I am learning Swift (but am a 30yr C programmer) to build an Ipad app for company internal use. It will be on about 30 Ipads. I have read that all Ipad apps must be in the Apple store and go through an extensive approval process by Apple? How do we build apps for internal or personal use. What if we don't want our app publically available? In my case public access is OK but the app is useless without the custom hardware it will control via TCP/IP. Will that fact disqualify the app by Apple? There must be a way to do this? I know Adroid can. What is Apples procedure for this? If there is a reasonable fee, that's fine.

Seasoned C developer with i86 and embedded hardware but new to ios. I built a screen with two buttons in Swift. But where is the source code? I see source listings that look like frameworks but nothing that contains my two buttons. My next step is to assign a TCP/IP data string to each button. What library would be recommended for that? TIA
