Read data from plist - swift3

Question

I'm trying to convert my own app from Objective-C to Swift 3.
Try is a sample of my plist:
elements.plist
I'm trying this code I found in another similar question:
//get the path of the plist file
guard let plistPath = Bundle.main.path(forResource: "elements", ofType: "plist") else { return }
print("plistPath:", plistPath)
//load the plist as data in memory
guard let plistData = FileManager.default.contents(atPath: plistPath) else { return }
print("plistData:", plistData)
//use the format of a property list (xml)
var format = PropertyListSerialization.PropertyListFormat.xml
//convert the plist data to a Swift Dictionary
guard let plistDict = try! PropertyListSerialization.propertyList(from: plistData, options: .mutableContainersAndLeaves, format: &format) as? [String : AnyObject] else { return }
print("plistDict:", plistDict)
//access the values in the dictionary
if let value = plistDict["DescrizioneEsercizio"] as? String {
//do something with your value
print(value)
}
Please, let me know how can I import data from plist and access a single field in Swift 3.

Have a look at the plist. It contains an array of dictionaries.
guard let plistDicts = try! PropertyListSerialization.propertyList(from: plistData, options: .mutableContainersAndLeaves, format: &format) as? [[String : AnyObject]]
else {
return
}
// See how it is casted to an Array of Dictionaries ([[String : AnyObject]]) here
Now you can iterate over your dicts and do what you need:
for dict in plistDicts {
if let value = plistDict["DescrizioneEsercizio"] as? String {
//do something with your value
print(value)
}
}
