Instruments are getting crashed while performing tap operations on some buttons of ios app


We are automating an app in IOS. While performing tap operations on few buttons the instruments are getting crashed and app is getting closed unexpectedly. Please find the error log below:

Could anyone please help me how to resolve the issue

Thanks and Regards,


We are automating the app in a real device IPOD. The details of my machine are:
Appium: 1.3.1
IOS: 10.10

Observation: The same tap operation is working fine on IPAD. We are facing this issue in IPOD only.


Please report this on GitHub so we can fix. There are a number of problems related to iOS buttons that the devs are working on resolving. If this doesn’t get reported on the issue tracker though then it won’t be addressed.
