Pod install fails when Nitro Module is added to RN application

[akpekig]

What's happening?

Following documentation, I created a Nitro Module and added it to an RN application. Pod install fails with the following error:

[!] Unable to find a specification for `NitroModules` depended upon by `NitroExample`

You have either:
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.

The error is resolved with by removing the autolinking script and manually adding Nitro-generated files:

require "json"

package = JSON.parse(File.read(File.join(__dir__, "package.json")))

Pod::Spec.new do |s|
  s.name         = "NitroExample"
  s.version      = package["version"]
  s.summary      = package["description"]
  s.homepage     = package["homepage"]
  s.license      = package["license"]
  s.authors      = package["author"]

  s.platforms    = { :ios => min_ios_version_supported, :visionos => 1.0 }
  s.source       = { :git => "https://github.com/mrousavy/nitro.git", :tag => "#{s.version}" }

  s.source_files = [
    # Implementation (Swift)
    "ios/**/*.{swift}",
    # Autolinking/Registration (Objective-C++)
    "ios/**/*.{m,mm}",
    # Implementation (C++ objects)
    "cpp/**/*.{hpp,cpp}",
+    # Generated cross-platform specs
+    "nitrogen/generated/shared/**/*.{h,hpp,c,cpp,swift}",
+    # Generated bridges for the cross-platform specs
+    "nitrogen/generated/ios/**/*.{h,hpp,c,cpp,mm,swift}",
  ]

+  s.public_header_files = [
+    # Generated specs
+    "nitrogen/generated/shared/**/*.{h,hpp}",
+    # Swift to C++ bridging helpers
+    "nitrogen/generated/ios/NitroExample-Swift-Cxx-Bridge.hpp"
+  ]
+
+  s.private_header_files = [
+    # iOS specific specs
+    "nitrogen/generated/ios/c++/**/*.{h,hpp}",
+  ]
+
+  s.pod_target_xcconfig = {
+    # C++ compiler flags, mainly for folly.
+    "GCC_PREPROCESSOR_DEFINITIONS" => "$(inherited) FOLLY_NO_CONFIG FOLLY_CFG_NO_COROUTINES",
+    # Use C++ 20
+    "CLANG_CXX_LANGUAGE_STANDARD" => "c++20",
+    # Enables C++ <-> Swift interop (by default it's only C)
+   "SWIFT_OBJC_INTEROP_MODE" => "objcxx",
+    # Enables stricter modular headers
+    "DEFINES_MODULE" => "YES",
+  }

-  load 'nitrogen/generated/ios/NitroExample+autolinking.rb'
-  add_nitrogen_files(s)

+ s.dependency 'NitroModules'
  s.dependency 'React-jsi'
  s.dependency 'React-callinvoker'
  install_modules_dependencies(s)
end

Reproduceable Code

require "json"

package = JSON.parse(File.read(File.join(__dir__, "package.json")))

Pod::Spec.new do |s|
  s.name         = "NitroExample"
  s.version      = package["version"]
  s.summary      = package["description"]
  s.homepage     = package["homepage"]
  s.license      = package["license"]
  s.authors      = package["author"]

  s.platforms    = { :ios => min_ios_version_supported, :visionos => 1.0 }
  s.source       = { :git => "https://github.com/mrousavy/nitro.git", :tag => "#{s.version}" }

  s.source_files = [
    # Implementation (Swift)
    "ios/**/*.{swift}",
    # Autolinking/Registration (Objective-C++)
    "ios/**/*.{m,mm}",
    # Implementation (C++ objects)
    "cpp/**/*.{hpp,cpp}",
  ]

  load 'nitrogen/generated/ios/NitroExample+autolinking.rb'
  add_nitrogen_files(s)

  s.dependency 'React-jsi'
  s.dependency 'React-callinvoker'
  install_modules_dependencies(s)
end

Can you reproduce this issue in the Nitro Example app here?

I didn't try (⚠️ your issue might get ignored & closed if you don't try this)

Additional information

• I am using Expo
• I am using Nitrogen (nitro-codegen)
• I have read and followed the Troubleshooting Guide.
• I created a reproduction PR to reproduce this issue here in the nitro repo. (See Contributing for more information)
• I searched for similar issues in this repository and found none.

i'd need a repo for that to see what got generated
