RxSwift - 游乐场执行失败：无法查找符号

Question

我创建了一个新项目并使用 pods 安装了 RxSwift。然后我创建了一个游乐场并编写了以下代码：

import UIKit
import RxSwift
import PlaygroundSupport

var name = "hello"
let names = Variable(["Good"])

但控制台显示此错误：

Playground execution failed:

error: Couldn't lookup symbols: __T07RxSwift8VariableCACyxGxcfC
__T07RxSwift8VariableCMa

Answer 1

为 Podfile 试试这个：

platform :ios, '11.0'

target 'RxSwiftPlayground' do
  use_frameworks!

  # Pods for RxSwiftPlayground
  pod 'RxSwift', '~> 4.0'
end

post_install do |installer|

    installer.pods_project.build_configurations.each do |config|
        config.build_settings.delete('CODE_SIGNING_ALLOWED')
        config.build_settings.delete('CODE_SIGNING_REQUIRED')
    end

    installer.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
            config.build_settings['CONFIGURATION_BUILD_DIR'] = '$PODS_CONFIGURATION_BUILD_DIR'
        end
    end
end

或者

删除‘import RxSwift’这一行
清理 (Cmd + Shift + K)
构建（有错误）
放回“导入 RxSwift”
