Unable to Parse Activity Monitor trace

[irfan-cloudnix]

Initially when I ran the compiled project passing activity_monitor.trace file, it threw "Data processor has not been implemented for this type of instrument." because instrumentID was not compared to exact value, after modifying & running again, it is throwing error like

Instrument: Activity Monitor (com.apple.xray.instrument-type.activity)

很简单，不兼容呗。
你的设备肯定是iOS11.3以上了，貌似tracedump最高只支持到11.2
