Problem of version 4.1

[SafaaB4E]

I got this errors even i changed swift version to 4.1.

I started using the SearchTextField 1.2.1 and it worked fine til run pod update.

The podFile:
pod 'SearchTextField', '~> 1.2.1'

Now cocoaPods only installs the 1.2.2 version which is not compatible anymore with swift 4.1 version.
