I'm learning how to get data using Github API and making a simple app in swift. Tutorials I've been watching make an empty array and geting response function in the same controller file. However, I want my view controller to keep as small as possible, and I decided to create getting data function in another file. My question is how can I access the empty array in a different file after I fetch data. Maybe this explanation make you confused, so I put my code below.
This is my view controller file, and I want to populate the repositories array after fetch the data using an API call.
import UIKit
class RepositoryListVC: UIViewController {
var tableView = UITableView()
var repositories: [Repository] = []
override func viewDidLoad() {
super.viewDidLoad()
title = "AAAAAA"
configureTableView()
Service.fetchData()
}
func configureTableView() {
view.addSubview(tableView)
tableView.delegate = self
tableView.dataSource = self
tableView.rowHeight = 100
tableView.register(RepositoryCell.self, forCellReuseIdentifier: Cells.repositoryCell)
tableView.pin(to: view)
}
}
extension RepositoryListVC: UITableViewDelegate, UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 10
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: Cells.repositoryCell) as! RepositoryCell
cell.set()
return cell
}
}
This is the file for fetching data using an API call. I want to populate the repository valuable in the view controller file above. I have successfully get data and parse JSON data, so I want to push Repository(...) to repository array, but I was not able to figure out how...
import UIKit
import SwiftyJSON
import Alamofire
struct Service {
static func fetchData() {
AF.request(API.gitHubEndpoint).responseJSON { (response) in
switch response.result {
case .success(let value):
let json = JSON(value)
let repositoryItemArr = json["items"].arrayValue
for item in repositoryItemArr {
Repository(userImageUrl: item["owner"]["avatar_url"].stringValue, userName: item["owner"]["user_name"].stringValue, repositoryName: item["owner"]["repository_name"].stringValue, starNum: item["owner"]["star_number"].intValue)
}
case .failure(let error):
print(error)
}
}
}
