iOS-based devices include the iPhone, iPad and iPod Touch. However, subscribers to the iOS developer program have the tools and options to publish apps for all of the company’s platforms because Apple combined Mac, iOS and WatchOS developer memberships into the Apple Developer Program.
Through Xcode, Apple’s free Interactive Development Environment (IDE), developers can create Mac OS and iOS apps for free. Subscriptions for individual developers, organizations and companies are available for an annual fee of $99, while larger enterprise memberships are priced at $299. There are no usage restrictions, so developers can experiment freely until they have a market-ready product.
Previously, iOS and Mac OS developer subscriptions were separate, requiring individual investment. The combination of platforms into a single membership may encourage Mac OS developers to consider learning and developing in the iOS world, and vice-versa.
