Question

因此，在诊断出我的代码后，我将其缩小到一行，这导致我的整个项目需要几秒钟到几小时才能构建。我将参数传递给Alamofire以发送到我的API，但它们会导致Xcode永远索引/构建。谁能找出原因？

有问题的行

        var credit_union : String = ""
        var activity : String = ""
        var task : String = ""
        var billing_options : String = ""

        var sun : Float = 0
        var mon : Float = 0
        var tue : Float = 0
        var wed : Float = 0
        var thu : Float = 0
        var fri : Float = 0
        var sat : Float = 0
        var total : Float = 0

        var sun_notes : String = ""
        var mon_notes : String = ""
        var tue_notes : String = ""
        var wed_notes : String = ""
        var thu_notes : String = ""
        var fri_notes : String = ""
        var sat_notes : String = ""

        let approval : String = ""
        let department : String = currentUser.department
        let submitted : String = "Not Submitted"
        let date_of_time : Date = startDatePassing + 1.day
        let id : Int = 0


let parameters: Parameters = [
            "credit_union": credit_union,
            "activity": activity,
            "task" : task,
            "billing_options" : billing_options,
            "sun" : sun,
            "mon" : mon,
            "tue" : tue,
            "wed" : wed,
            "thu" : thu,
            "fri" : fri,
            "sat" : sat,
            "total" : total,
            "sun_notes" : sun_notes,
            "mon_notes" : mon_notes,
            "tue_notes" : tue_notes,
            "wed_notes" : wed_notes,
            "thu_notes" : thu_notes,
            "fri_notes" : fri_notes,
            "sat_notes" : sat_notes,
            "approval" : approval,
            "department" : department,
            "submitted" : submitted,
            "date_of_time" : date_of_time
        ]

Answer 1

构建需要很长时间，因为有一个大字典文字。您可以尝试使用dict[key] = value语法创建字典。

let parameters: Parameters = {
    var dict = Parameters()
    dict["credit_union"] = credit_union
    dict["activity"] = activity
    // the rest of the KVPs goes here
    return dict
}()

Answer 2

我通常通过一次构建一个问题来解决这类问题（我也看到它发生在复杂的字符串，长数组等）。 e.g。

var parameters: Parameters = ["credit_union": credit_union]
parameters["activity"] = activity
// etc.

Swift 3和Alamofire：非常慢的构建时间
