import UIKit
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate{
#IBOutlet var tblView: UITableView!
var AnimalName = ["e":["Elephant","EEE"], "l":["Lion","LL"], "h":["Horse", "huh"]]
var initial: [String] = [] //error in this line
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return self.initial.count
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if let animalsOfSection = self.AnimalName[self.initial[section]] {
return animalsOfSection.count
}
return 0
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell")! as UITableViewCell
if let animal = self.AnimalName[self.initial[indexPath.section]]?[indexPath.row] {
cell.textLabel?.text = animal //how to call the cell
}
return cell
}
func sectionIndexTitlesForTableView(tableView: UITableView) -> [String]? {
return self.initial // not getting output
}
func tableView(tableView: UITableView, sectionForSectionIndexTitle title: String, atIndex index: Int) -> Int {
if let index = self.initial.indexOf(title) {
return index // How to select
}
return 0

override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.initial = Array(self.AnimalName.keys).sort(<)
}
}

Answer 2

["Horse",huh"] should be ["Horse","huh"]
"EEE"" should be "EEE"]
"LL"],h" should be "LL"],"h"
var initial = Array(AnimalName.alKeys)
should be
var initial = Array(AnimalName.keys)
You shouldn't need SO to find and fix typos. Also, try Ctrl+Space after a period, it will propose the appropriate function names and help you avoid misnaming them.
