Here is the code:
class SearchViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, UITextFieldDelegate {
private let label: UILabel = {
let label = UILabel()
label.text = "Where to?"
label.font = .systemFont(ofSize: 24, weight: .semibold)
return label
}()
private let field: UITextField = {
let field = UITextField()
field.placeholder = "Enter destination"
field.layer.cornerRadius = 9
field.backgroundColor = .tertiarySystemBackground
field.leftView = UIView(frame: CGRect(x: 0, y: 0, width: 10, height: 50))
field.leftViewMode = .always
return field
}()
private let tableView: UITableView = {
let table = UITableView()
table.register(UITableViewCell.self,
forCellReuseIdentifier: "cell")
return table
}()
var locations = [Location]()
override func viewDidLoad() {
view.backgroundColor = .secondarySystemBackground
view.addSubview(label)
view.addSubview(field)
view.addSubview(tableView)
tableView.delegate = self
tableView.dataSource = self
field.delegate
// Do any additional setup after loading the view.
}
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
label.sizeToFit()
label.frame = CGRect(x: 10, y: 10, width: label.frame.size.width, height: label.frame.size.height)
field.frame = CGRect(x: 10, y: 20+label.frame.size.height, width: view.frame.size.width-20, height: 50)
}
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
field.resignFirstResponder()
if let text = field.text, !text.isEmpty {
LocationMananger.shared.findLocation(with: text) { [weak self] location in
}
}
return true
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return locations.count
}
func tableview(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell",
for: indexPath)
cell.textLabel?.text = locations[indexPath.row].title
cell.textLabel?.numberOfLines = 0
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
tableView.deselectRow(at: indexPath, animated: true)
let coordinate = locations[indexPath.row].coordinates
}
}
Please can you help, I'm realitivly new to swift and I need to finish this problem urgently.

So basically I can tell that the images are being saved by the system (it shows it on the debug terminal) however whenever I close, and then reopen the app the images firstly aren't there at all but also whenever I search the address name I saved them as... I have tried diagonsing the problem by changing UUID's, changing PNGs to JPGS - no matter what I do it does not show once the application has closed. I think it might have to do with how the image are .HEIF (apple's standard) but I don't have any concrete evidence to back this up. If anyone can help it would be greatly apperciated.

I'm working on a functionality on my code - where it will add a flag to the map once an image is added to the app (via the second page, not shown) but it just doesn't perform how I want. Basically the photo saving is working perfectly and shows via the terminal where and how something is saving and the flags or pins that are added to the map also do save however just to see the you have to go to the second page (press on it) and come back to page 1 (Map) to see them - I just want to be able to see them from the start of the app. I tried init() { loadSavedImages(for: "") loadSavedImageLocations()
but this doesn't really help much - if anyone can help it would really be apperciated.

This is part of the code from my project - the issue that I am getting is that the bottom sheet when it appears it appears infront of the tabview items - while I want it to appear behind the tabview.

import UIKit

struct ContentView: View {
@State private var mapType: MKMapType = .standard
@State private var selectedTab = 0
@State private var ShowingBottomSheet = false

ZStack(alignment: .topLeading) {
MapView(region: $mapAPI.region, mapType: $mapType, imageLocations: imageLocations,
weatherInfo: $weatherInfo, showWeatherInfo: $showWeatherInfo)

VStack {
HStack {
TextField("Enter an address", text: $text, onCommit: {
fetchLocationInfoFromWikipedia(for: text)
mapAPI.getLocation(address: text, delta: 0.5)
showLocationInfo = true
ShowingBottomSheet.toggle()
// Save the image location
if let location = mapAPI.locations.last?.coordinate {
ImageDataManager.shared.saveImageLocation(location)
}
})
