Edit Contact Field

Scriptable
2

The below script would do it but unfortunately, Scriptable does not have permission to access the note field on iOS 13. The notes of a custom have become a field that Apple needs to approve in order for apps to use it. I will send a request to use it but I think the chances are slim that Scriptable will be allowed to use it.

let containers = await ContactsContainer.all()
let contacts = await Contact.all(containers)
contacts.sort((a, b) => {
  return displayName(b) < displayName(a)
})
let table = new UITable()
for (contact of contacts) {
  let name = displayName(contact)
  let row = new UITableRow()
  row.dismissOnSelect = true
  row.onSelect = (idx) => {
    let c = contacts[idx]
    edit(c)
  }
  row.addText(name)
  table.addRow(row)
}
table.present()

async function edit(contact) {
  let alert = new Alert()
  alert.title = "Enter Note"
  alert.addTextField("Note", contact.note)
  alert.addAction("Save")
  alert.addCancelAction("Cancel")
  let idx = await alert.presentAlert()
  if (idx != -1) {
    let note = alert.textFieldValue(0)
    log(contact.givenName)
    log(note)
    contact.note = note
    Contact.update(contact)
    Contact.persistChanges()
  }
}

function displayName(contact) {
  return contact.givenName
    + " "
    + contact.familyName
}
