swift:如何删除特定字符？

Question

之类的字符串! !!耶! ! ，我想删除 ! 和 ，当我这样编码时

for index in InputName.characters.indices {
    if String(InputName[index]) == "" || InputName.substringToIndex(index) == "!" {
        InputName.removeAtIndex(index)
    }
}

出现“fatal error: subscript: subRange extends past String end”错误，我该怎么办？谢谢:D
