KeyboardViewController | This is a class | Keyboard library

Before you rip my head off and set it on fire, I know questions like this have already been asked but they all refer to single buttons. I have a collectionView. I'm asking this question after carefully reading all the other questions and trying to combine their solutions together.

I'm creating a keyboard extension with a collectionview. In my collectionView I have custom cells and in their class I placed a button. I want to add a target to each button in the collection view. I know I could use the selectItemAtIndexRow function and ignore the buttoms but I need to handle the touchUpInside and touchDown events (because when I type with y keyboard it's super slow) and I haven't found a way to do it with collectionView cells (if something exists let me know). In order to escape this problem, I thought the best solution could have been adding a button to my cell's class and add the actions I wanted to it, but I found multiple prooblems doing so.

1. I have the classic keyboardViewController you get by creating a new keyboard target where I placed a view (which is the view containing the collectionView).

2. I have a custom view class which contains the collection view

3. I have a custom collectionview cell class

Here I programmatically created my collectionView.

I'm building a keyboard Extension using collectionviews. I want the cells to change color based on the device theme (light/dark). At the moment, when I set the color scheme for my collectionview cells they don't work. I'm marking the problematic parts of my code with a "///" comment.

I found this RayWenderlich project and I liked how they handled the color changing stuff so I copied it.

I have 3 classes:

1. KeyboardViewController
2. Custom View containing keyboard buttons
3. Custom collectionview cells

Overview:
I'm building a keyboard extension and I want it to work both on iPhone and iPad. However, when I run it on iPad it is smaller in width: it's like it cuts off a piece of the view There's no way to adjust it... Here's a picture:

What I'm doing:
First of all I added to my project the keyboard target. Then I created in it a xib file. His file owner is the KeyboardViewController. Inside of this xib view I put another view and I constrained it to containing view (not safe area, I tried it as well but it didn't work). Since it didn't work, I tried setting the constraints programmatically but it still didn't work. Furthermore, to set my keyboard's height I put the following code inside of my viewDidLoad:

Overview
I created a custom view class and an associated nib. When I try to load it in another view controller, it loads it but the constraints are removed.

What I found
Before marking this as a duplicate... I read plenty of questions on StackOverflow of people having the same issues but the ones in swift were either unanswered either non-working. I tried everything.

What I'm doing
I have a view controller (which happens to be a keyboardviewcntroller but on a regular one I still have the problem) with an associated nib and a custom uiView with its associated nib.

• KeyboardViewController:
  I associated with my Keyboard view controller a zip file. His file owner is KeyboardViewController.
  In my KeyboardViewController I have the basic code you get by creating a keyboard target and then I added the custom view outlet before the viewDidLoad
  @IBOutlet weak var vieww: Custom!
  and inside of my viewDidLoad I loaded my nib

Overview
I'm trying tot understand app groups so that I can pass data and variables from my main app to my extension and viceversa.

What I found
It's very hard for me to understand a few concepts because all I could find were other SO questions that only showed how to store and retrieve data.
I even watched this tutorial (and read some more on medium) but I'm still confused.

What I'm doing
First of all I enabled app groups both in my container app and my app extension and i set the app group name to group.grop.

I have 3 files:

1. Shared.swift
2. KeyboardViewController
3. ViewController

In my Shared.swift file I put the following code:

I'm building a keyboard extension.
In my program I have a view controller(1) and a view(2) class which I use for a xib file .

I everyone,

I'm facing a strange issue with UIKit, that I'm not able to reproduce at every app launch. The problem is very simple: I have a main ViewController and a child ViewController that contains a UIScrollView. You can see it as the following image:

My code to add the child controller is pretty simple:

Trying to use CoreData in Keyboard Extension. I guess that database file must be in one place for both - extension and containing app. That place is app group. I made it in Apple account. I set using it in both app and extension (checkbox in Singing and Capabilities). But it s not the same in app and extension or I misunderstood something. Here`s some code.

In my app I made a lazy var to store DB file URL in AppDelegate file:

Can't find any example of using SwiftUI in Keyboard Extension. I create an extension and trying to create simple SwiftUI Button with no action (it just prints debug text). But there is no visible button in Keyboard. Is it possible to create SwiftUI custom keyboard?
