CocoaPods: Swift语言下不更新某个库, 并指定Sw

指定编译版本

指定Target的 Swift 编译版本为 3.3

post_install do |installer|
    # Your list of targets here.
    myTargets = ['Starscream']
    
    installer.pods_project.targets.each do |target|
        if myTargets.include? target.name
            target.build_configurations.each do |config|
                config.build_settings['SWIFT_VERSION'] = '3.3'
            end
        end
    end
end

但如果是 Objective-C 跟 Swift 混编的项目, 想要引入 OC 的第三方库的话, 还需要添加另一项参数

configuration.build_settings['ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES'] = 'NO'

当项目target比较多的时候应写在最外面
举个🌰:

# Uncomment the next line to define a global platform for your project
platform :ios, '9.0'

def ntt_rd_pods
    # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
    use_frameworks!
    
    pod 'Starscream', '2.0.4'
end

target 'ntt-rd-showcase' do
    ntt_rd_pods
end

target 'ntt-rd-release' do
    ntt_rd_pods
end

post_install do |installer|
    # Your list of targets here.
    myTargets = ['Starscream']
    
    installer.pods_project.targets.each do |target|
        if myTargets.include? target.name
            target.build_configurations.each do |config|
                config.build_settings['SWIFT_VERSION'] = '3.3'
            end
        end
    end
end

注: Xcode版本9.4, Swift语言4.1, 但是Starscream是3.3, 所以写了这段代码, 能避免在合并代码的时候每次都要去更改Swift的语言版本, 好像还会影响lib的语言环境, 就是很麻烦, 这样写了之后省心了. 类似的库比较多的话就在 myTargets里面加就好了

    myTargets = ['Starscream', 'Starscream']
