Xcode12适配The linked library is missing one or more architectures required by this target问题

问题
升级到Xcode12后，运行Release模式后，会提示以下信息：

The linked library 'xxxx.a/Framework' is missing one or more architectures required by this target: armv7.

又或者

xxx/Pods/Target Support Files/Pods-xxx/Pods-xxx-frameworks.sh: line 128: ARCHS[@]: unbound variable

Command PhaseScriptExecution failed with a nonzero exit code

以上涉及架构问题

解决方案

在Target-Build Settings-Excluded Architectures中添加以下代码

EXCLUDED_ARCHS__EFFECTIVE_PLATFORM_SUFFIX_simulator__NATIVE_ARCH_64_BIT_x86_64=arm64 arm64e armv7 armv7s armv6 armv8 EXCLUDED_ARCHS=$(inherited) $(EXCLUDED_ARCHS__EFFECTIVE_PLATFORM_SUFFIX_$(EFFECTIVE_PLATFORM_SUFFIX)__NATIVE_ARCH_64_BIT_$(NATIVE_ARCH_64_BIT))
