Why do I keep having to "trusting" my developer to test my app every time i make a new improvement?

Can anyone tell me if I can do something like “always trust this developer”, or something on my device, to test my own apps? The thing is, the simulator is VERY slow and the best way really is just to test my stuff on an actual device, [I’m using an iPad Air by the way], but everytime I make a change to my app, I have to connect my device to the internet [which isn’t really accessible at my leisure], and then re “trust” my developer account, and believe me, that gets to be REALLY OLD FAST. Especially when. get to the last project in this book, I’m currently at the very end of the second, I will have to keep testing it on an actual device. Any ideas??

Side Note: I posted a question about converting file formats to [.scn] in Xcode, and it seems no one knows the answer?!?!:frowning:

Is this what you’re talking about?

I am new to all this, the other thing I dealt with was creating and downloading the cert file for my device.
