这是我在.travis.yml文件中的代码，运行构建通过后，我发现测试失败。我对此一无所知，并阻止了我几天，感谢您的帮助。谢了

Done. Your build exited with 1.

---我的代码如下---

language: objective-c
osx_image: xcode10
xcode_workspace: aaaa.xcworkspace
xcode_scheme: aaaa
xcode_destination: platform=iOS Simulator,OS=9.1,name=iPhone 6

before_install:
  - pod repo update
  - npm install ios-sim -g
  - ios-sim start --devicetypeid "com.apple.CoreSimulator.SimDeviceType.iPhone-6, 9.1"

【问题讨论】：

我怀疑你跑题了，这不是一个与 Objective-C 相关的问题：显然它是一个 iOS 模拟器的东西。顺便说一句，您是否尝试查找该错误？似乎有很多关于它的信息
@il3v um..这个问题困扰了我一天，搜索了很多解决方案，但还是不行
您确定设备正确吗？您指定他们的 UDID 的事实对我来说并不合适。另外，您是否尝试将它们全部删除并逐个添加，看看它是否与仅一种测试设备无关？
@il3v 检查了 UDID 是否正确。我是用Xcode10.1构建的，只有12.1的设备构建和测试成功。其他人只构建成功而测试失败。

【解决方案1】：

问题可以通过以下步骤解决：

更改.travis.yml文件中osx_image的版本并重试

// if xcode10.1 build failed, you can change to other version, like xcode9.4
osx_image: xcode10.1

Travis 支持 xcode 版本列表： https://docs.travis-ci.com/user/languages/objective-c/
