为什么 Spec lint 抛出错误 Xcode build failed: Returned an unsuccessful exit code？

Question

我正在尝试通过 cocoapods 创建一个自定义框架以在我的 Xcode 项目中使用。我按照此处提供的指南进行操作：https://guides.cocoapods.org/making/specs-and-specs-repo.html

当我尝试 lint 我的 pod 文件（通过 Podspec create 创建）时，我会收到以下错误：

ERROR | [iOS] xcodebuild: Returned an unsuccessful exit code.

The specific build system error: Build system information
    error: Multiple commands produce 

软件详情：

Xcode 版本：版本 10.0 (10A255) Swift 版本：Swift 4.2 Cocoapods 版本：1.6.0.beta.1

这些是我复制的步骤：

Pod 规范文件

 Pod::Spec.new do |s|

      s.name         = "iMessageFramework"
      s.version      = "1.0.0"
      s.summary      = "Small test to test code sharing via cocoapods."
      s.description  = "This is some superl oco framework that was made by 
       kevin vugts."
      s.homepage     = "https://github.com/kevinvugts/"
      s.license      = "MIT"
      s.author       = { "Kevin Vugts" => "kevin-vugts@live.com" }
      s.platform     = :ios, "11.0"
      s.source       = { :git => 
     "https://github.com/kevinvugts/iMessageFramework.git", :tag => "1.0.0" 
       }
      s.source_files = "iMessageFramework/**/*"
      s.swift_version = '4.2'
      s.ios.deployment_target  = '11.0'
    end

错误输出：

Answer 1

podspec 包含 s.source_files = "Constrictor/Constrictor/**/*" 包括所有文件，包括正在添加的 Info.plist 文件，就好像它们是源文件一样。

要么将文件移出 glob，要么使用 s.exclude_files = "Projectname/Projectname/*.plist" 从编译中排除这些文件。

Answer 2

将以下脚本添加到 PodSpec 文件。它应该可以解决问题。

s.pod_target_xcconfig = {
    'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'arm64'
  }
  s.user_target_xcconfig = { 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'arm64' }
