如何显示变化的文本（在带有Swift的Xcode中）？

Question

I just started with swift and Xcode and have been working on an app. Right I have no idea how to print a variable in the UI. I understand how to use Labels for static text but need to print numbers that are going to vary based on user input.

Answer 1

You can use string interpolation to create strings from numbers. Then assign to your label.

var myNum: Int = 5
var myString = "The number is \(myNum)"
myLabel.text = myString
