After Kotlin 1.7.0, the cocoapods-generate tool is no longer required. I still get the following:

Should this be included in the output still? It's useful information if the user is below Kotlin 1.7.0, but not useful for users using Kotlin 1.7.0 or higher.

There is a problem with system Ruby on M1 macs when someone tries to use cocoapod-generate gem. It looks like error:

  /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/rubygems/core_ext/kernel_require.rb:54:in `require': dlopen(/Library/Ruby/Gems/2.6.0/gems/ffi-1.15.5/lib/ffi_c.bundle, 0x0009): tried: '/Library/Ruby/Gems/2.6.0/gems/ffi-1.15.5/lib/ffi_c.bundle' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')) - /Library/Ruby/Gems/2.6.0/gems/ffi-1.15.5/lib/ffi_c.bundle (LoadError)

or something like this.

Work around is to use custom Ruby installation (and reinstall cocoapods and cocoapod-generate gems): https://youtrack.jetbrains.com/issue/KT-49418#focus=Comments-27-5429773.0-0

It would be better to help kdoctor users with this case

Sometimes (literally sometimes, I see no consistent pattern) when you're trying to execute some shell command using System.execute(), it returns with returnCode 65280, and error == null, output == null. Meanwhile, an execvp() documentation says that the list of arguments must be null-terminated.

Also, added shell commands logging

Open XCode > Preferences > Locations > Custom Paths and add a custom path with name JAVA_HOME pointing to my current JAVA_HOME directory.

After running kdoctor I've got this error:

[x] Cocoapods
    ruby (ruby 2.6.8p205 (2021-07-07 revision 67951) [universal.arm64e-darwin21])

    * System ruby is currently used
          Consider installing ruby via Homebrew, rvm or other package manager in case of issues with cocoapods installation

    ruby gems (3.0.3.1)

    * cocoapods not found
          Get cocoapods from https://guides.cocoapods.org/using/getting-started.html#installation

But my cocoapods is fine:

pod --version
1.11.2

My Cocoapods is installed from homebrew.

This may be a wrong error, I actually don't have pod-gen installed, because my env works fine without it - I don't use any pod dependencies from Kotlin part.

Fixes:

• Fixed the case when LC_CTYPE env var is empty but there is still a value in locale settings
• Use -version instead --version for getting java version cause the last is not supported by JAVA 8
• Filter off Toolbox backup versions of Android Studio

1. System.execute: redirect stderr of a child process to a separate pipe to avoid mixing of output streams. For example, gem -- version prints valid version and some warning to stderr

gem --version
Ignoring ffi-1.15.0 because its extensions are not built. Try: gem pristine ffi --version 1.15.0
3.0.3.1

2. System method for file reading: extract common logic to private functions

Various bug fix:

1. Apple chips support for System Diagnostics
2. Search Android Studio in Jetbrains Toolbox default folder
3. Additional notes regarding Xcode and Android Studio using different Java environments by default

~/.konan directory contains all Kotlin/Native compilers and their dependencies. This directory tends to grow to tens of gigabytes (47gb on my machine, though I'm kinda an edge case 🌝). It would be nice to have a CLI option that just removes this directory altogether, so that only relevant artifacts will be downloaded when user starts to work on their project.

Hello friends!

First of all - thank you for building this tool for KMM development! I was excited when I saw it mentioned in the Kotlin blog a little while back, as I've been using KMM for the last couple of years. 😃

I am curious about how you envision this tool evolving in the future.

The most challenging aspect of KMM development that I have found is managing and maintaining the Gradle configuration for the shared modules using Gradle. As KMM has evolved and the Gradle configuration needs to change, it has been challenging for me to determine the proper Gradle configuration for all components to work together harmoniously. Once it's working, I tend to try not to touch it as I perceive it to be quite brittle, and even still sometimes IntelliJ will indicate issues with the configuration even though it appears to be working to me. My "Gradle-fu" is admittedly relatively limited, and I desire to focus on the development of the product and not get lost in configuration details, so these are likely contributing factors.

Specifically, I'm referring to the build.gradle.kts (or build.gradle) file for any shared module. This includes the configuration of the targets (Android, iOS, or otherwise), Android-specific configuration, and the configuration for building the framework to be used with iOS (including Debug/Release/Custom build configurations, managing architectural differences such as simulator vs. device, etc.).

If this is a part of your vision for this product, then I'd be willing to get involved in some conversations about how I might be able to contribute to this somehow. If this isn't a part of your vision - no worries at all, and maybe I can look to find a better place to share this feedback. I just thought it might be worth asking here to see. 👍🏻

Thanks for your kind consideration! 🙇🏻‍♂️

Please check the output for problem description and possible solutions.

While I happen to have Cocoapods installed (via Homebrew) for some other Xcode projects, based on personal preference for my own projects, I do not use Cocoapods. Therefore, receiving information regarding how cocoapods is not configured properly for me is irrelevant.

I'm not sure if there are other developers who are similar to me, however, if there are, then I would suggest it might be helpful to make the Cocoapods confirmation optional as it is not required for KMM (or iOS) development, or change the verification result from "error" to warning with a stipulation that it is only important if you are actively using Cocoapods.
