无法迁移到3.0豆荚型程序库

Question

我使用Kanna和Reachability程序库。似乎他们已经迁移到SWIFT 3.我用Cocoapods：

# Uncomment this line to define a global platform for your project 
platform :ios, '8.0' 
# Uncomment this line if you're using Swift 
use_frameworks! 

target 'MyProj' do 
pod 'Kanna', '~> 2.0.0' 
pod 'ReachabilitySwift', '~> 3' 
end 

post_install do |installer| 
installer.pods_project.targets.each do |target| 
    target.build_configurations.each do |config| 
     config.build_settings['SWIFT_VERSION'] = '3.0' 
    end 
end 

末

遇到错误时做进口：

与雨燕2.3编译

import Kanna 
import ReachabilitySwift 

模块无法在斯威夫特进口3.0

Flag：Use legacy swift versions处处设置为No
