So below is the part of the code (in SwiftUI) where local JSON file is used, I want to use remote JSON instead of local, could someone help?

Source is (https://developer.apple.com/tutorials/swiftui/building-lists-and-navigation)

so instead local

landmarkData.json

I want to use https://lkakashv.github.io/landmarkData.json

let landmarkData: [Landmark] = load("landmarkData.json")


func load(_ filename: String) -> T {
    let data: Data
    
    guard let file = Bundle.main.url(forResource: filename, withExtension: nil)
        else {
            fatalError("Couldn't find \(filename) in main bundle.")
    }
    
    do {
        data = try Data(contentsOf: file)
    } catch {
        fatalError("Couldn't load \(filename) from main bundle:\n\(error)")
    }
    
    do {
        let decoder = JSONDecoder()
        return try decoder.decode(T.self, from: data)
    } catch {
        fatalError("Couldn't parse \(filename) as \(T.self):\n\(error)")
    }
}

Thank you

Did you try to use URLRequest ?

        if let url = URL(string:  "your url")
            let request = NSMutableURLRequest(url: url)
          
            let task = URLSession.shared.dataTask(with: request as URLRequest) {
                data, response, error in

     // process here

You asked this SwiftUI question twice here.

Did you get the answer ? If so, thanks to close both threads.
