在xcode中使用%运算符

let a = 10
let b = 3
let result = a % b
print(result) // 输出结果为1

let number = 7
if number % 2 == 0 {
    print("偶数")
} else {
    print("奇数")
}

for i in 1...10 {
    if i % 2 == 0 {
        print("\(i) 是偶数")
    } else {
        print("\(i) 是奇数")
    }
}

let totalSeconds = 3665
let hours = totalSeconds / 3600
let minutes = (totalSeconds % 3600) / 60
let seconds = (totalSeconds % 3600) % 60
print("\(hours)小时 \(minutes)分钟 \(seconds)秒")
