```swift

import SwiftBigInt

func fib(n: BigInteger) -> BigInteger {

    if n < 2 {

        return n

    }

    var fibPrev = BigInteger(int: 1)

    var fib = BigInteger(int: 1)

    var num = BigInteger(int: 2)

    repeat {

        (fibPrev, fib) = (fib, fib + fibPrev)

        num += 1

    } while num < n

    return fib

}

print(fib(BigInteger(int: 100000)))

```
