Thanks, It's very helpful to me

one big array for those who don't want indentation

states = ["Alaska", "Alabama", "Arkansas", "American Samoa", "Arizona", "California", "Colorado", "Connecticut", "District of Columbia", "Delaware", "Florida", "Georgia", "Guam", "Hawaii", "Iowa", "Idaho", "Illinois", "Indiana", "Kansas", "Kentucky", "Louisiana", "Massachusetts", "Maryland", "Maine", "Michigan", "Minnesota", "Missouri", "Mississippi", "Montana", "North Carolina", "North Dakota", "Nebraska", "New Hampshire", "New Jersey", "New Mexico", "Nevada", "New York", "Ohio", "Oklahoma", "Oregon", "Pennsylvania", "Puerto Rico", "Rhode Island", "South Carolina", "South Dakota", "Tennessee", "Texas", "Utah", "Virginia", "Virgin Islands", "Vermont", "Washington", "Wisconsin", "West Virginia", "Wyoming"]

Thanks, very helpful

Thank you very much guys! Really helpful! :D

Useful stuff. Thank you.

Thank you to all that shared, it is very helpful.

Thanks for the list......am i really that lazy :)

FYI, because the original post was sorted alphabetically by state code (which itself is likely not what you want), all further iterations of this list are out of order by state name.

let states = [ "AK","AL","AR","AS","AZ","CA","CO","CT","DC","DE","FL","GA","GU","HI","IA","ID","IL","IN","KS","KY","LA","MA","MD","ME","MI","MN","MO","MS","MT","NC","ND","NE","NH","NJ","NM","NV","NY","OH","OK","OR","PA","PR","RI","SC","SD","TN","TX","UT","VA","VI","VT","WA","WI","WV","WY"]

Here's another version I made if anyone wants to use it.
let stateDictionary: [String : String] = [ "Alaska" : "AK", "Alabama" : "AL", "Arkansas" : "AR", "American Samoa" : "AS", "Arizona" : "AZ", "California" : "CA", "Colorado" : "CO", "Connecticut" : "CT", "District of Columbia" : "DC", "Delaware" : "DE", "Florida" : "FL", "Georgia" : "GA", "Guam" : "GU", "Hawaii" : "HI", "Iowa" : "IA", "Idaho" : "ID", "Illinois" : "IL", "Indiana" : "IN", "Kansas" : "KS", "Kentucky" : "KY", "Louisiana" : "LA", "Massachusetts" : "MA", "Maryland" : "MD", "Maine" : "ME", "Michigan" : "MI", "Minnesota" : "MN", "Missouri" : "MO", "Mississippi" : "MS", "Montana" : "MT", "North Carolina" : "NC", "North Dakota" : "ND", "Nebraska" : "NE", "New Hampshire" : "NH", "New Jersey" : "NJ", "New Mexico" : "NM", "Nevada" : "NV", "New York" : "NY", "Ohio" : "OH", "Oklahoma" : "OK", "Oregon" : "OR", "Pennsylvania" : "PA", "Puerto Rico" : "PR", "Rhode Island" : "RI", "South Carolina" : "SC", "South Dakota" : "SD", "Tennessee" : "TN", "Texas" : "TX", "Utah" : "UT", "Virginia" : "VA", "Virgin Islands" : "VI", "Vermont" : "VT", "Washington" : "WA", "Wisconsin" : "WI", "West Virginia" : "WV", "Wyoming" : "WY"]

thanks a lot!

Here's a Swift extension to convert two character state abbreviations to the long-form state name. If there's no valid state, it returns the inputted string:

extension String {
  func longStateName() -> String {
    // check that it's a valid length
    guard self.characters.count == 2 else { return self }
    
    // declare dictionary
    let stateDictionary: [String : String] = [
      "AK" : "Alaska",
      "AL" : "Alabama",
      "AR" : "Arkansas",
      "AS" : "American Samoa",
      "AZ" : "Arizona",
      "CA" : "California",
      "CO" : "Colorado",
      "CT" : "Connecticut",
      "DC" : "District of Columbia",
      "DE" : "Delaware",
      "FL" : "Florida",
      "GA" : "Georgia",
      "GU" : "Guam",
      "HI" : "Hawaii",
      "IA" : "Iowa",
      "ID" : "Idaho",
      "IL" : "Illinois",
      "IN" : "Indiana",
      "KS" : "Kansas",
      "KY" : "Kentucky",
      "LA" : "Louisiana",
      "MA" : "Massachusetts",
      "MD" : "Maryland",
      "ME" : "Maine",
      "MI" : "Michigan",
      "MN" : "Minnesota",
      "MO" : "Missouri",
      "MS" : "Mississippi",
      "MT" : "Montana",
      "NC" : "North Carolina",
      "ND" : " North Dakota",
      "NE" : "Nebraska",
      "NH" : "New Hampshire",
      "NJ" : "New Jersey",
      "NM" : "New Mexico",
      "NV" : "Nevada",
      "NY" : "New York",
      "OH" : "Ohio",
      "OK" : "Oklahoma",
      "OR" : "Oregon",
      "PA" : "Pennsylvania",
      "PR" : "Puerto Rico",
      "RI" : "Rhode Island",
      "SC" : "South Carolina",
      "SD" : "South Dakota",
      "TN" : "Tennessee",
      "TX" : "Texas",
      "UT" : "Utah",
      "VA" : "Virginia",
      "VI" : "Virgin Islands",
      "VT" : "Vermont",
      "WA" : "Washington",
      "WI" : "Wisconsin",
      "WV" : "West Virginia",
      "WY" : "Wyoming"]
    
    // check that key is in the dictionary
    guard stateDictionary[self.uppercased()] != nil else { return self }
    
    // if it's in the dictionary, return the longStateName
    if let longStateName = stateDictionary[self.uppercased()] {
      return longStateName
    }
    
    // If, after all that, there's nothing there, return the string that was fed to the method
    return self
    
  }
}

Usage
// returns "Alaska"
"ak".longStateName()

just thanks again for the help

Thanks for this list!

Just a heads up for non Americans coming across this gist...

Guam, Puerto Rico, Virgin Islands (US), American Samoa are US Territories NOT US States
District of Columbia is a Federal District NOT a State.

The array count for US States should be 50.

Here's a list to find out how well your User Acceptance Testing Dept does their jobs:

let states = [
    "AK - Alaska",
    "AL - Alabama",
    "AR - Arkansas",
    "AS - American Samoa",

    "FP - Fictional Place",
    "GA - Georgia",
    "GU - Guam",
    "HI - Hawaii",
    "IA - Iowa",
    "ID - Idaho",
    "IL - Illinois",
    "IN - Indiana",
    "KS - Kansas",
    "KY - Kentucky",
    "LA - Louisiana",
    "LG - Laguardia",
    "MA - Massachusetts",
    "MD - Maryland",

thank you @brendon @eman. It saved lot of time.

The United States has 50 states, this list is so wrong.

If anyone wants a list that is actually ORDERED -

@objc static let states = ["Alabama", "Alaska", "Arizona", "Arkansas", "California", "Colorado", "Connecticut", "Delaware", "District of Columbia", "Florida", "Georgia", "Hawaii", "Idaho", "Illinois", "Indiana", "Iowa", "Kansas", "Kentucky", "Louisiana", "Maine", "Maryland", "Massachusetts", "Michigan", "Minnesota", "Mississippi", "Missouri", "Montana", "Nebraska", "Nevada", "New Hampshire", "New Jersey", "New Mexico", "New York", "North Carolina", "North Dakota", "Ohio", "Oklahoma", "Oregon", "Pennsylvania", "Rhode Island", "South Carolina", "South Dakota", "Tennessee", "Texas", "Utah", "Vermont", "Virginia", "Washington", "West Virginia", "Wisconsin", "Wyoming"]

I love all of this.

Here's the dictionary with the abbreviations as the values and full names as keys.

let stateDictionary = [
    "Alaska" : "AK",
    "Alabama" : "AL",
    "Arkansas" : "AR",
    "American Samoa" : "AS",
    "Arizona" : "AZ",
    "California" : "CA",
    "Colorado" : "CO",
    "Connecticut" : "CT",
    "District of Columbia" : "DC",
    "Delaware" : "DE",
    "Florida" : "FL",
    "Georgia" : "GA",
    "Guam" : "GU",
    "Hawaii" : "HI",
    "Iowa" : "IA",
    "Idaho" : "ID",
    "Illinois" : "IL",
    "Indiana" : "IN",
    "Kansas" : "KS",
    "Kentucky" : "KY",
    "Louisiana" : "LA",
    "Massachusetts" : "MA",
    "Maryland" : "MD",
    "Maine" : "ME",
    "Michigan" : "MI",
    "Minnesota" : "MN",
    "Missouri" : "MO",
    "Mississippi" : "MS",
    "Montana" : "MT",
    "North Carolina" : "NC",
    "North Dakota" : "ND",
    "Nebraska" : "NE",
    "New Hampshire" : "NH",
    "New Jersey" : "NJ",
    "New Mexico" : "NM",
    "Nevada" : "NV",
    "New York" : "NY",
    "Ohio" : "OH",
    "Oklahoma" : "OK",
    "Oregon" : "OR",

    "Vermont" : "VT",
    "Washington" : "WA",
    "Wisconsin" : "WI",
    "West Virginia" : "WV",
    "Wyoming" : "WY"
  ]

Thanks for this! Y'all are awesome

Here is a dictionary for the state abbreviations and a Bool value:
let states: [String: Bool] = [ "AK": false, "AL": false, "AR": false, "AS": false, "AZ": false, "CA": false, "CO": false, "CT": false, "DC": false, "DE": false, "FL": false, "GA": false, "GU": false, "HI": false, "IA": false, "ID": false, "IL": false, "IN": false, "KS": false, "KY": false, "LA": false, "MA": false, "MD": false, "ME": false, "MI": false, "MN": false, "MO": false, "MS": false, "MT": false, "NC": false, "ND": false, "NE": false, "NH": false, "NJ": false, "NM": false, "NV": false, "NY": false, "OH": false, "OK": false, "OR": false, "PA": false, "PR": false, "RI": false, "SC": false, "SD": false, "TN": false, "TX": false, "UT": false, "VA": false, "VI": false, "VT": false, "WA": false, "WI": false, "WV": false, "WY": false]

Here's a Swift enum, alphabetically sorted by their display name, that includes the 50 states + DC only (so it doesn't include insular areas such as American Samoa, Guam, Puerto Rico, the US Virgin Islands, etc).

Also, it was reviewed for copy, typos and other common mistakes (if you pay attention to the code snippets posted throughout this gist, there're tons of typos 😂 )

Enjoy:

enum AmericanState : String, CaseIterable {
    case alabama            = "AL"
    case alaska             = "AK"
    case arizona            = "AZ"
    case arkansas           = "AR"
    case california         = "CA"
    case colorado           = "CO"
    case connecticut        = "CT"
    case delaware           = "DE"
