Answer 1

在您的构建设置中转到此处...

然后突出显示“始终嵌入...”行并点击删除。这会将其更改为使用继承的属性。

即使您进行了此更改，它仍会保留在那里，但它可能会从粗体变为普通文本。如果发生这种变化，那么它就会被继承。

普通文本 = 继承。

粗体字 = 被覆盖。

Answer 2

1. 删除您的 Pods 文件夹
2. 将 ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES 设置为 $(inherited)；
3. 运行 pod 安装

Answer 3

公认的解决方案有效，但现在您必须确保所有队友都在执行它pod install。

我们都知道他们不会。

您可以让 CococaPods 自动执行此操作，方法是将其添加到 Podfile 的底部：

post_install do |installer_representation|
    installer_representation.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
            if config.name == 'MyPOD' 
                config.build_settings['ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES'] = 'Yes'
            end
        end
    end
end

1. 转到构建设置

Answer 5

我建议按照消息中的建议在安装后设置所有 pod：

post_install do |installer_representation|
    installer_representation.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
            config.build_settings['ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES'] = '$(inherited)'
        end
    end
end
