Swift Requires Chilkat v11.7.0+

Create a vCard (Contact) QR Code

See more QR Code Examples

Demonstrates a QR code that adds a contact to a phone when scanned. The text is a vCard, the standard format for contact details: lines between BEGIN:VCARD and END:VCARD, each ending with CRLF. A vCard is fairly long, so the symbol is larger than one holding a web address. Leave out the fields that are not needed to keep it small. Swift

func chilkatTest() {
    var success: Bool = false

    //  This example requires the Chilkat API to have been previously unlocked.
    //  See Global Unlock Sample for sample code.

    //  The second argument of AppendLine is cktrue to end each line with CRLF.
    let sbCard = CkoStringBuilder()!
    sbCard.appendLine(str: "BEGIN:VCARD", crlf: true)
    sbCard.appendLine(str: "VERSION:3.0", crlf: true)
    sbCard.appendLine(str: "N:Smith;Alex;;;", crlf: true)
    sbCard.appendLine(str: "FN:Alex Smith", crlf: true)
    sbCard.appendLine(str: "ORG:Example Company", crlf: true)
    sbCard.appendLine(str: "TITLE:Sales Manager", crlf: true)
