I'm developing an app that has accounts with usernames and passwords to log in. So far I have found firebase, which doesn't look bad, but I'd like to know every available option and what they have to offer before committing to one. I was curious if Apple had some sort of kit for developers for a login system. And if not maybe other options for this. Thanks for any help!

I'm developing an app that has accounts with usernames and passwords to log in. So far I have found firebase, which doesn't look bad, but I'd like to know every available option and what they have to offer before committing to one. I was curious if Apple had some sort of kit for developers for a login system. Like CloudKit for example, can CloudKit be used to store log in info and be reached when the user is logging in? And if not maybe other options for this. Thanks for any help!

Given an image selected in a UIImagePickerController and saved as a UIImage, how can I save that image in a core data model using XCode 14 beta? I’ve only found videos from 2 years ago where they make their own persistence file which is outdated. Any help would be greatly appreciated! Thanks.

So I know this is probably a stretch, but is there any way to airdrop an object from core data? From what I understand airdrop is only used with links, but is there a way to convert the data of a core data object into a file, convert the file into a link, send it via airdrop, and convert it back into a file, and then add that object from a file to another user's core data storage? Any help would be greatly appreciated. Thanks!!

I'm currently trying to save a selected image in core data as a type data, but I'm getting an error in the persistence file marked with a comment. I've included my code and any questions I will gladly answer. Thanks for any help!

So I was trying to save an image in core data and created an NSManagedObject Subclass. After doing so I decided I didn't like it so I deleted the files, but now every time I run the project it creates a properties file with an error saying it can't find a UIImage in scope and the file isn't editable so I can't import UIKit. I've tried deleting the file in finder, deleting the whole project and then redownloading it from GitHub, but to no avail. Basically I want it to stop making the subclass every time I run the project. Please help. Thanks!

So I'm looking to add a button to my app that would create and fill a reminder in the user's Reminders app, but I've found that I first need to request access to the user's Reminders app data. I've also found the way to do that has been changed with iOS 17 as explained here: https://developer.apple.com/documentation/eventkit/ekeventstore/4162273-requestfullaccesstoreminders How do I use this function so that the prompt requesting for access to the user's Reminders app pops up at the launch of the app every time unless they've previously given permission? Also what would be the function to create the reminder once I do have permissions? This is the code ChatGPT gave me to do so, but I just keep getting "Failed to create Reminder URL". func createReminder() { let reminderTitle = "Cocktail Groceries" var subtaskStrings: [String] = [] for ingredient in shoppingList { subtaskStrings.append(ingredient) } let subtasks = subtaskStrings.map { (ingredient) -> [String: Any] in return [ "title": ingredient, "completed": false ] } let reminderData: [String: Any] = [ "title": reminderTitle, "subtasks": subtasks ] if let reminderURL = createURL(for: "x-apple-reminder://", with: reminderData) { UIApplication.shared.open(reminderURL) } else { print("Failed to create Reminder URL") } } Also I intend on expanding this function to the notes app. But im taking one step at a time. Any help would be GREATLY appreciated. Thanks!
