Good enough for Xcode?

Hi everyone, I have an old 2010 macbook pro that I would like to upgrade because its gotten very slow. I use it to make websites, for xcode/android studio and the usual procrastination, stopped using illustrator and such programs because it takes forever. This new macbook looks very appealing, I was considering the retina macbook pro as well but carrying my current macbook in my backpack around town is.. not comfortable, however the thing that concers me is if its good enough for debugging and if I need to buy a new USB C cable for my iphone. I'd like to know what other fellow developers think about the new Macbook
