title: Share datas between two apps with iOS 7 App Groups (using NSUserDefaults)
body: <p>Can I use method of NSUserDefaults "initWithSuitName:" in iOS 7 to share preferences between two apps with same bundle seed ID (com.my_company)?</p>
  
  <p>On iOS 8.0 and later works fine, but on iOS 7.x not working, though documentation says: "Available in iOS 7.0 and later".</p>
  
  <pre><code>- (instancetype)initWithSuiteName:(NSString *)suitename NS_AVAILABLE(10_9, 7_0) NS_DESIGNATED_INITIALIZER;
  </code></pre>
  
  <p>What am I doing wrong? Thanks!</p>
