Hello Readers,

These are some of the custom checkers to detect

• iPhone
• Current IOS Version
• Email Validation
• Phone Number Validation

For iPhone 4 and 4s :-

func isIPHONE4() -> Bool{
        let screenSize: CGRect = UIScreen.mainScreen().nativeBounds
        return screenSize.height == 960 ?true:false
    }

For iPhone 5 , 5c and 5s :-

func isIPHONE5() -> Bool{
        let screenSize: CGRect = UIScreen.mainScreen().nativeBounds
        return screenSize.height == 1136 ?true:false
    }

For iPhone 6 :-

func isIPHONE6() -> Bool{
        let screenSize: CGRect = UIScreen.mainScreen().nativeBounds
        return screenSize.height == 1334 ?true:false
    }

For iPhone 6+ :-

func isIPHONE6Plus() -> Bool{
        let screenSize: CGRect = UIScreen.mainScreen().nativeBounds
        return screenSize.height == 2208 ?true:false
    }

For IOS Version :-

func getCurrentOS() -> NSString{
        return UIDevice.currentDevice().systemVersion
    }

For Email Validation :-

func isValidEmail(testStr:String) -> Bool {
        // println("validate calendar: \(testStr)")
        let emailRegEx = "[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?"

        let emailTest = NSPredicate(format:"SELF MATCHES %@", emailRegEx)
        return emailTest.evaluateWithObject(testStr)
    }

*For Phone Number Validation :- *

func isPhoneNumbervalidate(value: String) -> Bool {
        let PHONE_REGEX = "^((\\+)|(00))[0-9]{6,14}$"
        var phoneTest = NSPredicate(format: "SELF MATCHES %@", PHONE_REGEX)
        var result =  phoneTest.evaluateWithObject(value)
        return result
    }

For iPad

func isIPAD() -> Bool{
        return UIDevice.currentDevice().userInterfaceIdiom == .Pad ?true:false
    }
