制作私有组件Podspec兼容M1芯片遇到的问题，由于M1芯片下模拟器支持arm64，导致支持混乱，在Podspec中添加声明模拟器忽略arm64即可解决问题，添加如下：

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

xcodebuild: Returned an unsuccessful exit code.报错解决如下：

   s.pod_target_xcconfig = { 'VALID_ARCHS' => 'x86_64 armv7 arm64' }
