为什么run不起来呢，error code -21

[li-qingnan]

ERROR: Could not connect to lockdownd, error code -21

[HongliYu]

ERROR: Could not connect to lockdownd, error code -19

[CatOnly]

我也是
真机测试：iOS 10.1，Xcode 8.0，OSX 10.11.6
ERROR: Could not connect to lockdownd, error code -21
然后又报错
instruments[31689:8241998] *** -[__NSCFConstantString stringByAppendingPathExtension:]: cannot append extension 'tracetemplate' to path ''
Instruments Usage Error: The specified template '' does not exist.

我还发现了一个十分相似的产品 https://github.com/mokemokechicken/CrashMonkey

执行命令：smart_monkey -a ＊＊＊ -w 38a5b6235492941678c39b9ac24cf9c31ddbc9e5 --event-number 1000
我也是报这个错，如果用模拟器的话提示Invalid device, Please given a vaild device!
求回复～

大神，是不是升级到XCode8之后Monkey就不支持了，之前用XCode7.3.1是可以的！
帮忙看看吧，不胜感激！错误日志如下：

XCode8去掉了UIAutomation，应该是无解了。等待作者更新版本，加油哦！

@ruanshurui一模一样的情况额...第一次使用这个工具，不知道是不是像楼上说的，在Xcode8上用不了
