Hello, I was wondering how to compare two UIPaths together. Perhaps also find a percentage difference between the two. I was thinking initially of comparing the coordinates of every point. Are there any better solutions? Thank you.

I am trying to change the cell's background color depending on their placement, i would like to create an effect like this This is the code i use func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) { if totalCells % 2 == 0 { cell.backgroundColor = UIColor(red: 200/255.0, green: 200/255.0, blue: 200/255.0, alpha: 1.0) } else { cell.backgroundColor = UIColor.white } } The problem is that the cells are in a scrolling tableview, and that when I scroll, the cells get reused for memory purposes, and the colors start changing incorrectly, like the same colors are ending up next to each other, which is not supposed to happen. I am updating the totalCells Variable whenever I add a cell (inside the cellForRowAt function) How could I fix this? Thank you!

I'm trying to back to my initial view controller, but it wasn't presented if the user was already logged in. So, when the user logs out, i want to go back to the initial view controller. i'm currently using a segue, but that would cause a memory leak if used too much. I can't user an unwind segue since the initial view controller was never presented. How would i do this? Thanks.

I am trying to see if the user is logged in using the userdefaults, and if he is, to display the main view controller. This is the scene delegate code. var window: UIWindow? func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) { if UserDefaults.standard.bool(forKey: "isLoggedIn") && false { let homeViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "MainStoryBoard") as! MainViewController let navigationController = UINavigationController(rootViewController: homeViewController) window?.rootViewController = navigationController } else { let homeViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "InitialViewController") as! InitialViewController let navigationController = UINavigationController(rootViewController: homeViewController) window?.rootViewController = navigationController } window?.makeKeyAndVisible() } This is what it's supposed to look like: However, this is what it looks like : We can see the navigation bar is totally gone. This is how my views look like. I have a tab view controller linked to a navigation view controller linked to the main view controller I would like to present. Thanks!

I am trying to see if the user is already logged in, and if he is, to bring him to a navigation controller, which contains the mainViewController. This is in my scene delegate if UserDefaults.standard.bool(forKey: "isLoggedIn") { let homeViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "MainStoryBoard") as! MainViewController let navigationController = UINavigationController(rootViewController: homeViewController) window.rootViewController = navigationController } This is what it's supposed to look like But, instead, it removes the navigation bar.

I am trying to publish and download images from firebase storage. I publish an Image, and then try to fetch it, which works, but when I try to replace that same image by another one, and then fetch that new image, it still shows me the old image, even though when I look in the database, it shows the new Image and nothing else. There are no errors. This is how I am fetching my image. let storageRef = Storage.storage().reference() let ref = storageRef.child("Profiles/\(UserModel.docId).jpeg")          let placeHolderImage = UIImage(systemName: "person.circle.fill")    profileImage.sd_setImage(with: ref, placeholderImage: placeHolderImage) This is how I am uploading my images let storageRef = Storage.storage().reference() let ref = storageRef.child("Profiles/\(UserModel.docId).jpeg")       let metaData = StorageMetadata() metaData.contentType = "image/jpeg" ref.putData(ImageData, metadata: metaData)

I have a mapkit that shows the user's location on the map. This was working, until I updated my iphone 14 to ios 16.3.1, Now it shows the user's location on New York(because the default location I set is NY) I also have an autocomplete, but since that it thinks my location is in new york, it shows me places that are in new york. This is my viewdidLoad locationManager.delegate = self       locationManager.requestWhenInUseAuthorization() locationManager.requestLocation() locationManager.startUpdatingLocation()       mapView.showsUserLocation = true       let locationSearchTable = storyboard!.instantiateViewController(withIdentifier: "LocationSearchTable") as! LocationSearchTable resultSearchController = UISearchController(searchResultsController: locationSearchTable) resultSearchController?.searchResultsUpdater = locationSearchTable       let searchBar = resultSearchController!.searchBar searchBar.sizeToFit() searchBar.placeholder = "Search for restaurants" navigationItem.titleView = resultSearchController?.searchBar       resultSearchController?.hidesNavigationBarDuringPresentation = false definesPresentationContext = true       locationSearchTable.mapView = mapView       locationSearchTable.handleMapSearchDelegate = self

Hello, I am trying to use the framework googleplaces for my app. However, it keeps throwing this error. Three days ago, this worked, however, I accidentally switched to an old git version without GooglePlaces, and now, it doesn't work anymore. This is my podfile : source 'https://github.com/CocoaPods/Specs.git' platform :ios, '14.0' target 'FirstApp' do  use_frameworks!  pod 'GooglePlaces', '7.3.0'  pod 'FirebaseAuth'  pod 'FirebaseFirestore' end When i remove the googleplaces pod, it works. I tried everything I could find on stackOverflow, like : 1- Uninstalling and clearing cache 2- Making new projects just to test this 3- changing the framework search paths 4- I am opening the .xcworkspace 5- deleting all pods and reinstalling
