For ios mobile app which language is best? either objective or swift?

Which language do you know? Objective-C has been around for a very long time and

has the benefit of having some portability and a large base of examples and support

globally. Swift is still relatively new and though it is now open source, is still in a constant

state of change.

Those new to programming, seem to find Swift easier to learn and read. Those with a lot

of programming experience tend to feel Swift is too close to scripting languages in some

ways and more like Java in structure. Personally, I find Swift cumbersome in that it

requires an additional runtime payload and while trying to hold the programmers hand

and avoid errors, it actually makes them far more likely with the implicit and explicit

unwrappings.

If you are just learning, and want to quickly get off the ground with an app, I'd say

learn Swift. You WILL need, C and Objective-C and many other languages if your

goal is to make a career of development but, Swift will get you started.

Objective-C builds on C. Swift takes ideas from a lot of other languages, mostly

scripting languages and goes from there. It means for small projects a lot less

lines of code overall but also a dependence on implementation within the compilers

and frameworks to do anything useful. It is also only compatible with specific versions

of OSX and iOS. Objective-C and C are compatible with ALL versions of OSX and

iOS (depending on xCode version)... So, if you want to support a device running

iOS 6, you cannot use Swift. Anything before OSX 10.9 or iOS 7, no Swift.

ok.. thank you for your reply...
