False Colon Violation inside guard and ternary operator

[Lukasz2891]

In 0.33.x

guard let requestData = try? JSONSerialization.data(withJSONObject: dictionary, options: .prettyPrinted),
            let storeURL = sandbox ? Self.sandboxStoreURL : Self.productionStoreURL else {
                return ...
        }

produces false Colon Violation (colon) inside the ternary ?: operator.

Hello, @Lukasz2891. Could you please post the whole method and all variables included? I could not understand what kind of variables sandboxStoreURL and productionStoreURL are.
I tried to check like below but it does not compile (Xcode 10.2.1).

class TestClass {
    public static var sandboxStoreURL: String? = "sandboxStoreURL"
    public static var productionStoreURL: String? = "productionStoreURL"
    public static var sandbox = false
}

class TestSubclass: TestClass {
    func test() -> String {
        let dict = ["dictKey":"dictValue"]
        guard let requestData = try? JSONSerialization.data(withJSONObject: dict, options: .prettyPrinted),
            let storeURL = sandbox ? Self.sandboxStoreURL : Self.productionStoreURL else {
                return "empty"
        }
        return "\(requestData)\(storeURL)"
    }
}

The essence of this bug it Self keyword. I tried 0.34 version, replaced Self with self and bug has gone.

It’s a default extension to a protocol so big „Self” is needed as a not specified type.

Hello, @Lukasz2891.
Made a PR, did it fix your case?

[Lukasz2891]

protocol Test {
    static var aaa: Any? { get }
    static var bbb: Any? { get }
}

extension Test {
    func foo() {
        let cond = false
        _ = cond ? Self.aaa : Self.bbb
    }
}

still produces colon :( in 0.34.0
