import PackageDescription

let package = Package(
    name: "sparql",
    dependencies: [
        // Dependencies declare other packages that this package depends on.
        .package(url: "https://github.com/banjun/SwiftSparql", from: "0.2.0"),
    targets: [

import Foundation
import SwiftSparql

For example:

// construct query
let q = SelectQuery(
    where: WhereClause(patterns:
            .rdfTypeIsImasIdol() // in the followings, verbs for this type can be auto-completed
            .imasType(is: "Cu")
            .foafAge(is: 17)
            .schemaName(is: Var("name"))
            .schemaHeight(is: Var("height"))
    order: [.desc(v: Var("height"))])

// capture results by Codable type
struct Idol: Codable {
    var name: String
    var height: Double

// request query to the endpoint URL
Request(endpoint: URL(string: "https://sparql.crssnky.xyz/spql/imas/query")!, select: q)
    .onSuccess { (idols: [Idol]) in // Codable type annotation for being decoded by fetch()
        idols.forEach { idol in
            print("\(idol.name) (\(idol.height)cm)")
    }.onFailure {fatalError(String(describing: $0))}
