Sometimes the simplest things are difficult and looking around at the answers for creating a Text area using Sweet Alert is complex. but I found a simple answer!!!
swal({
title: 'Input something',
input: 'textarea'
}).then(function(result) {
if (result.value) {
swal(result.value)
}
})
If this is not enough try this as it shows a variable that is editable using a text box
