WeSplit

Simple check splitting app: project from Hacking with Swift, this is my first iOS application.

Demo

Notes

Under the hood:

These are the variables that allow the app to save user inputs to be used in the later calculations along with default values and available tipping options.

    @State private var checkAmount = ""
    @State private var numberOfPeople = 0
    @State private var tipPercent = 2
    
    let tipOptions = [0, 10, 15, 20, 25]

The function below takes the variables above and depending on input, calculates a split check including tip or just a tip, it is then returned to be displayed using calculatedCost("total") for the total amount per person, or calculatedCost("tip") to get only the tip amount.

    func calculatedCost(_ type: String) -> Double {
        let people = Double(numberOfPeople + 2)
        let tip = Double(tipOptions[tipPercent]) / 100
        let amount = Double(checkAmount) ?? 0
        if type == "total" {
            return amount * (1 + tip) / people
        } else if type == "tip" {
            return amount * tip
        }
        return 0
    }
