Getting data

To get our data out of the plist, add the following method above loadData() inside of ExploreDataManager:

func fetch() {
for data in loadData() {
print(data)
}
}

Inside of your ExploreViewController.swift file, delete the previous print statement that was inside your viewDidLoad() and replace it with the following:
