is there any limit for running apps on my own device instead of running in simulator ?

I don't think any of us understand what you're asking. You should be able to run apps on your device. In fact, it's better to test apps on a real device rather than the simulator.

i'm not sure if this is the same problem, or if this is what you meant, but when i'm developing an app in Adobe Flash CC 2015 (using Air for iOS), my device won't show up in the device section, so i can't install the app on any of my devices. i was able to before, but not now. i thought maybe it was just my ipad Pro, but it won't show my mini, or iphone 6s either, both of which i was able to install my apps before...

Any reason why this is?

*update - i gues the way around this is to just go ahead and create the .ipa file, import into itunes and then sync to device - app works great on all devices. it's a few extra steps, but its still quick and easy.
