[Solved] Swift – Variable used before being initialized

Swift – Variable used before being initialized

Before we can use a variable in Swift, the variable has to be initialised. There is no default value assigned to a variable when we declare it.

For example, let us declare a variable x to type Int, and print its value, without any initialisation done to x.

main.swift

If we initialize the variable x with some value, then we can use the variable in the rest of the program.

main.swift

In this Swift Tutorial, we learned how to solve the Swift Compiler Error “Variable used before being initialized”.
