Fix Swift Language mode for UITest targets (#20)

# Fix Swift Language mode for UITest targets

## ♻️ Current situation & Problem
Even though #19 enabled Swift 6 Language Mode on the project wide build
settings for the UITest project, all the individual targets had a manual
override specifying Swift 5. This was fixed by this PR making sure Swift
6 is enabled by default for all targets.

## ⚙️ Release Notes 
* Fixed Swift 6 Language Mode for UITest targets.
