在Swift中隐藏(跳过) print()和debugPrint()的方法

#if DEBUG
func print(_ items: Any..., separator: String = " ", terminator: String = "\n") {
    // 调试模式下，保留print()方法的实现
    Swift.print(items, separator: separator, terminator: terminator)
}

func debugPrint(_ items: Any..., separator: String = " ", terminator: String = "\n") {
    // 调试模式下，保留debugPrint()方法的实现
    Swift.debugPrint(items, separator: separator, terminator: terminator)
}
#else
func print(_ items: Any..., separator: String = " ", terminator: String = "\n") {
    // 发布模式下，隐藏print()方法的实现
}

func debugPrint(_ items: Any..., separator: String = " ", terminator: String = "\n") {
    // 发布模式下，隐藏debugPrint()方法的实现
}
#endif
