I have a plist which is an array of dictionaries. (root is array).
Each dic have 2 values for sure : name, and icon as Strings.
But some of them have more keys/values, some don't.

I am trying to read the array into a structure with :

struct Config: Decodable 
 private enum CodingKeys: String, CodingKey 
 case name, icon
 

 let name: String
 let icon: String




func functionsStruct() -> Config 
 let url = Bundle.main.url(forResource: "FunctionsList", withExtension: "plist")!
 let data = try! Data(contentsOf: url)
 let decoder = PropertyListDecoder()
 return try! decoder.decode(Config.self, from: data)

1. I read a dictionary, how to read an array of dictionaries and how to set up the structure.




2. how to solve it that some dics have keys that others don't ?

For your first question :

I read a dictionary, how to read an array of dictionaries and how to set up the structure.

func functionsStruct() -> [Config] 
 let url = Bundle.main.url(forResource: "FunctionsList", withExtension: "plist")!
 let data = try! Data(contentsOf: url)
 let decoder = PropertyListDecoder()
 return try! decoder.decode([Config].self, from: data)
 

As simple as that!!!

If you want an array of dictionaries, then you don't need to create your own Codable class. Arrays and dictionaries already implements Codable.

Just do:

func functionsStruct() -> [[String: String]] 
 let url = Bundle.main.url(forResource: "FunctionsList", withExtension: "plist")!
 let data = try! Data(contentsOf: url)
 let decoder = PropertyListDecoder()
 return try! decoder.decode([[String: String]].self, from: data)

Or use [[String: Any]] if the dictionary contains values other than strings.

And then you can access your name and icon like this:

let dicts = functionsStruct()
print(dicts[0]["name"])

However, I don't understand why you insist on using a dictionary. I strongly recommend you to stick with a Codable struct. You can make optional keys optional:

struct Config: Decodable 
 let name: String
 let icon: String
 let optionalKey1: String?
 let optionalKey2: String?

Their values will be nil if the key does not exist in the plist.

And you need to decode an array of Config, instead of just Config like you did:

return try! decoder.decode([Config].self, from: data)
