It's not a bug, it's a feature. ;-) The WiFi payload can handle clear text and hex-formatted passwords. Passwords in HEX format have to be escaped, by wrapping them between double quotes. By default QRCoder checks the password and if the password string is in HEX format, it adds the double quotes. Unfortunately iOS struggles with this format. To avoid adding the quotes automatically, just set the escapeHexStrings parameter of the WiFi PayloadGenerator to false as explained in the documentation: https://github.com/codebude/QRCoder/wiki/Advanced-usage---Payload-generators#321-wifi
