ios - 更新 swift 版本和 pod 后的链接器错误

Question

我正在使用 pod 安装 Alamofire 并遇到编译时错误。对此有很多问题，但是:

删除派生数据和更新 pod 对我不起作用。

这是错误:

Alamofire/Alamofire.framework/Alamofire compiled with newer version of Swift language (3.0) than previous files (2.0) for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

Answer 1

更新 pod 文件中的以下内容:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.0'
use_frameworks!

post_install do |installer|
    installer.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
            config.build_settings['SWIFT_VERSION'] = '2.3' || '3.0'
            config.build_settings['ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES'] = 'NO'
        end
    end
end
