I am also getting same issue. Is there any update on this?

After the line that looks something like:
CFMutableDataRef dataRef = CFDataCreateMutable(NULL, _someValue_);

Make sure to add:
CFDataSetLength(dataRef, _someValue_);

iOS11 doesn't allow instantiating CGDataProviderCreateWithCFData(dataRef) if dataRef is null. CFDataSetLength fixes that for you.

edit: maybe look for CGDataProviderCreateWithData and for length of passed in data. Should have set its length before passing in.
