Xcode 26.2 升级WCDB.objc 2.1.15下载不成功；WCDB 2.1.15下载成功，报C++17标准找不到；

end

全局统一 C++ 标准（覆盖主项目 + 所有 Pod）

post_install do |installer|

1. 统一所有 Target 的 C++17 配置（包括主项目和 Pod）

installer.pods_project.targets.each do |target| target.build_configurations.each do |config| # 强制设置 C++ 17 标准（gnu++17 兼容性更好） config.build_settings['CLANG_CXX_LANGUAGE_STANDARD'] = 'gnu++17' # 强制设置 C++ 标准库为 libc++ config.build_settings['CLANG_CXX_LIBRARY'] = 'libc++' # 确保部署版本和项目一致（避免版本冲突） config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0' # 清除可能干扰的自定义 C++ 编译参数 config.build_settings.delete('OTHER_CPLUSPLUSFLAGS') end end

2. 额外针对 WCDB 兜底（防止上述全局配置未生效）

installer.pods_project.targets.each do |target| if target.name == 'WCDB' || target.name == 'WCDBOptimizedSQLCipher' target.build_configurations.each do |config| # 显式指定 C++17（Xcode 识别的另一种写法） config.build_settings['CXX_STANDARD'] = '17' config.build_settings['CXX_STANDARD_LIBRARY'] = 'libc++' end end end

3. 修复 Xcode 26 可能的缓存问题

installer.pods_project.save() end
