Using trailing closure syntax for the last parameter in a call is often the most elegant way to handle it. But if the call requires multiple
function-type arguments, the use of a trailing closure can be messy and confusing. In such cases, it’s better to pass closure expressions as normal
arguments.
Noncompliant code example
var x = complexOperation(
arg: 2,
op1: {$0 + 10}
) {$0 * $0}
Compliant solution
var x = complexOperation(
arg: 2,
op1: {$0 + 10},
op2: {$0 * $0}
)
