QUESTION
I am using AORangeSlider which is a subclass of UIControl
that overrides the beginTracking
, continueTracking
and endTracking
methods.
When this control is added to a viewController
, which is presented in iOS 13 using the "cards style", it has very strange behavior. When sliding the control the viewController
will try to swipe down, and it interrupts the slider behavior and makes it unreliable and not work correctly.
If I instead, I present the viewController
with UIModalPresentationFullScreen
the control works correctly.
Is there a way to allow the AORangeSlider/UIControl
to work with the iOS 13 cards style of presentation and not have their touch events conflict?

QUESTION
I have a tableViewCell that has a range slider inside of it. I would like the values from the range slider to be saved to firebase when the user hits handleSave(). I can print out the values when the user slides the range slider inside the tableViewCell, but I cannot save this value from the tableViewCell itself nor can I print the values from the tableViewVC. When I try to print the values from the tableViewVC I don't see anything in my console. But If I were to print them from my tableViewCell itself then it works just fine.
The code that I am using to try and print the values from my tableViewVC is,

To solve this problem you need to use delegation pattern as I did post it.
Delete this line in the handleSave method: let costRangeCell = AgeRangeCell(style: .default, reuseIdentifier: nil)
For minSeekingCost & maxSeekingCost values in the class it must be created additional parameter to hold this values.
When creating AgeRangeCell you are not passing reuse identifier and it can lead slow table view scrolling performance.
- Use MVC and delegation patter. You need to have value holder for your age. Below is example how it can be achieved.
- Build UI using SwiftUI. Together with Combine it allows eliminate delegation pattern.
I did use storyboard for this reason less code needed.

I am trying to create a range slider that has labels representing the sliders handle value. I have the slider enabled but when I try to add the labels to the sliders subview, my app crashes with the error

You want to implement your label tracking inside your custom cell... not in your controller class.
Here's a simple implementation, based on the code you supplied in your question:
