How to see the app changes on a device in real tim

问题:

Every time I change a code even it's only one line I have to run the command

sudo ionic cordova prepare ios 

and I have to click play button on Xcode to unable to upload the app on the iPhone and see the changes in action.

Basically every time I want to test the app, I am repeating this steps and each time it takes approximately 4 minutes to see if this single line of code I wrote is working or not. Is there a way to see this changes in real time?

If I run

sudo ionic serve

and if I make a change the changes are appear on the browser real time but I need to test the camera and the return key on the iPhone so browser doesn't work for me. For instance I can switch between the inputs with the "tab key" but I cannot switch between the inputs with the "return key".

Is there a way to see the changes in real time? That would save me a lot of time.

Yes, there is! The answer is Ionic DevApp

The Ionic DevApp is a free app that makes it easy to run your Ionic app directly on your iOS or Android device.

Skip dealing with frustrating Native SDK installation issues, just run ionic serve -c, open the DevApp, connect to the same network, and the app will automatically load and run your app.

The DevApp comes with many native plugins built right in, so you don’t need to worry about installing plugins.
