Does it make sense to start learning Objective C from scratch if the programmer has an old model iphone?

Question

Objective-C

In my case, this is iphone 5. I'm afraid that I won't be able to fully test the functionality of the developed program, I don't have the latest model at my disposal. Or, for example, embed a function that is in the latest models. In my case - 3D touch.

You're asking about unrelated things...
Language is a tool for development, it needs to be learned.
