let someString = "42222222222"
if let myInteger = Int(someString) {
let myNumber = NSNumber(value:myInteger)
}
Swift 2.0
Use the Int() initialiser like this.
let someString = "42222222222"
if let myInteger = Int(someString) {
let myNumber = NSNumber(integer:myInteger)
print(myNumber)
} else {
print("'\(someString)' did not convert to an Int")
}
