Fix SwiftLint

The change in this branch makes it possible for SwiftLint to generate warnings again. This is achieved by modifying a build setting parameter with XcodeGen.

Known issue

Because of this fix, a new warning appears in Xcode:

This needs to be fixed in XcodeGen, but there is a way to fix it manually. Drag the Headers build phase before the SwiftLint build phase under Core target's build settings. This fix remains in effect until a new make sync command is executed.

An issue has been opened in XcodeGen's repository about the warning:
yonaskolb/XcodeGen#1507

[vargaat]

We will deal with this new warning in the PR that removes ObjC bridging headers.
