IOS: migration (upgrade) from Swift 3 to Swift 4

Question

A recent major update to the iOS app development tool Xcode 9supports a programming language Swift 3.2 & 4.

I developed my application with Swift 3 version and I want to convert / migrate the full source code from Swift 3 to Swift 4. During the migration, he showed me 354 errors.

These errors are fixable. A solution to the error is proposed by Xcode itself. But there are 354 errors. How can I fix them all at once? Manually correcting each error one after another will be a laborious task.

Is there a possible solution to fix all errors at once.

Here is a shot with a sample.
