Hello,
Thanks for the quick reply.
I’m also using a similar code, but I tried your shared code on a new app just in case.
It resulted the same. It is crashing at the point when it tries to set the ‘coordinate’ variable. 
I can get the ‘nativeEvent’ value, but not the ‘coordinate’.
‘nativeEvent’ says ‘null’ when I text it to the label.
The only difference is the “get property of object”. In my version this format not available. But I think it should be not a problem.
Thanks,
Gábor
