I have a quite large (~200k) list of simple objects like:

struct City {
    let id: Int
    let name: String
    let lat: Double
    let lon: Double
}

and I want to embed in into my application. I believe, hardcoding it in a .swift file is not the best option. I've tried to embed it as a JSON file, but the loading speed is poor for this method. I've also tried a Message Pack serializer, but it seems to be as slow as JSON in my case.

What would be a proper way to embed it? I think, using Core Data would be too much for this situation. I think, with the fact that my data is so simple and I don't need any kind of backward compatibility it must be and easier solution.

What’s your usage like? Do you really need to load all 200k entries? – Alexander Jan 17 '21 at 21:44
You can embed it as raw data – Leo Dabus Jan 17 '21 at 22:01
Do you need this all this data available in memory all at once? – Leo Dabus Jan 17 '21 at 22:07

https://stackoverflow.com/a/64669393/2303865 this might be a better duplicate considering that this struct contains a string – Leo Dabus Jan 18 '21 at 03:11
