Write an iPhone application

I need you to make an iOS app for me that meets the following requirements : The desktop version of my website is : [login to view URL] 1- iOS application based on Swift or Objective C (We prefer Swift, see link below) [login to view URL] 2- The backend is developed in Spring MVC and we will provide you with Restful APIs as you requested. 3- The application will be a real estate search based on pictures similar to Instagram/Tinder and will have the following features: - Users can login with their Facebook or LinkedIn account - Users will specify some basic search options such as price levels, the basic search criteria can be changed on the user profile page - The app sends the users' locations to the backend (after authorising by users). - The app sends a http request to the backend and receives houses that match the criteria in JSON format. - Pictures and summary of property features are displayed. Pictures are stored in a bucket on Amazon S3. - Users can like/dislike a picture, and can click on a picture to see details of the property on a different. - Likes, dislikes and geolocations are constantly sent back to the server. - So, in total (to start) we will have four pages (home, property details, user, liked properties). - We have an incomplete prototype (created with JustInMind) which I am happy to share to make everything more clear. 4- Other requirements: We want to be involved in the development process. We will create a repository in our BitBucket or Github account for this project. I look forward to receiving your proposal. This should be done less than 4 weeks, and our budget for this project $700 USD You should be responsible for my needs 8AM to 6 PM GMT
