Programming in objective-C

   I think the best argument against swift is the plethora of knowledge, tutorials, stackoverflow answers there is for objective-c. When I started learning Unity in 2009, I wanted to use C#. Yet 90 % of all the tutorials, docs, etc.. was in javascript at the time. As I was fairly new to programming then, translating from javascript to C# slowed me down. In hindsight, if I just used javascript I would've progressed much quicker than I did. I think the situation within a year will be different, the iOS community is producing swift tutorials en masse. But I would advice you to start with objective-c.

   The best iOS material is: - Objective-C programming book from big nerd ranch or Programming in Objective-C from Stephen G. Kochan (more in-depth) - cs193p from Stanford (iTunesU) iOS 7 course is objective-c. iOS 8 course (starting in 2015) will be swift.

   After cs193p you should know enough to make apps. If you want to be a great iOS developer, you should also learn: - ios / cocoa design patterns - cocoapods | git - visit http://nshipster.com - visit http://objc.io - Learn from other apps source code: http://maniacdev.com/2010/06/35-open-source-iphone-app-store...

   I highly recommend Programming in Objective-C by Stephen G. Kochan. After that, a free Stanford course on iTunes U is a great resource for wrapping your head around Xcode and iOS development concepts. The course number is CS193p taught by Professor Paul Hegarty. I think the newest semester is called "Developing iOS 7 Apps for iPhone and iPad". iTunes link: https://itunes.apple.com/us/course/developing-ios-7-apps-for...

   Hi, I was developing for Android first and am now doing iOS. I do think that Android is a bigger challenge than iOS, primarily because you have to cater to many different screen sizes. Sure, you have the iPhone 5 which is taller than the other iPhones, but it's more about "clipping" the content for the smaller ones rather than "scaling" the UI up or down for a screen size and Android OS version. It's also heaven how you can have arrays and dictionaries (maps in Java) that contain different data types in Objective-C, even blocks of executable code!

   I used to do just Java and knew no C or C++. Below are the references that best helped me to understand the programming philosophy of Objective-C (it's easy to learn the syntax, but why code is being written a certain way is different).

   Kochan's "Programming in Objective-C" is decent http://www.amazon.com/Programming-Objective-C-Edition-Develo... and I'm a big fan of Erica Sadun's "iOS 5 Developer's Cookbook" http://www.amazon.com/The-iOS-Developers-Cookbook-ebook/dp/B....

   If you've never programmed in C, you may want to seek out a good C tutorial. You can get pretty far in iOS working only with Objective-C objects, but plenty of C-isms leak through so it helps to be familiar with pointers, structs, functions and memory management.

   Objective-C isn't too hard to get up to speed with, especially if you've ever worked in both C and a dynamic language like Python or Ruby. Wrapping your head around Cocoa Touch is a little more daunting, but Sadun's book does a good job of building up the basics step by step, then providing chapters on specific frameworks you can page-fault in as needed.

   Apple recently added "Start Developing iOS Apps Today" https://developer.apple.com/library/ios/#referencelibrary/Ge... which is probably worth taking a look for a beginner.

   For your level of experience I would go would go with Kochan - Programming in Objective-C 4th edition.

   There is also a free course for iPhone programming from Stanford (video lectures).

   MonoTouch is a good alternative if you prefer to use C#, but you will need to pay 99$/year to Apple + 399$ for Monotouch. The good thing is that you can evaluate MonoTouch and pay after you are comfortable with the tool.

   RubyMotion is too young to be used in a large application. Also learning Ruby and Cocoa in the same time can be difficult. I think RubyMotion is a good fit for an experienced Ruby programmer that wants to start coding on iOS. Another potential problem with RubyMotion is that it is currently developed by a single person, which can be problematic on long term.

   That been said, muy advice is to go on the Objective-C route since you are already comfortable with C. Objective-C is a small language and an experienced C programmer can be up to speed in a matter of days.

   The real challenge is in learning the iOS libraries and not the programming language.

   Programming in Objective-C 2.0 from Kochan is an amazing book, that's were I started.

   The Apple's documentation is also pretty damn good and I also use Stackoverflow.com/google a lot when I need to understand something with other prespective
