Mailcheck - Swift

The Swift library that suggests a right domain when your users misspell it in an email address. See the original at https://github.com/mailcheck/mailcheck.

When your user types in "[email protected]", Mailcheck will suggest "[email protected]".

Mailcheck will offer up suggestions for top level domains too, and suggest ".com" when a user types in "[email protected]".

Usage

import MailcheckSwift
let result: MailcheckSuggestion? = Mailcheck.suggest("[email protected]")

Result will contain nil if the domain appears to be valid. Otherwise the suggestion will be a MailcheckSuggestion struct that will contain the following fields:

address: String //e.g. "test"
domain: String  //e.g. "hotmail.com",
full: String    //e.g "[email protected]"

Customize maximum edit distance

You can customize the maximum edit distance. For instance with a threshold of 2:

Mailcheck.threshold = 2
Mailcheck.check("[email protected]")

will return a suggestion of "[email protected]". With a threshold of 1 no suggestion would be returned for this case. The default value is 3.

Checking if an e-mail is valid

Checks to see if an e-mail is valid format while also returning a suggestion

import MailcheckSwift
let result = Mailcheck.check("[email protected]")

Result will be a MailcheckResult struct with the following fields

valid: Bool //true or false
suggestion: MailcheckSuggestion? // e.g. MailcheckSuggestion(address: "test", domain: "hotmail.com", full: "[email protected]")

Checking against additional domains

Supply your own domain lists:

let result: MailcheckResult = Mailcheck.check("[email protected]", domains: ["mydomain.co"], topLevelDomains: ["co"])

Or add to the default list:

let result: MailcheckResult = Mailcheck.check:@"[email protected]" extraDomains:["mydomain.co"] extraTopLevelDomains:["co"]];
