Компиляция Swift проблемы исходных файлов с созданием словаря

Question

Я создаю словарь в быстром и она принимает очень много времени (20 мин), чтобы скомпилировать

import Foundation 

extension Renter { 
    var dictionaryRepresentation: [String: Any]? { 
     guard let email = email, 
      let zipCode = wantedZipCode, 
      let city = wantedCity, 
      let state = wantedState, 
      let country = wantedCountry, 
      let creditRating = creditRating, 
      let firstName = firstName, 
      let lastName = lastName, 
      let id = id 
      else { return nil } 

     var dictionaryRepresentation: [String: Any] = [UserController.kEmail: email, 
       UserController.kZipCode: zipCode, 
       UserController.kCity: city, 
       UserController.kState: state, 
       UserController.kCountry: country, 
       UserController.kCreditRating: creditRating, 
       UserController.kPetsAllowed: wantsPetFriendly, 
       UserController.kSmokingAllowed: wantsSmoking, 
       UserController.kWasherDryer: wantsWasherDryer, 
       UserController.kGarage: wantsGarage, 
       UserController.kDishwasher: wantsDishwasher, 
       UserController.kBackyard: wantsBackyard, 
       UserController.kPool: wantsPool, 
       UserController.kGym: wantsGym, 
       UserController.kFirstName: firstName, 
       UserController.kLastName: lastName, 
       UserController.kMonthlyPayment: Int(wantedPayment), 
       UserController.kID: id, 
       UserController.kBedroomCount: Int(wantedBedroomCount), 
       UserController.kBathroomCount: wantedBathroomCount, 
       UserController.kBio: bio ?? "No bio available", 
       UserController.kStarRating: starRating, 
       UserController.kMaritalStatus: maritalStatus ?? "Not specified", 
       UserController.kCurrentOccupation: currentOccupation ?? "No occupation yet", 
       UserController.kWithinRangeMiles: withinRangeMiles, 
       UserController.kBankruptcies: bankruptcies, 
       UserController.kCriminalHistory: criminalHistory ?? "", 
       UserController.kDriversLicenseNumber: driversLicenceNum ?? "", 
       UserController.kDriversLicensePicURL: driversLicensePicURL ?? "", 
       UserController.kEvictionHistory: evictionHistory ?? "", 
       UserController.kIncome: income ?? 0, 
       UserController.kIsStudent: isStudent ?? false, 
       UserController.kIsVerified: isVerified ?? false, 
       UserController.kPreviousAddress: previousAddress ?? "", 
       UserController.kReasonsForLeaving: reasonForLeaving ?? "", 
       UserController.kSchool: school ?? "", 
       UserController.kStudentID: studentID ?? "", 
       UserController.kStudentPhotoIdURL: studentPhotoIDURL ?? ""] 

     guard let profileImageArray = self.profileImages?.array as? [ProfileImage] else { return dictionaryRepresentation } 

     let imageURLs = profileImageArray.flatMap({$0.imageURL}) 

     dictionaryRepresentation[UserController.kImageURLS] = imageURLs 

     guard let occupationHistory = self.occupation?.allObjects as? [Occupation] else { return dictionaryRepresentation } 

     let occupationDicts = occupationHistory.flatMap({ $0.dictionaryRepresentation }) 

     dictionaryRepresentation[UserController.kOccupationHistory] = occupationDicts 

     return dictionaryRepresentation 
    } 

} 

Я проверил это, и я знаю, что это создание этого словаря, потому что я попытался удалить половину словаря, и он компилируется намного быстрее. Есть ли у кого-нибудь советы о том, как ускорить это?

Answer 1

Назначение буквального значения для словаря является ошибкой в ​​текущих версиях Swift и может вызвать проблемы с компиляцией. Быстрое обходное решение - избегать литералов и делать это долгий путь.

var dictionaryRepresentation = [String: Any]() 
    dictionaryRepresentation[key1] = value1 
    dictionaryRepresentation[key2] = value2 
    ... 

Он генерирует больше кода, но компилируется очень быстро.

Дает полный пример кода, который компилирует очень быстро таким образом ... Я уверен, что вы можете изменить свой собственный код, так же ...
