Issue Description

Errors from methods changing.

What

After updating to version 4.0.1, I'm still getting these errors:

'cropped(to:)' has been renamed to 'cropping(to:)'
'applyingFilter(_:parameters:)' has been renamed to 'applyingFilter(_:withInputParameters:)'

Reproduce

The pod cannot be built with Xcode 9 GM Seed.

Kingfisher 4 is for Swift 4. If you are using Swift 3.2, please roll back to Kingfisher 3.

Sorry, I am using Swift 4

Please check:

1. The Swift Version setting of Kingfisher is set to Swift 4.
2. If you have a .swift-version file under your project, make sure the content of it is "4.0".
3. Try to clean your project.

If the problem is still there, I suggest to submit it to CocoaPods, since there should be no problem in Kingfisher for it. We have already been using it in our Swift 4 project for a while.

Thanks I fixed it by changing the language to Swift 4 for Kingfisher.

Version 4.1.0 should fixed this kind of problems (mismatching versions with Kingfisher code and build setting when used with CocoaPods)
