FAQ from Swift Interview Assistant?
In Swift, let is used to declare constants, which means their values cannot be changed once they are assigned. On the other hand, var is used to declare variables, which means their values can be changed later. It is recommended to use let whenever possible to avoid accidental modification of values.
Optionals in Swift are used to represent values that may or may not exist. They are denoted by a question mark (?) after the type of variable or constant. If a value exists, it can be unwrapped using '!' operator. However, if an optional is nil, attempting to unwrap it will result in a run-time error.
A closure in Swift is a self-contained block of code that can be passed around and used in your program. It is a function or code block that can capture and store references to any constants and variables from the context in which it is defined. Closures are commonly used for asynchronous operations, like completion handlers and callback functions.
