Swift Fibonacci what is wrong?

Question

Swift

Good afternoon!
When you run this code, Terminated by signal 11 crashes, what's wrong?
PS just starting in SWIFT

import Foundation

func fibbonachi(_ n: Int...){

    if n.count==0 {
        print(1)
        fibbonachi(0,1)
    }
    else {
        if n[0]==144 {return;}
        print(n[0]+n[1])
        var left = n[0]
        fibbonachi(n[0],left+n[1])
    }
}
fibbonachi()

Answer 1

fibbonachi(n[0],left+n[1])

Yah? The first term of the next value must be the second term of the previous one:
fibbonachi(n[1], left + n[1])
