Code migration from Swift 2.x to Swift 4
We have big enough project which is built up with Swift 2.x and now Apple has just released Swift 4 so to move forward for latest version of Swift which path we can choose...
Do we need to migrate our code to Swift 3 first? Or we can directly migrate our code to Swift 4 using Xcode 9?
Yes, you must migrate your code in Swift 3 compatible version. Xcode 9 allows conversion/migration from swift 3.0 only.
Swift 3.2 is supported by Xcode 9 & Xcode 8 both.
Convert your source code from Swift 2.0 to 3.2 using Xcode 8 and then continue with Xcode 9 (Swift 3.2 or 4).
For easier migration of your code, follow these steps: (it will help you to covert into latest version of swift supported by your Xcode Tool)
