正则表达式可以用于指定格式的判断
- 手机号的判断
- 身份证号的判断
- 手机号码的判断
static func isValidPhoneNumber(_ phoneNumber:String)->Bool{

let CU = "^1(3[0-2]|5[256]|8[56])\\d{8}$" //联通
let CT = "^1((33|53|73|8[09])[0-9]|349)\\d{7}$" //电信
let regextestmobile = NSPredicate(format: "SELF MATCHES %@",mobile)

- 身份证号判断

这两个是个人信息常用到的判断,其中的正则也可根据实际的业务流程做修改,以上都是swift3.0版本的
