embed a 2nd project/app into my first app

[thephotographer]

hi. i have a 2 apps i have made, both stand alone, performing their completely different functions. first app i made is a media app, 2nd i have is a comms app. i now would like to create a 3rd app, which when launching has a home screen with say 9 buttons. button 1 will launch the media app part, button 2 will launch the comms app part, and buttons 3-9 will run other functions from within this 3rd home app im building.

previously i did it with just the 2, the home and the media apps. i just started with my media app code, and started writing the home app code into the media app. my current thoughts are to somehow copy all of that and put it inside the comms app i have made, but arent sure of the best way to do it.

i have seen once before one xcode project embedded within another xcode project, but im not sure how to do it. im probably searching for the wrong things because i cannot find anything relevant on these forums or the internet.

ideally that would be good, if i could make a new app, my home app, and embed the media app project and the comms app projects within the home app. and somehow link them so when i push a button in the home app it launches the respective other apps.

hopefully someone understands what im trying to say.. any help would be much appreciated!

thanks.
