You use this textfield in the same way as the regular UITextField, through Storyboards or programmatically.

import AutocompleteField

...

let textfield = AutocompleteField(frame: CGRect(x: 20, y: 20, width: 200, height: 40))
textfield.placeholder = "Name"

textfield.suggestions = [
  "George Washington",
  "Thomas Jefferson",
  "John Adams",
  "Theodore Roosevelt",
  "John F. Kennedy",
  "George W. Bush",
]

self.view.addSubview(textfield)

The delimiter can be used to only suggest an autocompletion after a specific character is found in the string. In this example we look for the @ character, and then provide suggestions for email providers.

import AutocompleteField

...

// email textfield autocompleting email providers
let textfield = AutocompleteField(frame: CGRect(x: 20, y: 20, width: 200, height: 40))
textfield.placeholder = "Email"
textfield.keyboardType = .emailAddress

textfield.suggestions = [
  "gmail.com",
  "icloud.com",
  "outlook.com",
]

// add the delimiter
textfield.delimiter = "@"

self.view.addSubview(textfield)
