SwiftUI: Formatting Decimals in Text View
When using the Slider view to select a value in SwiftUI, we often encounter an issue when displaying the value in a Text view. By default, the value is displayed as a decimal, even when a step value of 1 is used. For example, the number 34 appears as 34.000000.
To format the value and display it without the decimal places, we can utilize the specifier parameter when interpolating the value in the Text view. The specifier allows us to use a string format specifier to control the display format.
In this case, we can use the format specifier %.0f to display the value as an integer:
1 | Text("\(age, specifier: "%.0f")") |
Now, the value is shown as 34 instead of 34.000000. The %.0f format specifier ensures that no decimal places are displayed.
By implementing this formatting technique, we can enhance the user experience by presenting the selected value in a clear and concise manner.
