/**
 * switch 开关选择器
 * @description 选择开关一般用于只有两个选择，且只能选其一的场景。
 * @tutorial https://www.uviewui.com/components/switch.html
 * @property {Boolean} loading 是否处于加载中（默认false）
 * @property {Boolean} disabled 是否禁用（默认false）
 * @property {String Number} size 开关尺寸，单位rpx（默认50）
 * @property {String} active-color 打开时的背景色（默认#2979ff）
 * @property {Boolean} inactive-color 关闭时的背景色（默认#ffffff）
 * @property {Boolean | Number | String} active-value 打开选择器时通过change事件发出的值（默认true）
 * @property {Boolean | Number | String} inactive-value 关闭选择器时通过change事件发出的值（默认false）
 * @event {Function} change 在switch打开或关闭时触发
 * @example <u-switch v-model="checked" active-color="red" inactive-color="#eee"></u-switch>
