Swift: Convert String to NSMutableArray [duplicate]

Question

I want to convert following String to NSMuableArray.

var components: String = "library/book/science"

For example, I want to perform the following objective c code in Swift

NSArray *componentsArray = [@"library/book/science" componentsSeparatedByString:@"/"];

NSMutableArray *componentsMutableArray = [[NSMutableArray alloc] initWithArray:componentsArray];
[componentsMutableArray addObject:@"astronomy"];

change String to NSString and you can keep using same functions. — Shamas S

Here is your working swift code:

var components: String = "library/bool/science"

let componentsArray = components.componentsSeparatedByString("/")     //["library", "bool", "science"]

let componentsMutableArray = NSMutableArray(array: componentsArray)   //["library", "bool", "science"]

componentsMutableArray.addObject("astronomy")                         //["library", "bool", "science", "astronomy"]

var components: String = "library/book/science"
var componentMutableArray = components.componentsSeparatedByString("/")
componentMutableArray.append("astronomy")

You need to use NSString in order to call the componentsSeparatedByString function that will split your text into an array based on the separator of your choice.

let theString = NSString(string: "library/book/science")
let components = theString.componentsSeparatedByString("/")
