ChatViewController | 💬 ChatViewController , ChatBar , ImagePicker like Slack | iOS library

I'm very new to Swift, and Instead of just printing the localized description of an error when a user attempts to register for an app, I want to show it in an error label to the user. However, I get the error "Expression is not assignable: function call returns immutable value." I'm not sure what this means or what I should be doing differently in order to show the default description for the error.

I am implementing a UIPageViewController to my app to try to build a UI like Tinder, in which you can swipe left and right to not only like or dislike a person, but to navigate different screens, i.e. chat screen, profile screen, matches screen etc.

In my case, after signing in, a UIPageViewController that contains 4 other UIViewControllers will pop up.

However, the UIPageViewController is modal and doesn't cover the whole screen(as there is a small gap at the top which allows the user to swipe the modal down and away). I tried using code like this:

I ran into a little problem. I am taking a course on iOS development, and I ran into a problem. I'm a perfectionist, and I want to bring applications to perfection, but I can't figure out which way to dig. There is a small black line between the keyboard and the textField that clearly draws attention to itself. How to be? What to do to remove it? Which way should I drip? Maybe this is a problem in Xcode 12.3? Could this be because IQKeyboardManagerSwift is conflicting with the current version of Xcode? The video I watched didn't have this problem.

AppDelegate.swift (Here I call up the keyboard):

I'm building an app using MessageKit.

I added an InputBarItem to the input bar, but it doesn't appear when the view first appears. Only after I pressed "send", the item shows up.

Below is part of the ChatViewController. Any idea why this happens?

Thank you!

I have added chatting/messaging to my application. I can go to a users profile, select message and message them. I also added a tab that show all the users I messaged which is in a table view and you can click a user and see messages between you and them.

The issue happens when I open this tab to see the users Ive messaged when I've messaged more than 10 users. The simulator crashes and I get this error:

"Thread 1: Exception: "Invalid Query. 'in' filters support a maximum of 10 elements in the value array."
here is my code:

Here is the code from sign up view controller

I wanted to save all data from textfields to firebase but after pressing the sign up button it proceeds even if all 3 text fields are empty

import UIKit import Firebase

class SignUpViewController: UIViewController {

Here are all outlets from storyboard

I have tried everything but data is not coming in order , even snapshot is showing data in unordered form

I'm developing chat app. i want to maintain the order of the data so chat must show in order, but its not happening. whenever i send message it placed between the old messages not in the bottom

Here the latest message "what are you doing?"

here's the chat. look where is that latest message "what are you doing?"

my code for observing messages

This is my first trial of programmatically created tableview cells. So maybe I am overseeing some basics. I took over and adapted this piece of code to implement a chat functionality using a tableview. It covers a ChatMessageCell for the tableviewcell and a ChatViewController for the tableview. The ChatMessageCell checks every chat message, wether it is Incoming (user is different from the current user) or Outgoing. If it is an Incoming the cell is pinned to the left on a white background and if it is Outgoing to the right on a green background. The cell size are adjusted to the text of the chat message, so that it shows either on the left or on the right of the screen (like in WhatsApp).

Now the issue: When the tableview is initially built, everything shows up in the right way and the cells is adjusted to the left or to the right. As soon as the user scrolls the tableview, the cells are stretched to take the whole width of the screen, regardless whether they are Incoming or Outgoing. Any hint, what is wrong?

Below is the snippet for the cell creation in the ChatViewController:
