ContainerView | Using Container View in iOS with Swift | iOS library

I am trying to show HeaderView in my UICollectionView class and I use UICollectionReusableView class for that.

Actually I am showing HeaderView in my CollectionView but It does not reach to safe area.

I use auto layout programmatically and I wrote extension to do that.

Here is my class and extensions that I use in my code:

When I have a custom UIView with overridden init like this:

I'm having the following view hierarchy which has a retain cycle, that's the simplest I could make to reproduce the issue. All viewmodels and properties has to stay as they are needed in the original solution:

Subview added programmatically to containerView ( UIView, which is connected with @IBOutlet on storyboard ) inside presented HistogramViewController (ViewController) is out of proper layout.

I have 2 Controllers: MainVC and SideMenuVC.

I wanted to modify MainVC using SideMenuVC, so created delegate of SideMenuVC ( as well, there's Emdebed segue "name..." to "Side Menu View Controller" on storyboard because MainViewController has subView, which contains ContainerView - this container is our SideMenuVC. And this delegate works as he should.

However, due to logic in the app, I also need to send data from MAINVC to SIDEMENUVC.

So i did the same - created another delegate of second VC... But I turned out, MainViewControllerDelegate is not responding in SideMenuViewController. And i'm absolutely clueless...

Yes, i do implement necessary protocols in both classes, in extension!

MainViewController + MainViewControllerDelegate

I have created containerView which contain tableViewController. The main issue, when user click on information, tableViewController must show the information which user clicked.

it show the information when I use present(<#T##UIViewController#>, animated: <#T##Bool#>, completion: <#T##(() -> Void)?#>) but doesnt work if I call self.navigationController?.pushViewController

the main issue is when I make vc.info = info it doesnt work, the info has value but using injection the value in another class is nil.

Here is my code:

I'm following this tutorial, specifically the django-filter-backend section.

I am unable to get this to work. My goal is to retrieve a list of "containers" that have the "in_use" field set to True, but it keeps returning all the records in the table. I can't see what I am missing. I have added django-filters to my installed apps list and also added this to my REST_FRAMEWORK block:

I've 2 NavigationView in a screen. When I tap a Go To ChildView item on list, I want to navigate in Parent Navigation. When I tap a one of other items on list, I want to navigate in Container Navigation

How can I push a view to selected NavigationView ? I want to decide from which navigation to push the view.

Parent View

To me it looks like the safe area of a view is not updated after the owning view controller's .viewWillDisappear() method is called.

Is this intended or a bug in the framework?

The issue is easily visualised by creating a custom UIViewControllerTransitioningDelegate that animates a smaller view in one view controller, to full screen size in another (constrained to safe areas). Then the safe area will expand as the present animation goes on (as expected), but will not shrink as the dismiss animation goes on (not expected!). The expected behaviour would be that the safe area expands during the present animation, and shrinks during the dismiss animation.

The gif below shows the unexpected behaviour. The grey area of the presented view controller is the safe area.

Below is the code I used to visualise this problem. ViewController.swift presents MyViewController.swift using FullScreenTransitionManager.swift
