Undefined symbol: __swift_FORCE_LOAD_$_swiftCompatibility报错解决

xcode 汇编OC和swift的静态库报错

Undefined symbol: __swift_FORCE_LOAD_$_swiftCompatibility50
Undefined symbol: __swift_FORCE_LOAD_$_swiftCompatibility51
Undefined symbol: __swift_FORCE_LOAD_$_swiftCompatibility56
Undefined symbol: __swift_FORCE_LOAD_$_swiftCompatibilityConcurrency
Undefined symbol: __swift_FORCE_LOAD_$_swiftCompatibilityDynamicReplacements
Linker command failed with exit code 1 (use -v to see invocation)

报错的原因是因为没有Swift的运行环境，xcode不会自动创建Swift的运行环境的，所以新建一个Swift文件即可。
