it shows 5 errors at this part of code:
func randomFact () -> String {
let unsignedArrayCount = UInt32(factsArray.count)
func randomFact() -> String {
return factsArray[Int((arc4random_uniform(unsignedArrayCount))]
}
1) Expected ',' separator
2)Expected expression in a list of expressions
3)Expected ')' in an expression list
4)Expected expression in a list of expressions
5)Expected ']' in an expression list
// This is the entire code
import Foundation
struct FactBook {
let factsArray = [
"Ckemi",
"Ky eshte nje aplikacion i bere ne gjuhen programuese Swift.",
"Gjuha programuese Swift eshte nje gjuhe moderne,fleksibel dhe e sigurt.",
"Ajo u krijua nga kompania Apple ne vitin 2014 ",
"Ky aplikacion ka si qellim te nxise dhe te promovoje kulturen e qyteteve te Shqiperise",
"Ky projekt eshte konceptuar te vihet ne pune nga Bashkite dhe zonat e tyre perkatese"
]
func randomFact () -> String {
let unsignedArrayCount = UInt32(factsArray.count)
func randomFact() -> String {
return factsArray[Int((arc4random_uniform(unsignedArrayCount))]
}
}
}

Treehouse Moderator 37,862 PointsI think this is what the function is supposed to look like:
func randomFact () -> String {
let unsignedArrayCount = UInt32(factsArray.count)
return factsArray[Int(arc4random_uniform(unsignedArrayCount))]
}
See the difference?

Treehouse Moderator 37,862 PointsTwo things. first you had this line in the middle of the function:
func randomFact() -> String {That will cause an error without a closing brace, which you where missing.
You also had an extra parentheses at the beginning of
arc4random_uniform(unsignedArrayCount). You had two instead of one.
