Is there a way to export a Symbol Instance with its overriden image?
Zeplin does it well, as explained here: https://blog.zeplin.io/exporting-assets-from-symbols-in-sketch-1e1b44d33722#c20c
I'm able to use
modifiedMasterByApplyingInstance_inDocument_ to get the expanded version of the instance, but it is an ImmutableSymbolMaster and asking to export it results in the error
[MSImmutableSymbolMaster documentData]: unrecognized selector sent to instance 0x7fcf438335b0.
