How to change the value of return array from function in swift?

Question

I have return one function:

func abc() -> [Int] {
    return [1,2,3,4]
}

I'm calling this function and trying to modify the return value

abc().sort()

It gives this error:
"Cannot use mutating member on immutable value: 'abc' returns immutable value".

I know in order to change the value inside the function we need to use inout parameter but how to change the value which is returned from the function in swift?

Does this answer your question? Cannot use mutating member on immutable value: function call returns immutable value - not sure why value is immutable (Specifically: Instead of using a mutating functions shuffle(), you can use a variant that returns a shuffled copy shuffled(), similar to sort() vs sorted()) — 0-1

You can only assign the result to a new variable with sorted()

let sortedArray = abc().sorted()
