我在Teamcity的构建日志中有一个警告。我已将CI-Server上的Xcode从7.3.1更新为8。该步骤成功运行，但是我有:
[Step 3/3] Starting: /Users/teamcity/local/teamcity-build-agent/temp/agentTmp/custom_scriptxxxxxxx

我该如何解决此警告？
最佳答案
我遇到过同样的问题。我必须在Jenkins服务器中同时运行Xcode 7(以构建旧版本)和Xcode 8(以构建当前的develop分支)，而我一直都遇到这个问题。
解:
launchctl remove com.apple.CoreSimulator.CoreSimulatorService || true
发生这种情况是因为，即使您退出了模拟器应用程序，该服务仍在运行。需要上述命令来删除名为
com.apple.CoreSimulator.CoreSimulatorService的服务。 || true是为了避免该服务未运行时失败。
