SnapKit | A Swift Autolayout DSL for iOS & OS X

I use UIView as alert view in my app, and i want to show it as banner on top of screen, when device is not connected to internet. So my issue that this view appears under my nav bar, how can i bring it to front ? I've tried to us UIApplication.shared.keyWindow! and add my backgroundView as subview to it, but it causes other issues.

This is my alert view class: I'll provide all class, but my realisation is in show() method.

I faced weird issue while handling UICollectionView

I Created simple custom UICollectionViewCell, which has only one imageView and Label:

There's default placeholder image for Cell's imageView and updating imageView.image from collectionView(_:cellForItemAt:). But When image is set, all subview of cell disappears:

(Cells are not disappear at same time because downloading & setting image is async)

Note: Sample data I used is not wrong (Same data works for TableView in same app)

Why this happens and how can I fix it?

this is Sample data I used:

question: I set several breakpoints inside the function of tableView. However the Xcode didn't execute the code inside the tableView. please tell me how to fix these. I'm new to learn about IOS development and I'm trying to write a demo of Tweeter show page. Looking forward for responses!

Here is code of extension UITablewViewDataSource:

I'm a bit stuck. I have a custom UIView which contains a timer and an UIImageView, that timer fires at a constant interval and changes the image from an array of images. This custom view works fine and is performant when I embed it within any other UIView. It changes images at the prescribed speed and doesn't have any issues. It works as I'd like.

This exact same view however, when placed inside a UITableVieCell that looks like the below, renders only the first image and does not change. I have confirmed that the timer is firing, and the the image view is changing its image under the hood by printing the reference to the UIImageView.image. That is to say, that when embedded within a UITableViewCell, my custom UIView is firing its timer and the UIImageView within this custom view, thinks it is changing its image. This leads me to believe that this is a display issue and not a data setting issue.

As a result, here is what have tried:

1. I've tried wrapping it in DispatchQueue.main.async{}
2. Adding a delegate so that my UIViewController can call tableView.reloadData() when the timer is fired
3. Removing the setter of multiImageView.images on my prepareForReuse

Custom Cell Below

I'm practicing using snapkit to place ui of view. However, I tried many things to move the red box into the safe area under the notch, but I couldn't find a way.

I have created a custom view of checkbox / radio button that animates when checked and unchecked. Problem is when I embed the custom view to a stackView that is .equalSpacing the button cannot be tapped anymore, my guess is the borderView(which has the tap gesture) shrink too small so it cannot be tapped.

Strange though is the borderView can be still be seen even if it really shrunk.

If it is .fillEqually and .fillProportionally it works properly.

I am using SnapKit for arranging constraints.

Let me know if I should paste the whole code here.

I have two UITextFields in UITableViewCell, I want to check when the secondTextField resignFromFirstResponder and both firstTextField and secondTextField empty, It will show a warning label. Please take a look at my code below.

I'm adding a TapGestureRecognizer to an UIImageView at my custom TableViewCell but it's not calling its action. When I tap on the Image, it triggers the didSelectRowAt delegate method of tableview. I am not using any storyboard or .xib. I have done this a thousand times with UI created via .xib with no problems, but I don't understand why programmatically this does not work. Any idea?

At my custom TableViewCell:

I'm having a hard time setting my tableView height according to it's content. My cells have dynamic heights and if I hard code an height for my table view I'm able to see that they are fine. Now my problem is:

• My table view doesn't resize at the correct height according to my cells

• If I do not set a static height for the table view, the cells are not rendered

• BONUS ISSUE: I use SnapKit to make constraints and when I remake constraints to fit my table view height according to content size, it fires viewDidLoad as many times as I have cells*

All things being said here is some code:
