RxTest:体系结构x86_64和arm64的未定义符号

问题描述

我正尝试从 Raywenderlich RxSwift 本书:

I am trying to run the following test from Chapter 16: Testing with RxTest of Raywenderlich RxSwift book:

import XCTest
import RxSwift
import RxTest
@testable import Testing

class TestingViewModel : XCTestCase {

var viewModel: ViewModel!
var scheduler: ConcurrentDispatchQueueScheduler!

override func setUp() {
super.setUp()

viewModel = ViewModel()
scheduler = ConcurrentDispatchQueueScheduler(qos: .default)
}

func testColorNameIsRayWenderlichGreenWhenHexStringIs006636() {

// 1
let colorNameObservable = viewModel.colorName.asObservable().subscribeOn(scheduler)

// 2
viewModel.hexString.value = "#006636"

// 3
XCTAssertEqual("rayWenderlichGreen", try! colorNameObservable.toBlocking().first()!)
 }
}

但是我在模拟器上收到此错误:

But I get this error on the simulator:

iPhone 6s上的这个:

And This one on iPhone 6s:

在Raywenderlich的文档中不支持此问题论坛.

推荐答案

经过大量搜索，有人建议此处对于另一个类似的问题，我发现通过导入RxCocoa可以解决此错误.

After a lot of searches, As somebody suggests here for another similar issue I found that this error will be solved by importing RxCocoa.
