You have now completed the entire process of building an app and submitting it to the App Store. If you have gone from beginning to end, congratulate yourself, because it is genuinely a big feat.
At this point, all you can do is wait for Apple to review your project. The next week or so will be the most nerve-wracking (at least it was for me). Don't worry if your app gets rejected, because it happens to the most experienced of developers and is often fixable. Apps can be rejected for minor reasons that are easy to fix; however, you do not want to work for months on a project and miss something big that Apple will never approve. So, do your research regarding what is and is not acceptable to Apple. When you submit your apps to the App Store, please reach out to me on Twitter (@thedevme) to let me know—I would love to see what you have built.
