我尝试迭代多个数组，然后将所有内容放入另一个数组中。 这是我要上课的课程：
class Place {
var names = [String]()
var messages = [String]()
var latidudes = [Double]()
var longitudes = [Double]()
var locations = [CLLocationCoordinate2D]()
}
这是我的职责：
private func placesArrayLoop() {
let CoffeeShopNames = ["aCoffee","bCoffee", "cCoffee"]
let messages = ["message0", "message1", "message2"]
let latitudes = [40.232320, 40.232321, 40.232322]
let longitudes = [-95.388069, -95.388068, 95.388067]
for (name, message, latitude, longitude) in zip(CoffeeShopNames, messages, latitudes, longitudes) {
let place = Place()
place.names.append(name)
place.messages.append(message)
place.latitudes.append(latitude)
place.longitudes.append(longitude)
}
}
它给了我错误，＆＃34;呼叫中的额外参数指向zip数组行中的纬度。我假设它是swift 3的新语法错误，但我已经环顾四周，无法找到解决方法。但是下面的代码很有用......
let strArr1 = ["Some1", "Some2", "Some3"]
let strArr2 = ["Somethingelse1", "Somethingelse2", "Somethingelse3"]
for (e1, e2) in zip(strArr1, strArr2) {
print("\(e1) - \(e2)")
}
所以现在我真的很困惑。
