if (r.value) {

must be if ('value' in r) {

I'm editing existing values using $prompt and want to support empty values as well. Due to the current implementation, I get an error when the user wants to remove the existing value.
In this case I cannot distinguish between an error or just an empty value.

To workaround this, l I've copied the $prompt method and added a modified version to my project.

This is the code I use:

import Vue from "vue";
import VueSimpleAlert from "vue-simple-alert";
import Swal from "sweetalert2";

Vue.prototype.$prompt = function (message, defaultText, title, type, options) {
    return new Promise(function (resolve, reject) {
        var mixedOptions = Object.assign(Object.assign({}, VueSimpleAlert.globalOptions), options);
        mixedOptions.title = title || mixedOptions.title;
        mixedOptions.inputValue = defaultText;
        mixedOptions.html = message || mixedOptions.text;
        mixedOptions.type = type || mixedOptions.type;
        mixedOptions.showCancelButton = true;
        mixedOptions.input = mixedOptions.input || "text";

        Swal.fire(mixedOptions)
            .then(function (r) {
                resolve(r.value);
            })
            .catch(function (e) {
                console.log("Error $trompt", e);
                return reject();
            });
    });
};
