My app receives TIFF files with Annotations in the header which I need to turn into annotation objects.
Reading the tag is easy enough:

// get the annotation data, if any. show an error upon failure.
    LTRasterTagMetadata *metadata = [rasterCodecs readTag: LTRasterTagMetadataAnnotationTiff
                                                 fromFile: filename
                                               pageNumber: 1
                                                    error: &error];

but what do I do next?
Is there an ObjC API to turn the metadata.data (which is an NSData* type. More specifically an OS_dispatch_data*) into a collection of AnnCodec objects?
