根据这个帖子STF 集成 iOS 之 开源了

目前但效果只是能发现设备，还无法正常完成初始化。

遇到的问题都是摸黑解决：

https://github.com/mrx1203/stf.git
https://github.com/mrx1203/WebDriverAgent.git

WDA的环境搭建参考为iOS真机安装WebDriverAgent

问题：在Xcode 10.3上编译会报错：

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_XCEventGenerator", referenced from:
      objc-class-ref in FBCustomCommands.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

根据test failed on Xcode 10.2这个建议，先使用9.4版本的XCTest.framework替换后，编译通过，但启动会报错——

2019-10-12 11:36:37.335636+0800 WebDriverAgentRunner-Runner[3948:11746943] libMobileGestalt MobileGestalt.c:890: MGIsDeviceOneOfType is not supported on this platform.
2019-10-12 11:36:37.885546+0800 WebDriverAgentRunner-Runner[3948:11746943] Running tests...
dyld: lazy symbol binding failed: Symbol not found: __XCTLoadTestConfiguration

需要使用10.1版本但Xcode对应但XCTest.framework才可以。

辅助根据问题：could not connect to lockdownd, error code xx只有idevice_id 可以使用。可能是libimobiledevice版本问题。

Error: Cannot find module 'eslint-config-appium' while running ./Scripts/bootstrap.sh

could not connect to lockdownd, error code xx

更换设备后，选择WebDriverAgentRunner，进行自动签名。

#此方案可行
brew update
brew uninstall --ignore-dependencies libimobiledevice
brew uninstall --ignore-dependencies usbmuxd
brew install --HEAD usbmuxd
brew unlink usbmuxd
brew link usbmuxd
brew install --HEAD libimobiledevice

目前还是一团浆糊的脑子，折腾得有点懵。

#环境准备
#  安装libimobiledevice等依赖工具，如果已经安装过，可能需要升级，先卸载，再安装最新版本
    brew uninstall --ignore-dependencies libimobiledevice
    brew uninstall --ignore-dependencies usbmuxd
    brew install --HEAD usbmuxd
    brew unlink usbmuxd
    brew link usbmuxd
    brew install --HEAD libimobiledevice
    brew install --HEAD ideviceinstaller
    brew install carthage
    brew install socat
