Swift语句可以被拆分为多行吗?

Swift语句中可以有换行符。这在像这样的复杂命令中很常见:

 var query = HouseholdInfoTable.table
        .select(HouseholdInfoTable.uuid.distinct, HouseholdInfoTable.table[*])
        .join(PersonInfoTable.table, on: PersonInfoTable.householdUuid == HouseholdInfoTable.uuid)
        .filter(HouseholdInfoTable.houseNumber == houseNumber)
        .order(HouseholdInfoTable.sortName)

但你可以将简单的语句分解,如下所示:

let a = 1
 + 2
let b = 1 +
2

通常,您可以在操作数或标点符号之间分割线条

你可以像这样用换行符做多行评论:

let bigComment = """
anythingYou want can go here
asdlkasdkljfad
askjf
"""
