Adyen Test Card Numbers
These cards are only valid on our TEST system and they will never involve any actual transaction or transfer of funds. The TEST card numbers will not work on the Adyen LIVE Platform.

For all cards use the following expiration and CVV2/CVC2/or CID for Amex. 

For all cards:

Expiration Dates	  CVV2 / CVC3	CID (American Express)
08/2018 OR 10/2020	737	7373

Season's Greetings, NSHipsters!

As the year winds down, and we take a moment to reflect on our experiences over the past months, one thing is clear: 2014 has been an incredible year professionally for Apple developers. So much has happened in such a short timespan, and yet it's hard to remember our relationship to Objective-C before Swift, or what APIs could have captivated our imagination as much as iOS 8 or WatchKit.

It's an NSHipster tradition to ask you, dear readers, to send in your favorite tips and tricks from the past year for publication over the New Year's holiday. This year, with the deluge of new developments—both from Cupertino and the community at large—there should be no shortage of interesting tidbits to share.

Submit your favorite piece of Swift or Objective-C trivia, framework arcana, hidden Xcode feature, or anything else you think is cool, and you could have it featured in the year-end blowout article. Just comment on this gist below!

If you're wondering about what to post, look to
