Swift 5.3 has introduced a new feature of multiple trailing closures (see SONARSWIFT-461) in part to address the issue discussed in RSPEC-2958. Once SONARSWIFT-474 is implemented the rule RSPEC-2969 will cover all the cases of RSPEC-2958, so this rule becomes a duplicate.
Add support for Swift 5.3 Multiple Trailing Closures
Update rule S2969 to take into account multiple trailing closures
Trailing closure syntax should not be used when multiple parameters are of function type
