XCTAssertEqual.swift

let dictionary: [String: Any] = [
    "color": "blue",
    "width": 5.0,
]

func XCTAssertEqual(_ l: [String: Any], _ r: [String: Any]) {
    l.keys.forEach { key in
        if let left = l[key] as? String, let right = r[key] as? String {
            XCTAssertEqual(left, right)
        } else if let left = l[key] as? CGFloat, let right = r[key] as? CGFloat {
            XCTAssertEqual(left, right)
        } else if let left = l[key] as? Bool, let right = r[key] as? Bool {
            XCTAssertEqual(left, right)
        } else {
            XCTFail()
        }
        // And on and on with all your supported types...
    }
}

XCTAssertEqual(dictionary, dictionary)

(was playing in a Playground on iPad, no XCTest there)

@akosma That looks very good but doesn't work with nested arrays unfortunately.

try this

func XCTAssertEqual(_ l: [String: Any], _ r: [String: Any]){
    XCTAssertEqual(NSDictionary(dictionary: l), NSDictionary(dictionary: r))
}

@AndreiVidrasco That should work but unfortunately it doesn't support nested objects, like I wrote before with AnyHashable.
