Any opinions for which are quicker or more useful to learn? For anyone who's trying to be on an iOS team, which are you picking so that we can know the same language?
I used Swift when developing the ACES app for iOS. Swift is a newer language and so I definitely think it's worth learning over Objective-C. Also, I didn't find it completely overwhelming to learn and in terms of syntax, it's fairly similar to Java.
I think you should go with Swift -- it's the future!
Objective c is a pain to work with IMO, so I would go with swift.
