CatchLoop

The function can be used to iterate over a sequence (implementing Sequence-protocol).

It returns a dictionary containing either the returned value or a thrown error.

CatchLoop.swift

func catchloop<I : Hashable, S: Sequence where S.Iterator.Element == I>
    (_ range: S, _ f: (I) throws -> Any) -> [I:Any] {
    var dict = [I:Any]()
    for i in range {
        do {
            let e = try f(i)
            dict[i] = e
        } catch let e { dict[i] = e }
    }
    return dict
}
