二、问题：

Currently pod trunk is not usable for us as pod lint fails because simulator architectures (i386 and x86_64) are missing. BUT Apple rejects apps containing dynamic-frameworks with simulator architectures.

We deploy two variants of dynamic-framworks

one with all device and simulator architectures (for debugging)
one with device-only architectures (for app-submission).

pod lint fails with the following errors:

x86_64 in file SampleSDK/iOS/Sample.framework/Sample (3 slices)

NOTE | [SampleSDK/SampleSDK and more...] xcodebuild: fatal error: lipo: -remove's specified would result in an empty fat file

NOTE | [iOS] [SampleSDK/SampleSDK] xcodebuild: ld: warning: ld: warning: ignoring file SampleSDK/iOS/Sample.framework/Sample, missing required architecture x86_64 in file

We were forced to provide device-only architectures as Apple rejects app-submissions containing any simulator-architectures with

ERROR: ERROR ITMS-90087: "Unsupported Architectures. The executable for Sample.app/Frameworks/Sample.framework contains unsupported architectures '[x86_64, i386]'."

三、答案

方法一：

@eldewy I managed to go around this issue by replacing the code inside the xcodebuild function of validator.rb by that one :

def xcodebuild
require 'fourflusher'
command = ['clean', 'build', '-workspace', File.join(validation_dir, 'App.xcworkspace'), '-scheme', 'Pods-App', '-configuration', 'Release']
case consumer.platform_name
when :ios
command += %w(-sdk iphoneos10.0 -destination=generic/iOS ONLY_ACTIVE_ARCH=NO ARCHS=armv7)
when :watchos
command += %w(CODE_SIGN_IDENTITY=- -sdk watchsimulator)
command += Fourflusher::SimControl.new.destination(:oldest, 'watchOS', deployment_target)
when :tvos
command += %w(CODE_SIGN_IDENTITY=- -sdk appletvsimulator)
command += Fourflusher::SimControl.new.destination(:oldest, 'tvOS', deployment_target)
end

  output, status = _xcodebuild(command)

  unless status.success?
    message = 'Returned an unsuccessful exit code.'
    message += ' You can use `--verbose` for more information.' unless config.verbose?
    error('xcodebuild', message)
  end
  output
end

I basically replicated the behaviour of 0.39 to allow our team to push pods. Please note that this is a quick and dirty fix, will only work for ios targets, is only working with xcode8, and might not work for you, but I thought it might help you while waiting for an official fix ;)

方法二：

Hi,
I also ran into the same issue while creating a private pod to wrap a third-party which does not provide i386 libraries : pod lib lint resulted into Undefined symbols for architecture i386.
Finally, I came up with the following workaround (which is a posteriori natural, since my project really doesn't need to be built on i386) : tell the podspec that the project is not buildable on 32 bit simulators, that is :

    subspec.pod_target_xcconfig = {
        'ARCHS[sdk=iphonesimulator*]' => '$(ARCHS_STANDARD_64_BIT)'
    }

(instead of the default ARCHS_STANDARD)

In case it helps... @MarcoBrescianini @dvdblk @lumialxk

方法三（已验证可行）：

I almost have the same case with @hberenger . But the third-party in my private pod does not include both i386 and x86_64 libraries.
I add pod_target_xcconfig like this:

s.pod_target_xcconfig = { 'VALID_ARCHS[sdk=iphonesimulator*]' => '' }

after that, pod lib lint --skip-import-validation works for me.

I just hope "the lint" can ignore architecture i386 and x86_64. I'm not sure whether it is the right way, though it works.

方法四：

This show how to fix

when :ios
        command += %w(CODE_SIGN_IDENTITY=- -sdk iphonesimulator ARCHS=x86_64)
