AvatarImageView | -- - Use https : //github.com/neone/NDAvatarApp | iOS library

I’m trying to get information from the GitHub API using MVP.
Search for GitHub users by the characters you enter in the UISearchBar.
I was able to pass the information from the Model to the Presenter as a result, but the following part of the Presenter shows an error.

I have some cells in my collectionView, oriented vertically.
Every cell has got an image in it's left part and that image loads correctly.
But after I added a rounded top-right corner to the image doesn't automatically load when the screen in on.
Here is the method that is being called in cellForItemAt

Project Level :

I am currently making a program in swift that involves a screen of choosing an image from either camera or photo library using action sheet. This is fully functional however I would like to be able to choose a square section from the selected image, similar to apple default apps. How can I implement this? Here is my functional code:

I'm trying to implement this design but all solutions I have browsed won't work and from what I understand it could be because of the spacing between the cells and the UITableView.
Here's the design:

So basically what I'm trying to achieve is to have shadows from all 4 sides as well as some spacing between each cell and the following cell. Thanks

Edit: Here's the code I tried.

I want to create Custom Image View for avatars which can work in two modes:

1. If android:src is empty display circle with first letter of name
2. Else display circle avatar

At now if I use android:src my drawable is not in center, how can i make central crop of it?

Example

Here is code of custom view:

I am using a UIImagePickerController in my program and it is effectively changing the image of an imageview i have added. However, whenever I restart this app and come back to the home screen, it is automatically resetting to the default image I had it to before, rather than the user selected image. How can I make it so that it records which image was last used, and reloads it every time the program starts?

I am making a view for conversation between two people. I have used UICollectionView with custom cell and using a flag based upon which I decide whether the message should be aligned towards left or right. The constraints work correctly if I use only a single direction of alignment, it even works correctly with condition based alignment unless number of messages in UICollectionView is less than four. So I know that constraints are not wrong. But as soon as I add the fourth message the alignment and sequence of previous cell contents and cells gets disturbed. Attached screenshot shows the problem.

correct behaviour with 3 or less messages

wrong behaviour when 4 or more messages added

I'm having some difficulty and haven't been able to find any solutions within other SO answers...

I have two tableviews within one viewcontroller, and they both work fine switching back and forth, but only if one of them is loaded first.

When I try to load the other one first (which I'll want to do sometimes depending on the user's path to the table), the app crashes with the error "unable to dequeue a cell with identifier customMessageCell - must register a nib or a class for the identifier or connect a prototype cell in a storyboard"

I've registered the nib for both custom cells in the viewDidLoad, identified the prototype cells in the storyboard, etc. Basically, all the usual solutions when I searched this error

Within my viewDidLoad:
