Is Xcode 6.3 with Swift 1.0 possible?

Question

Is it possible to use Xcode 6.3 but stay with Swift 1.0?
Using the iOS 8.2 SDK does not help, and I could not find any switch for the Swift version ...

EDIT: I have an extension build in Swift 1.0 which I do not want to touch, but update my main project

Why would you need to go back to Swift 1.0? – Mou

I don't want to go back - I want to stay – Psychokinesis

Stay with the old Xcode, dont update to Xcode 6.3 – Breadboard

@shmim: You do not have to target 8.3! I have a target of 7.0 for my main app and 8.2 for the Watch. – Psychokinesis

Answer 1

If you're having syntax problem then you can convert it to latest syntax. Also there is no way of using 1.0 in xcode 6.3

Thanks, but this will make the review process will Apple painful. I have a WatchKit App in Swift 1.0 and they are very cautious with updates before the Watch launch! – Psychokinesis

@Psychokinesis it's always better to adopt changes, you can't defer 1.2 for long. You have to use it at some point. Moreover you can't keep using xcode 6.2. I don't know how big is this for you but that's the interesting & challenging thing for you. – Orchardist

I absolutely agree - in general. Right now, there are some time constraints, unfortunately – Psychokinesis

Then I suggest you to use xcode 6.2, you can download dmg form here. – Orchardist

Answer 2

No, that is not possible. Xcode 6.3 comes with Swift 1.2. If you are concerned about compatibility, you can convert your swift 1.0 code into Swift 1.2 using Xcode 6.3

@styler1972: "not guaranteed" is a very positive term for the actual experience :) – Psychokinesis
