CityPicker | city selection , positioning , search and right-hand letter | RecyclerView library

I'm working with a profile registration view controller, I want to update the title of my UIButton when the user picks the city from the UIPickerController. The title from the button is not updating after the user picks the city.

I try using DispatchQueue.main.async and is not working as well I'm trying to update didSet after dismissing the view from where I present the city picker. When I run my code the value is giving the correct title but is not updating and reloading the data from my view.

First View

I'm using a grid with nested grids to render a form. For some of the entries, I can tap on any area in the entry and it brings up the keyboard. For others, I have to tap on the left side to bring up the keyboard, as shown on the yellow highlighted entry in the image. I've tried placing the grids as children of a stacklayout instead, changing the keyboard type to not be numeric, set horizontal options, set width request. The only thing that works is when I put the nested grid in its own parent with no other children. Not sure what I'm doing wrong. I'm trying to avoid setting a tap gesture recognizer for the whole grid.

Here's my code:

I have been stuck on this problem for a few days now. I have an image view set as invisible until the long press gesture is triggered. However, I can not wrap my head around on how to make the UIImageView to become visible after such. This is within a Cell in tableView. I have used reloadData(), but the issue is the table loses its place. It scrolls upwards by the time you release your finger. The long gesture triggers a boolean on the database side that toggles saveShow. When data is loaded, the query checks and displays the UIImageView if true. So I believe I would have to reload the data since it is based on the query..? Any help will be greatly appreciated!

I’m very new to Swift and Xcode and I’ve built a simple two storyboard app which has a welcome screen and a button that triggers a seque to second storyboard (for which I have created its own class based on UIVIewController. Second storyboard has a couple of UIPickerView objects a and a couple of UIDatePickerView objects and a button. I have some basic actions under the didSelectRow function. However when I build and run the app I get an odd and seemingly random bevahiour where selecting something in the first picker view takes me back to the welcome screen (an unwind seque?). I haven’t put in any code to do that! Any ideas?

I have set a picker view like the picture above, as we can see, at the starting point after the view controller appears, the selection will automatically show the first string on the list (London). but I want when the view appears for the first time, it will show string selection of the middle of the list, like the picture below

here is the code I use

I have two JSON Url. want to parse between two UIPickerView. one UIPickerView for Country, and another one for the city. I have been able to parse JSON in first UIPickerView of Country, in here data is coming perfectly. but I got a thread message in DidSelectRow func when clicking UIPickerView of the city. please try to solve this problem

here is my code.

Salutations,

So I have a pickerView in my main ViewController, and in my ViewControllerTwo I have a singular mapKitView. My issue is that when I am trying to segue by clicking my button, my application crashes and throws an exception. Simply an NSException, this of course does not give me much.

The way I handle my segue is that I created one by manually dragging one from VC1 to VC2 and gave it the identifier of "viewMapSegue", then I also gave my button a tag of 1 as that is how I did a previous exercise and figured that by doing it this way I can ensure that the values are set to what I need at the time of the segue and not after.

All that being said, I am uncertain where I have erred. I know that if I use my VC2 code on its own with some hardcoded lat/long values that it runs fine and shows me the location I inputted. Code is below:
