What is let keyword in swift
In Swift, the let keyword can be used to construct immutable variables. An immutable variable is a constant that can only be initialised once. The keyword let is used to declare a constant value, which means that once you’ve given it an initial value, you won’t be able to change it. The variable var is used to declare the value of a variable. The keywords let and var are used to name variables in Swift. The let keyword declares a constant, which means it can’t be renamed after it’s been formed, but its variable properties can be changed afterwards. The var keyword declares a new variable with the ability to modify its value at any time.
