A tiny wrapper for libmaxminddb which allows you to lookup Geo data by IP address.

NOTE From v0.5.0, MMDB-Swift no longer bundles GeoLite2 database due to the license change. Developers should download the binary version from the Maxmind website.

MMDB-Swift is available through CocoaPods. To install it, simply add the following line to your Podfile:

platform :ios, '8.0'
use_frameworks!
pod "MMDB-Swift"

Then, run the following command:

pod install

To integrate MMDB-Swift into your Xcode project using Carthage, add the following line to your Cartfile:

github "lexrus/MMDB-Swift"

Run carthage update to build the frameworks and drag the built MMDB.framework into your Xcode project.

Package.swift

import PackageDescription

let package = Package(
          name: "YOUR_AWESOME_PROJECT",
       targets: [],
  dependencies: [
                  .Package(
                    url: "https://github.com/lexrus/MMDB-Swift",
               versions: "0.0.1" ..< Version.max
                  )
                ]
)

guard let db = MMDB("PATH_TO_THE_DATABASE") else {
  print("Failed to open DB.")
  return
}
if let country = db.lookup("8.8.4.4") {
  print(country)
}

This outputs:

{
  "continent": {
    "code": "NA",
    "names": {
      "ja": "北アメリカ",
      "en": "North America",
      "ru": "Северная Америка",
      "es": "Norteamérica",
      "de": "Nordamerika",
      "zh-CN": "北美洲",
      "fr": "Amérique du Nord",
      "pt-BR": "América do Norte"
    }
  },
  "isoCode": "US",
  "names": {
    "ja": "アメリカ合衆国",
    "en": "United States",
    "ru": "США",
    "es": "Estados Unidos",
    "de": "USA",
    "zh-CN": "美国",
    "fr": "États-Unis",
    "pt-BR": "Estados Unidos"
  }
}

Notice that country is a struct defined as:

public struct MMDBContinent {
  var code: String?
  var names: [String: String]?
}

public struct MMDBCountry: CustomStringConvertible {
  var continent = MMDBContinent()
  var isoCode = ""
  var names = [String: String]()
  ...
}
