Money & Currency
A Money is an struct that represents an amount and an associated currency. Amounts either represent a real value (e.g. -$1927.10, ￥10, £1.56, 0.00kr.) or are unavailable (e.g. have no numerical value).
let NZD = CurrencyManager.shared.get(code: "NZD")! var m = Money(decimal: Decimal(40192.49), currency: NZD) m += Money(float: 5.0, currency: NZD) // m is now 40197.49 let f = MoneyFormatter(currency: NZD) let s = f.format(m) // s is now "$40,197.49"
Extensions to Swift's String struct to provide easier and safer access to substrings (at the expense of performance). Easier - no String.Index manipulation is required, indexes are specified using Int's. Safer - all bounds checking is performed before string manipulation, and therefore no possibility of generating an uncatchable fatal error can occur.
let msg = "My dog has fleas" let c: Character = msg! // c is now "y" var s: String = msg[4...] // s is now "og has fleas" s = msg[7...35] // s is now "has fleas" s = msg.removeSuffix("fleas") // s is now "my dog has "
Extensions to Swift's Data struct to provide Hex encoding and decoding.
let d = Data(hexEncoded: "0fe3a9bc") // d is now 0x0f,0xe3,0xa9,0xbc let s = d.hexEncodedString(options: .upperCase) // s is now "0FE3A9BC"
