件事是清理并构建您的项目，并确保您正在使用YourProjectName.xcworkspace

Answer 2

Try with version 3.4 . it works for me.

pod 'ObjectMapper', '~> 3.4'

1) Model Class One--------------
-----------------------------------------
-----------------------------------------

import Foundation
import ObjectMapper

class MainData : NSObject, Mappable {
    var page : Int?
    var per_page : Int?
    var total : Int?
    var total_pages : Int?
    var data : [Data]?
    override init() {

    }
    required init?(map: Map) {

    }

     func mapping(map: Map) {

        page <- map["page"]
        per_page <- map["per_page"]
        total <- map["total"]
        total_pages <- map["total_pages"]
        data <- map["data"]
    }

}
2) Model Class Two--------------
-----------------------------------------
-----------------------------------------

import Foundation
import ObjectMapper

class Data : NSObject, Mappable {
    var id : Int?
    var name : String?
    var year : Int?
    var color : String?
    var pantone_value : String?
    override init() {

    }
    required init?(map: Map) {

    }

     func mapping(map: Map) {

        id <- map["id"]
        name <- map["name"]
        year <- map["year"]
        color <- map["color"]
        pantone_value <- map["pantone_value"]
    }

}
