So must you enroll in this system now? The iOS Developer Program prices US$99 per 12 months. For those who’re a brand new comer and simply begin exploring iOS improvement, you’ll be able to depend on the simulator to check out your app first. You’ll be able to wait till you may have a strong plan to distribute your apps on App Retailer earlier than enrolling in this system.

That’s all for as we speak. Take a while to register your developer account and set up Xcode. When you’re prepared, try the subsequent put up and begin to construct your first app.
