what i want my app to do is to fetch the data from the database and display it in the aboutmeviewcontroller, however the app wont even run, i tried following a tutorial on youtube https://www.youtube.com/watch?v=ge56yTgnjKs&t=263s thats the link, however I keep on getting an error, can someone please help!
this is the error im getting.
"Unable to simultaneously satisfy constraints.

Ok so, I am trying to make a custom table that has a news feed from newsapi, from my debugging: the api calls and such get made and the data is acessed, its just that it doesnt display on the table, it shows up as a blank table.
Here is the code:
This is from the "first view controller" as I am using the tabbed template
import UIKit
class FirstViewController: UIViewController, UITableViewDelegate,UITableViewDataSource {
#IBOutlet weak var tableView: UITableView!
var articles: [Article]? = []
override func viewDidLoad() {
super.viewDidLoad()
fetchArticles()
}
func fetchArticles(){
let urlRequest = URLRequest(url: URL(string: "https://newsapi.org/v2/top-headlines?country=us&?category=business&apiKey=sorrynotgivingmykey")!)
let task = URLSession.shared.dataTask(with: urlRequest){(data,response,error) in
if error != nil{
print(error)
return
}
self.articles = [Article]()
do{
let json = try JSONSerialization.jsonObject(with: data!, options: .mutableContainers) as! [String: AnyObject]
if let articlesFromJson = json["articles"] as? [[String: AnyObject]]{
for articlesFromJson in articlesFromJson{
let article = Article()
if let title = articlesFromJson["title"] as? String, let desc = articlesFromJson["description"] as? String, let url = articlesFromJson["url"] as? String, let imageToUrl = articlesFromJson["urlToImage"] as? String, let date = articlesFromJson["publishedAt"] as? String{
article.headline = title
article.desc = desc
article.url = url
article.imageUrl = imageToUrl
article.date = date
// print(article.date)
// print(article.headline)
}
self.articles?.append(article)
}
}
DispatchQueue.main.async {
self.tableView.reloadData()
}
}catch let error{
print(error)
}
}
task.resume()
// print(articles)
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.articles!.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "worklmao", for: indexPath) as! ArticleCell
cell.title.text = self.articles?[indexPath.item].headline
cell.desc.text = self.articles?[indexPath.item].desc
cell.date.text = self.articles?[indexPath.item].date
print("lol lmao hahax help fuck shit")
return cell
}
func numberOfSections(in tableView: UITableView) -> Int {
1
}
}
And this is the cell classes I used for the articles
import UIKit
class ArticleCell: UITableViewCell {
#IBOutlet weak var date: UILabel!
#IBOutlet weak var desc: UILabel!
#IBOutlet weak var title: UILabel!
#IBOutlet weak var ImgView: UIImageView!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
This is the article class
import UIKit
class Article: NSObject {
var headline: String?
var desc: String?
var url: String?
var date: String?
var imageUrl: String?
}
and bare in mind I did setup the class for the cell properly(at least I think
Still, this is what I get:
Don't forget to connect dataSource and delegate for tableView.
Change your tableView outlets to this:
#IBOutlet weak var tableView: UITableView! {
didSet {
tableView.delegate = self
tableView.dataSource = self
}
}
Some points:
You don't have to declare articles array as optional. Simply do this :
var articles = [Article]()

I have a tableview of "Books" that are stored in Realm. I want to set the "CurrentBook" property to "True" when hitting a button on a custom UITableViewCell.
I believe my error has something to do with getting the correct book value in "func selectCurrentBook", when I use an optional like below nothing happens.
#objc func selectCurrentBook(sender: UIButton) {
try! realm.write {
book?.currentlyReading = true
}
}
When I don't use an optional for book and use book.currentlyReading = true I get the error "Unexpectedly found nil while implicitly unwrapping an Optional value:"
Am I incorrectly passing the book value somewhere? I can't seem to find out how. Maybe I'm delegating wrong?
My TableViewCell is:
import UIKit
import RealmSwift
protocol MyBooksDelegate {
func currentlyReadingButton()
}
class MyBooksTableViewCell: UITableViewCell {
let realm = try! Realm()
#IBOutlet weak var titleLabel: UILabel!
#IBOutlet weak var authorLabel: UILabel!
#IBOutlet weak var smallThumbnailImageView: UIImageView!
#IBOutlet weak var currentlyReadingButton: UIButton!
#IBAction func currentlyReadingButton(_ sender: Any) {
}
private var book: Book!
func loadImage(smallThumbnailURL: String) {
let imageURL = URL(string: smallThumbnailURL ?? "")
smallThumbnailImageView.sd_setImage(with: imageURL)
}
func configureCell(book: Book, delegate: MyBooksDelegate?) {
titleLabel.text = book.bookTitle
authorLabel.text = book.bookAuthor
loadImage(smallThumbnailURL: book.bookSmallThumbnailImageURL)
currentlyReadingButton.addTarget(self, action: #selector(selectCurrentBook(sender:)), for: .touchUpInside)
}
#objc func selectCurrentBook(sender: UIButton) {
try! realm.write {
book?.currentlyReading = true
}
}
}
My View Controller with TableView is :
import SwiftyJSON
import RealmSwift
class BooksViewController: UIViewController, UITextFieldDelegate, UITableViewDataSource, UITableViewDelegate {
#IBOutlet weak var myBooksTableView: UITableView!
let realm = try! Realm()
var books: Results<Book>?
// Search Bar Properties
var searchParameter = "intitle"
var booksArray: [Book] = []
override func viewDidLoad() {
super.viewDidLoad()
loadBooks()
// Setting up the TableView
self.myBooksTableView.delegate = self
self.myBooksTableView.dataSource = self
self.myBooksTableView.rowHeight = 120.0
// Setup Title
title = "My Books"
// navigationController?.navigationBar.prefersLargeTitles = true
}
override func viewWillAppear(_ animated: Bool) {
navigationController?.navigationBar.barStyle = .black
loadBooks()
}
func loadBooks() {
books = realm.objects(Book.self).sorted(byKeyPath: "DateCreated", ascending: false)
myBooksTableView.reloadData()
}
// TABLEVIEW
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return books?.count ?? 1
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if let cell = tableView.dequeueReusableCell(withIdentifier: "MyBooksTableViewCell", for: indexPath) as? MyBooksTableViewCell {
cell.configureCell(book: (books?[indexPath.row])!, delegate: self as? MyBooksDelegate)
// cell.selectionStyle = UITableViewCell.SelectionStyle.none
return cell
} else {
return UITableViewCell()
}
}
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
self.performSegue(withIdentifier: "myBooksTOMyBooksDetail", sender: self)
myBooksTableView.deselectRow(at: indexPath, animated: true)
}
And my Book Model is:
class Book: Object {
#objc dynamic var bookTitle: String!
#objc dynamic var bookAuthor: String!
#objc dynamic var bookSmallThumbnailImageURL: String!
#objc dynamic var bookThumbnailImageURL: String!
#objc dynamic var bookDescription: String!
#objc dynamic var bookISBN_13: String!
#objc dynamic var currentlyReading = false
#objc dynamic var DateCreated = Date()
#objc dynamic var WordID = UUID().uuidString
// words
let words = List<Word>()
override static func primaryKey() -> String? {
return "WordID"
}
}
The most compatible syntax is
currentlyReadingButton.addTarget(self, action: #selector(selectCurrentBook), for: .touchUpInside)
and
#objc func selectCurrentBook(_ sender: UIButton) {
However as the cell is custom anyway I'd prefer an IBAction over target/action
And the protocol MyBooksDelegate seems to be unused.
Side note:
Force unwrap the cell
let cell = tableView.dequeueReusableCell(withIdentifier: "MyBooksTableViewCell", for: indexPath) as! MyBooksTableViewCell
A crash – with report – reveals a design mistake which can be fixed instantly. With the if let you'll see nothing and have no clue why.
Update:
The crash occurs because you don't set book in the cell, add the first line after the {
func configureCell(book: Book, delegate: MyBooksDelegate?) {
self.book = book
titleLabel.text = book.bookTitle
...
I am creating an events feed, using a table view and Firebase as my database. I am using dateformatter with a style type of full for date and short for time and writing it to my database as a string which is perfect, it writes exactly how i want it to.
However, when i try to read the data from firebase and display it on my textlabel in the tableview cell i get the following error.
Error:
"Fatal error: Index out of range
2019-08-30 11:01:35.001667-0400 fmcBeta[58563:3478851] Fatal error: Index out of range"
Any help would be greatly appreciated i am self learning and fairly new to swift.
This is my table view cell:
class EventsTableViewCell: UITableViewCell {
#IBOutlet weak var eventLocation: UILabel!
#IBOutlet weak var eventDate: UILabel!
#IBOutlet weak var eventTitle: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
This is my viewcontoller with tableview protocols:
class EventsViewController: UIViewController,UITableViewDelegate,UITableViewDataSource {
#IBOutlet weak var tableView: UITableView!
var eventsRef: DatabaseReference?
var eventsDatabaseHandle:DatabaseHandle?
var eventsTitles = [String]()
var eventTimestamps:[String] = []
var eventsLocations = [String]()
eventsRef = Database.database().reference()
tableView.reloadData()
tableView.transform = CGAffineTransform(rotationAngle: -CGFloat.pi)
tableView.delegate = self
tableView.dataSource = self
eventsDatabaseHandle = eventsRef?.child("Church Events").observe(.childAdded, with: { (snaphot) in
let eventPost = snaphot.value as! [String: Any]
self.eventTimestamps.append(eventPost["eventdate"] as! String)
self.eventsTitles.append(eventPost["eventtitle"] as! String)
self.eventsLocations.append(eventPost["eventlocation"] as! String)
self.tableView.reloadData()
})
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return eventsTitles.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "events") as! EventsTableViewCell
cell.eventTitle.text! = eventsTitles[indexPath.row]
cell.eventDate.text! = eventTimestamps[indexPath.row]
cell.eventLocation.text! = eventsLocations[indexPath.row]
cell.transform = CGAffineTransform(rotationAngle: CGFloat.pi)
return cell
}
}
This is how i'm writing the data to Firebase
#IBAction func saveEventsButton(_ sender: Any) {
let eventsDates = DateFormatter.localizedString(from: eventDateSelector.date, dateStyle: DateFormatter.Style.full, timeStyle: DateFormatter.Style.short) as String
print(eventsDates.description)
let eventSaved:[String: Any] = ["eventdate": eventsDates,"eventtitle":eventsTitleTextField.text!,"eventlocation":eventsLocation.text!]
eventsRef.child("Church Events").childByAutoId().setValue(eventSaved)
self.dismiss(animated: true, completion: nil)
}
}
I am building a car sharing IOS App prototype. My app is link to firebase, i can retrieve and display journey data in a table view but when trying to pass the data in another view controller the data do not display. Below are my table View controller and view controllers source codes.
import UIKit
import Firebase
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
var myIndex = 0
var journeyList = [journeyModel]()
public func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return journeyList.count
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 150
}
// defining firebase reference var
var refjourney: DatabaseReference!
#IBOutlet weak var journeyTable: UITableView!
public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "searchCell", for: indexPath as IndexPath) as! journeySearchTableViewCell
var journe: journeyModel
journe = journeyList[indexPath.row]
print(journe.start!, journe.destination!, journe.date!, journe.driverName!)
cell.driverNameLabel.text = journe.driverName
cell.startLabel.text = journe.start
cell.destinationLabel.text = journe.destination
cell.dateLabel.text = journe.date
return cell
}
At this point the app functions correctly only faces issues when passing the data to another view controller
override func viewDidLoad() {
super.viewDidLoad()
Database.database().reference().child("Journey").observe(.value, with: { (snapshot) in
if snapshot.childrenCount > 0 {
self.journeyList.removeAll()
for journey in snapshot.children.allObjects as! [DataSnapshot] {
let journeyObject = journey.value as? [String: AnyObject]
let start = journeyObject?["startingPoint"]
let destination = journeyObject?["destinationPoint"]
let driverName = journeyObject?["driverName"]
let date = journeyObject?["tripDate"]
let id = journeyObject?["id"]
let journey = journeyModel(destination: destination as! String?, driverName: driverName as! String?, start: start as! String?, date: date as! String?, uid: id as! String?)
self.journeyList.append(journey)
}
self.journeyTable.reloadData()
}
})
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
performSegue(withIdentifier: "logged", sender: self)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
var bsVC: bookSetViewController = segue.destination as! bookSetViewController
}
#IBAction func backButton(_ sender: Any) {
dismiss(animated: true, completion: nil)
}
}
import UIKit
class bookSetViewController: UIViewController {
var getStart = String()
var getStop = String()
var getDate = String()
var getDriver = String()
#IBOutlet weak var startingLabel: UILabel!
#IBOutlet weak var stopingLabel: UILabel!
#IBOutlet weak var daterLabel: UILabel!
#IBOutlet weak var driveLabel: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
startingLabel.text! = getStart
stopingLabel.text! = getStop
daterLabel.text! = getDate
driveLabel.text! = getDriver
}
}
import UIKit
class journeySearchTableViewCell: UITableViewCell {
#IBOutlet weak var startLabel: UILabel!
#IBOutlet weak var destinationLabel: UILabel!
#IBOutlet weak var dateLabel: UILabel!
#IBOutlet weak var driverNameLabel: UILabel!
}
import UIKit
class journeyModel: NSObject {
var driverName: String?
var start: String?
var destination: String?
var date: String?
var uid: String?
init(destination: String?, driverName: String?, start: String?, date: String?, uid: String?) {
self.driverName = driverName
self.start = start
self.destination = destination
self.date = date
self.uid = uid
}
}
First things, first - don't share the whole project, just the bits that are needed.
The whole point of the prepare(for segue... is to get a handle to the new controller, and assign the values you need to pass over.
You will need to keep a track of which journey you're interested in. There are many ways to do this, but the easiest might be to extend what you do on the click row
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
{
// assume you have defined journeySelected as a class-level instance of journeyModel
journeySelected = journeyModel[indexPath.row]
performSegue(withIdentifier: "logged", sender: self)
}
and then
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
var bsVC: bookSetViewController = segue.destination as! bookSetViewController
bsVC.getStart = journeySelected.start
// and for all the other fields
}
I was looking for an answer for this question but I couldn't find anything. I'm new in swift programming and also in stackoverflow, so I hope anyone can help me.
I try to make an app with an "EditViewController" which is there with multiple textfields for name, prename, etc.
I'm able to save this "phonebook" entries, but I'm not able to sort the array by the property name.
The editing interface is only this code:
import UIKit
class EditViewController: UIViewController {
#IBOutlet weak var vornameTextField: UITextField!
#IBOutlet weak var nameTextField: UITextField!
#IBOutlet weak var adresseTextField: UITextField!
#IBOutlet weak var hausnummerTextField: UITextField!
#IBOutlet weak var plzTextField: UITextField!
#IBOutlet weak var ortTextField: UITextField!
#IBOutlet weak var telefonnummerTextField: UITextField!
#IBOutlet weak var berufTextField: UITextField!
override func viewDidLoad()
{
super.viewDidLoad()
}
override func didReceiveMemoryWarning()
{
super.didReceiveMemoryWarning()
}
}
The code for saving the textfields is:
import UIKit
class Telefonbuch: NSObject, NSCoding
{
var name: String!
var vorname: String!
var beruf: String!
var telefonnummer: String!
var adresse: String!
var hausnummer: String!
var plz: String!
var ort: String!
init(name: String, vorname: String, beruf:String, telefonnummer: String, adresse: String, hausnummer: String, plz: String, ort: String)
{
self.name = name
self.vorname = vorname
self.beruf = beruf
self.telefonnummer = telefonnummer
self.adresse = adresse
self.hausnummer = hausnummer
self.plz = plz
self.ort = ort
}
required init?(coder aDecoder: NSCoder) {
name = aDecoder.decodeObjectForKey("name") as? String
vorname = aDecoder.decodeObjectForKey("vorname") as? String
beruf = aDecoder.decodeObjectForKey("beruf") as? String
telefonnummer = aDecoder.decodeObjectForKey("telefonnummer") as? String
adresse = aDecoder.decodeObjectForKey("adresse") as? String
hausnummer = aDecoder.decodeObjectForKey("hausnummer") as? String
plz = aDecoder.decodeObjectForKey("plz") as? String
ort = aDecoder.decodeObjectForKey("ort") as? String
}
func encodeWithCoder(aCoder: NSCoder) {
aCoder.encodeObject(name, forKey: "name")
aCoder.encodeObject(vorname, forKey: "vorname")
aCoder.encodeObject(beruf, forKey: "beruf")
aCoder.encodeObject(telefonnummer, forKey: "telefonnummer")
aCoder.encodeObject(adresse, forKey: "adresse")
aCoder.encodeObject(hausnummer, forKey: "hausnummer")
aCoder.encodeObject(plz, forKey: "plz")
aCoder.encodeObject(ort, forKey: "ort")
}
static func saveArray(data: [Telefonbuch])
{
if data.count == 0 {return}
if let path = getFilePath() {
NSKeyedArchiver.archiveRootObject(data, toFile: path)
}
}
static func loadArray() -> [Telefonbuch]
{
if let path = getFilePath() {
if let result = NSKeyedUnarchiver.unarchiveObjectWithFile(path) as? [Telefonbuch]
{
return result
}
}
return [Telefonbuch]()
}
private static func getFilePath() -> String?
{
let pfd = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
if let pfad = pfd.first {
return pfad + "Kontakte.bin"
}else {
return nil
}
}
}
Now I would like to make the tableview, where I display the data, sorted and with header. But I'm not able to sort the [Telefonbuch] Array by property name.

Can anyone help me because I don't find a solution.
Thanks in advance.
You should be able to sort the array with:
kontaktListe.sort({ $0.name > $1.name })
