You can do it this way:

var string = "Apple(100)"                               //"Apple(100)" 
let newStr = string.componentsSeparatedByString("(")    //["Apple", "100)"]
newStr[0]                                               //"Apple"

And if you want to modify whole array then you can use this function:

func seprateString(arr: [String]) -> [String] {
    var newArr = [String]()
    for item in arr {
        let newStr = item.componentsSeparatedByString("(")
        newArr.append(newStr[0])
    }
    return newArr
}


let fruitArr = ["Apple(100)", "Orange(300)", "Pineapple(10)", "Grape(50)", "Banana(1000)"]
let newArrayForFruit = seprateString(fruitArr)

OutPut will be:

["Apple", "Orange", "Pineapple", "Grape", "Banana"]
