How to update a cocoapod built in Swift 3 to Swift 4

So I've downloaded the Xcode 9 beta, and I've been tasked with updating one of our in house pods from Swift 3 to Swift 4. I have cloned the repo, and opened it and can see all the project files and everything else, but there is no scheme, and I am unable to use Edit > Convert > Convert to current Swift syntax as it is greyed out.

On the main project, I used the migration tool and then went through manually and added @objc to expose whatever was referenced in Objective-C, but I can't seem to be able to do that with the pod.

I'm just wondering if someone has any experience on updating a pod to Swift 4, and if so how do I go about doing it as there is very little information online about it.

Many thanks as always,

Niall

The best way to do this is with a post install hook in your pod file. Otherwise each time you install/update your pods that setting will be changed back

source 'https://github.com/CocoaPods/Specs.git'
use_frameworks!

target 'ProjectX' do
    pod '_your_pod_'
end

post_install do |installer|
    installer.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
            config.build_settings['SWIFT_VERSION'] = '3.2'
        end 
    end
end

Go to your Pods project, then:

  1. Select the target you want to update
  2. Go into its build settings
  3. Select Swift 3.2 as the language version

You can try to change pod language swift4.0 to swift3.2 . It might solve your problem. It can be done in build settings. Search swift and change it.
