ios - 带条件的 Swift 过滤器

Question

我正在创建一个过滤器来过滤车辆数组。我根据价格、性能以及可选的传动装置类型进行过滤。

func filterCarSpecifications(among carSpecifications: [CarSpecification]) -> [CarSpecification] {

    let filteredCars = carSpecifications.filter {

        let performance = $0.car.ps ?? 0.0

        return $0.pricing.price >= IoC.filterDataService.selectedMinPrice.rounded(.down)
            && $0.pricing.price <= IoC.filterDataService.selectedMaxPrice.rounded(.up)
            && performance >= IoC.filterDataService.selectedMinPerformance
            && performance <= IoC.filterDataService.selectedMaxPerformance
    }

    if IoC.filterDataService.autoTransmision {
        return filteredCars.filter {
            let transmission: GearingType = .automatic
            return $0.car.gearingType == transmission
        }
    }

    return filteredCars
}

IoC.filterDataService.autoTransmision 是一个 bool 值，用于检查用户是否只想查看自动车辆。有没有办法将这个额外值包含到我的原始过滤器中？

附加

&& IoC.filterDataService.autoTransmision ? $0.car.gearingType == .automatic : true

你的初始条件
