I am a web developer looking to get started with apps for iPhone and iPad.
I have only an iPad Air 16GB. Can I install Xcode 5 and iOS SDK in the iPad for testing, while I code using a Windows PC?
You cannot install Xcode on iPad Air. You need to have a Mac to develop for iOS devices using Xcode and iOS SDK.
You can, but you'll need an OS X machine running and connected to the Internet in order to compile the builds for your iPad.
This is exactly how the Dringend app works. It runs on your iPad as a slimmed-down 3rd-party Xcode replacement (it even understands
.xcodeproj files!), and uses Xcode via a remote OS X host to do the dirty-work.
I thought I read something somewhere about another start-up working towards a product with the same premise, but provides the OS X build-machines as a paid service— I'll update this if I find their name. Until then, there's always OS X hosting.
