I am new to coding and need help pulling the value out of my slider functions. Right now I am trying to add two of the sender.values together by updating the outside variable in the slider function. I dont know how to pull the information out of the function. Anything helps! Thanks!
class sbBasicController: UIViewController {
@IBOutlet weak var nutritionNum: UILabel!
@IBOutlet weak var hydrationNum: UILabel!
@IBOutlet weak var basicAvg: UILabel!
// Variables
private var nutritionValue: Float = 0.0
private var hydrationValue: Float = 0.0
//Functions
@IBAction func nutritionScroll(_ sender: UISlider) {
nutritionValue = sender.value
nutritionNum.text = String(format: "%.1f", nutritionValue)
}
@IBAction func hydrationScroll(_ sender: UISlider) {
hydrationValue = sender.value
hydrationNum.text = String(format: "%.1f", hydrationValue)
}
func updateBasic() {
let basics = (nutritionValue + hydrationValue)
print("(basics)")
basicAvg.text = "(basics)"
}
}

So what is not working? You never actually callupdateBasic. Do you need the average (you're not even doing averaging at the moment, just summing the two values) to be displayed whenever one of the two sliders change there value?

Right now it doesn't appear like anything is calling updateBasic() which is why the basicAvg label isn't being updated
The nutritionScroll and hydrationScroll methods should each call updateBasic().
@IBAction func nutritionScroll(_ sender: UISlider) {
nutritionValue = sender.value
nutritionNum.text = String(format: "%.1f", nutritionValue)
updateBasic()
}
Another option would be to add a didSet to each of the nutritionValue and hydrationValue properties.
private var nutritionValue: Float = 0.0 {
didSet {
// You could even update nutritionNum.text here as well
updateBasic()
}
}

you can simply call the updateBasics function in both sliderNutrition& sliderHydration events.
declare the updateBasics function like this:
func updateBasics
{
hydrationNum.text = String(format: "%.1f", sliderHydration.value)
nutritionNum.text = String(format: "%.1f", sliderNutrition.value)
basicAvg.text = sliderNutrition.value+ sliderHydration.value
}
