Generate offline map (basemap by reference) bug

[vquach2404]

While updating the TPK for this sample, I found that the sample does not behave as expected. This sample should prompt the user to select either a local or online basemap. However, the sample currently does not prompt the user.

Currently this filename is an empty string

The doc is a bit confusing, but I think there are 2 possibilities

• The author of the online web map doesn't specify a default local basemap filename to use
• In order to use the local tile package, we need to set instead of get this property, i.e. let url = Bundle.main.url(forResource: "{path_to}/naperville_imagery", withExtension: "tpkx"), then set the filename and directory accordingly, i.e.

parameters.referenceBasemapFilename = url.lastPathComponent
parameters.referenceBasemapDirectory = url.deletingLastPathComponent()

The second idea gives me the result above, but I can not tell if it is expected. 😓
