Answer 1

基于此thread的临时解决方案：

重命名文件 com.apple.nsurlsessiond(Dont delete) in

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/UserEventPlugins/com.apple。 nsurlsessiond.plugin/

到某事-com.apple.nsurlsessiond

还有文件nsurlsessiond（不要删除）

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/libexec/

到某事-nsurlsessiond
