Change the server your app connects, without any further build or export. Directly from Apple's Settings App.

Most of us, developers struggles while hearing the cursed words "Can you send me an IPA which is looking at my laptop's host? Fast.". That is the time you say unconsciously, "not neat". Wouldn't that be better if you could change the host the app is connecting, by just going to the app settings and select? or type manually?. W'd be great.

The life saver. The force awakener.

You'd better use this only in "Debug" mode. Don't ship your app with this. Then set the DEBUG symbol like told here: http://stackoverflow.com/a/30013587

In any view controller's viewDidAppear method, just add the following. This will create a blue view floating on your app. Like the chat heads of Facebook app.

You are set.

Preferences.setHostView()

This floating blue view always stays on front so you're aware where your app requesting. Any contributions are welcome.
