I am buying a new Macbook. Is a Macbook Air with 8gb RAM and an i5 Processor enough for development?
Can I develop apps on a Macbook Air 8gb RAM i5 Processor?
Processor should not be the proiblem.
But 8GB RAM is not enough with recent versions of XCode. Need at least 16.
What is your MacOS version ?
If you want to start and play, you may donwnload an older version of XCode that is compatible with your version of MacOS: But that will be a very temporary solution, as this will not let you publish on Appstore and you will miss critical evolutions of Swift… So, that's just to get your feet wet, waiting for a more capable Mac.

select XCode or Xcode 8 in search field and select what you want to try.
You can easily develop apps on just 8 GB of ram on the latest version of XCode. I have no issues at all. Saying that it's not enough is just not true.
