Swift3.0を使って簡単なiPhoneアプリを作ってみます
初心者向け）Swift3.0で簡単なiPhoneアプリを作ってみるで作ったシンプルなSwift3.0アプリでビーコンを検出してみます
#1. ビーコンを用意します
- ビーコンを用意し、UUID、major、minor値を確認します
- 手近にビーコンがない場合、iPhoneやMacbookをビーコンにすることができます
- Macbookからビーコンを発信する方法→SwiftとiBeaconを使ってお母さんが自分の部屋に近づいて来た事を警告するアプリをつくる
- iPhoneからビーコンを発信する方法→手軽にビーコンの動作を体験できる「Beacon入門」アプリが登場！
#2. アプリを用意します
- ビーコンを受信するアプリを作成します
- XcodeでSwiftアプリを用意します
- ラベルを２つ、ボタンを２つ用意します
- ViewController.swiftに下記のコードをコピペします

- 使用するビーコンのUUID/Major/Minorを上記のViewController.swiftのUUIDリストと置き換えます
- 上記のViewController.swiftのlabel1、label2、button1、button2を、用意したラベル（ｘ２）、ボタン（ｘ２）と置き換えて接続し直します
- 位置情報を使用可能にするため、ナビゲーターで「info.plist」を選択し、
- Swift3であれば： 「Privacy - Location Always Usage Description」を追加します
- Swift4であれば： 「Privacy - Location Always and When In Use Usage Description」と[Privacy - Location When In Use Usage Description」を追加します
#4. iPhoneで確認します
- iPhoneにデプロイし、稼働を確認します
#次のステップ
