I am trying to validate an email field using Regex in SwiftUI-CodePudding

I am simply trying to validate an email using an expression. I have created a Struct that I use for my form fields.

 let emailRegEx = "[A-ZO-9a-z._% -] @[A-Za-zO-9.-J |l.[A-Za-z]{2,64}"
    var isEmailValid: Bool {
        !email.isEmpty &&
        if email.ranges(of: emailRegEx, options: .regularExpression) == nil {
            return self
        }
    }

It keeps throwing this error...Cannot infer contextual base in reference to member 'regularExpression', and Expected expression after operator, lastly Extra argument 'options' in call.

CodePudding user response：

Your if is in the wrong place, and .ranges should be .range.

Assuming your emailRegEx is correct, try this:

var isEmailValid: Bool = !email.isEmpty && (email.range(of: emailRegEx, options: .regularExpression) != nil)

Using a computed var, use this:

var isEmailValid: Bool {
    !email.isEmpty && (email.range(of: emailRegEx, options: .regularExpression) != nil)
}

You could also try this regex for email:

let emailRegEx = #"^\S @\S \.\S $"#

let emailRegEx = #"^[a-zA-Z0-9.!#$%&’* /=?^_`{|}~-] @[a-zA-Z0-9-] (?:\.[a-zA-Z0-9-] )*$"#
