>Apple provides Objective-C and Swift to write native iOS apps.

Our developer uses Swift on an old Mac laptop for now.

We will buy a developer's station iMac 27-inch 3.2 Ghz quad-core Intel Core i5 processor soon.

>Cordova allows you to write "hybrid" apps using HTML and JS that target iOS, Android, and other devices. They run in an browser-like container, but have more access to device capabilities than a web app running in the browser.

>You may be able to do some development in Windows, but as far as I know, all of the above require a Mac to compile for iOS.
