Generating Cocoapods Module Error [ARC] xcodebuild: Bad exit code returned

I am starting to quietly do iOS development, this is my first question on SO. At my company, we are trying to convert our application to a Cocoapods module to help build different applications with similar functionality. So far we have tried to compile the POD module, but when we try to import classes from the module in the workspace. An example is attached, we get "Failed to create module ProjectCore"

#import <ProjectCore/myProjectCoreClass.h>

      

        
        
        
      

    

It is not possible to get more information about where the building is not working. Am I missing something? Is there a way to find out where the build process is happening?

Thank.

After carefully checking the manual and trying to check the pile for the building:

pod lib lint --verbose --allow-warnings

      

        
        
        
      

    

My project only uses ARC in some modules, so the podspec looks like this.

Pod::Spec.new do |s|
s.name             = 'ProjectCore'
s.version          = '0.1.3'
s.summary          = 'A short description of ProjectCore.'


s.description      = 'This is our core a git with cocoapods - ProjectCore.'

s.homepage         = 'https://bitbucket.org/projectcore/ios_projectcore'
s.license          = { :type => 'MIT', :file => 'LICENSE' }
s.author           = { 'Comapny' => 'info@company.com' }
s.source           = { :git => 'https://bitbucket.org/projectcore/ios_projectcore.git', :tag => s.version.to_s }

s.ios.deployment_target = '9.0'


s.frameworks = 'CoreData', 'SystemConfiguration', 'Accelerate', 'CoreGraphics', 'CoreLocation', 'CoreText', 'GLKit', 'ImageIO', 'OpenGLES', 'QuartzCore', 'UIKit', 'AdSupport', "GoogleMapsCore", "GoogleMapsBase", "GoogleMaps", "Crashlytics", "Fabric"
s.library = 'z', 'c++', 'xml2'
s.vendored_frameworks   = "StaticLibraries/GoogleMapsServices/GoogleMaps.framework", "StaticLibraries/GoogleMapsServices/GoogleMapsBase.framework", "StaticLibraries/GoogleMapsServices/GoogleMapsCore.framework", 'StaticLibraries/FabricCrashlytics/Crashlytics.framework', 'StaticLibraries/FabricCrashlytics/Fabric.framework'
s.vendored_libraries = 'StaticLibraries/GoogleAnalyticsServices/*.a', 'StaticLibraries/GoogleConversionTracking/*.a'
s.xcconfig = {'OTHER_LDFLAGS' => '-ObjC', 'CLANG_ALLOW_NON_MODULAR_INCLUDES_IN_FRAMEWORK_MODULES' => 'YES', 'HEADER_SEARCH_PATHS' => '$(SDKROOT)/usr/include/libxml2'}


arc_files = 'ProjectCore/**/ActionMenuHelper.{h,m}',
'ProjectCore/**/UnitsFormatter.{h,m}',
'ProjectCore/**/BSKeyboardControls/**/*.{h,m}',
'ProjectCore/**/CellMenuLeft.{h,m}',
'ProjectCore/**/CheckInternetConnection.{h,m}',
(...)

s.requires_arc = false
s.source_files = 'ProjectCore/**/*.{h,m,swift}','StaticLibraries/GoogleAnalyticsServices/*.h','StaticLibraries/GoogleConversionTracking/**/*.h','StaticLibraries/ZLib/*.h','StaticLibraries/XMLParser/*.h'

s.exclude_files = arc_files
s.subspec 'ARC' do |sp|
sp.requires_arc = true
sp.source_files = arc_files
end

s.resource_bundle  = { 'ProjectCore' => 'ProjectCore/**/*.{png,jpg,xib,strings}' }


s.dependency 'FBSDKLoginKit', '~> 4.11'
s.dependency 'FBSDKShareKit', '~> 4.11'
s.dependency 'NSHash', '~> 1.1'
(...)

end

      

        
        
        
      

    

But my only mistake:

- ERROR | [ProjectCore/ARC] xcodebuild: Returned an unsuccessful exit code.
