title: Connecting AWS RDS and server instance in iOS app Xcode
body: <p>I am building an app for the first time and it requires a back-end connection with the database. I've established a working EC2 and RDS instance in AWS (also trying out for the first time). I don't know how exactly to establish a connection in Xcode with a .php file, there's a couple missing holes in my knowledge that I hope someone can clear up. Every online resource I've looked up doesn't use the exact stack that I'm using so I get confused as to where to go from here.</p>
  
  <p><strong>How would I go about connecting to my Amazon RDS (mySQL) credentials inside my XCode project? Also would I save a separate .php file with the server connection and insert the URL of the file from my local directory? I know I have an endpoint URL provided by RDS, I'm just confused as to how to go about connecting all of this in order to start the POST/GET requests. There isn't a clear tutorial on this, so hope to get some answers here.</strong> </p>
