how to store json object in a variable and use globally in other functions in swift -

var drivers : nsarray?

func loaddriversrest()  {            restapimanager.sharedinstance.getdriverlist{ json in             var drivers = json             println(drivers.description)      } 

func getdriverfromid(id: int?) -> string {

    if id == nil {         return "no driver assigned"     }     else{         drivers.["name"] as! string      }     return "test" } 

i don't know want do, there lot of options. can use nsuserdefaults(). did in case user's domains:

private let domain_prefix = "domains_" private let domain_delimiter = "|" private let defaults: nsuserdefaults  init() {     defaults = nsuserdefaults.standarduserdefaults() }  func getdomains(user: string) -> [string] {     if let domains = defaults.valueforkey("\(domain_prefix)\(user)") as? string {         return domains.componentsseparatedbystring(domain_delimiter)     }     return [string]() }  func savedomains(domains : [string], user: string) {     defaults.setvalue(domain_delimiter.join(domains), forkey: "\(domain_prefix)\(user)")     defaults.synchronize() } 

you can save drivers in save way.
