我是Swift的新手.docuentation说:对于占用多行的字符串使用三个双引号(""").每个引用行开头的缩进被删除,只要它与结束引号的缩进匹配.例如:
let quotation = """
Even though there's whitespace to the left,
the actual lines aren't indented.
Except for this line.
Double quotes (") can appear without being escaped.
I still have \(apples + oranges) pieces of fruit.
"""
但是,我复制了这个示例并粘贴在我的xcode playground中,它显示错误:
Playground execution failed: error: SwiftBasics.playground:9:19: error:
unterminated string literal
let quotation = """
我究竟做错了什么 ？
