Generated mock adds `@escaping` to init when dictionary has a function value

[jwsinner]

Basic reproducer:

/// @mockable
protocol Tester {
  var testDictionary: [String: () -> String] { get }
}

Produces:

class TesterMock: Tester {
    init() { }
    init(testDictionary: @escaping [String: () -> String]) {
        self._testDictionary = testDictionary
    }

    private var _testDictionary: ([String: () -> String])! 
    var testDictionary: [String: () -> String] {
        get { return _testDictionary }
        set { _testDictionary = newValue }
    }
}

The @escaping in the init causes a compiler error due to it be associated with a dictionary rather than a function.

Thanks for reporting this issue. The problem comes from mockolo handling types as raw strings instead of structured data, which leads to ad-hoc type operations. In this case, the type string has an arrow (->), so the dictionary is treated as a closure.

I'm working on updating SwiftType to use a structured format, which should fix this and other related issues.
