Removed back button on uinavbar and replaced with discard all button which is the same as back button just more descriptive. The root view controller now created both the data selection vc and the staging vc and created the strongly referenced data collection which is one feature collection. This allows for a smoother UI. Data conversion to json dict is more crash safe. All properties are checked for nil before adding to dict. Added send and save feature collection in staging. Now allocating new cllocation object for geotagging images, this ensures that each image is geotagged with fresh gps coords.
