Hey, I am trying to add a pod dependency in my KMM project but I am getting an error when I am syncing

Executing of 'pod gen --platforms=ios --gen-directory=/Users/atripathi/<Project Root>/shared/build/cocoapods/synthetic/iosArm64 dogtag.podspec' failed with code 1 and message:
[!] Unknown command: `gen`
Did you mean: env?

cocoapods {
    frameworkName = "shared"
    pod("Connectivity")
}

I should also specify here that the first step mentioned here https://kotlinlang.org/docs/reference/native/cocoapods.html#install-the-cocoapods-dependency-manager-and-plugin is failing for me when I run the command so I used`brew install cocoapods`

my project is working fine on iOS when I remove pod() dependency. I am kind of confused here where things are going wrong

Hello, @Amritansh! As far as I can see, this is about cocoapods installation. As you have to install it before using in KMM project. Please take a look at those stackoverflow questions, which seems to be related: one, two.

@Artyom Degtyarev [JB] this solution worked for me Docker for Mac - mkmf.rb can't find header files for ruby. Thanks

Most probably, this is because

ios()

target shortcut was used. See this discussion: https://youtrack.jetbrains.com/issue/KT-42319
