Develop a social media app using Swift with a user-friendly interface that enables users to create detailed profiles including their interests, age, location, and profile picture. It should allow users to connect with their already existing friends and family via social media handles or phone numbers, and also provide suggestions based on their similar interests. The app should have options for users to share photos, videos, and blog posts, create groups and events, and have a messaging system to privately communicate with other users. It should have robust privacy settings, allowing users to choose what information they want to share with others and the app should also implement a strong system of authentication to avoid any kind of data breach.
