Question

尝试将一些简单的数字加在一起。在最后一行得到“表达式太复杂，无法在合理的时间内解决......”错误。为什么？当然不能简单得多吗？

    let year   = calendar.component(.CalendarUnitYear, fromDate: inputGregorianDate)
    let month  = calendar.component(.CalendarUnitMonth, fromDate: inputGregorianDate)  
    let day    = calendar.component(.CalendarUnitDay, fromDate: inputGregorianDate)

    // Conversion Calulation
    let AGR = year/100
    let BGR = AGR/4
    let CGR = 2 - AGR + BGR
    var EGR = 0.00
    if (month <= 2 ) {
        EGR = 365.25 * Double(year + 4716)
    } else {
        EGR = 365.25 * Double(year + 4716);
    }
    let FGR = 30.6001 * Double(month + 1);
    let dateJulian = Double(CGR + day + EGR + FGR - 1524.5)

Answer 1

// Conversion Calulation
let AGR = Double(year) / 100
let BGR = AGR / 4.0
let CGR = 2.0 - AGR + BGR
var EGR = 0.0

// this conditional doesn't make any sense
if (month <= 2 ) {
    EGR = 365.25 * Double(year + 4716)
} else {
    EGR = 365.25 * Double(year + 4716)
}

let FGR = 30.6001 * Double(month + 1)
let dateJulian = CGR + Double(day) + EGR + FGR - 1524.5

基本添加 - 表达式太复杂错误（Swift）
