    Parameters

    populator

    A block or function that populates the new message, which is passed into the block as an inout argument.

    Returns

    The message after execution of the block.

    This method acts essentially as a “builder” in that the initialization of the message is captured within the block, allowing the returned value to be set in an immutable variable. For example,

    let msg = MyMessage.with { $0.myField = "foo" }
msg.myOtherField = 5  // error: msg is immutable
