Swift语句是否可以跨多行拆分？

报告说：

Swift不要求您在代码中的每条语句后都写分号（；），尽管您可以根据需要这样做。但是，如果要在一行上编写多个单独的语句，则需要分号

---

这意味着Swift使用换行符作为语句终止符。是否每个语句都需要放在一行中？或者可以在单个语句中插入换行符吗？如果可以，确定换行符是否终止语句的规则是什么？

Swift可以在语句中插入换行符。这在类似以下的复杂命令中非常常见：

 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)

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

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

但是你可以把简单的语句分解成这样：

 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)

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

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

通常，您可以在操作数或标点之间拆分行

可以使用换行符进行多行注释，如下所示：

 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)

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

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