iOS: Migration (Upgrade) from Swift 3 to Swift 4

Recent major update in iOS application development tool Xcode 9 supports Swift 3.2 & 4 programming language.

I've my app developed with Swift 3 version and I want to convert/migrate, complete source code from Swift 3 to Swift 4. During migration, it's showing me 354 errors.

These errors are fixable. The solution of error is suggested by Xcode itself. But there are 354 errors. How can I fix them all at once? Manual fixing of each error one-by-one will be a time-consuming activity.

Is there any feasible solution to fix all errors at once.

Here is a snapshot with the sample.

We have a better option to fix this error at once. It can be solved out from Editor menu

Use this option to fix all the error at once in class.

Note: You cannot always rely on Xcode suggestions, but for migration case it will work in most of the case.
