URL的Swift 3语法问题

Question

我试图在Xcode 8中将C#示例转换为swift,但我一直遇到语法问题.查看代码的小例子:

public class ToonAPIClient {
    private var APIManagerBaseAddress: URL!
    private var APIBaseAddress: URL!

    public init() {
        APIManagerBaseAddress = URL(String: "https://path.to.baseurl/")
        APIBaseAddress = URL(String: APIManagerBaseAddress + "append/path/data/")
    }
}

APIManagerBaseAddress我收到错误

参数标签'(String :)'与任何可用的重载都不匹配

并为APIManagerBaseAddress

二进制运算符'+'不能应用于'URL'类型的操作数 和'字符串'

任何帮助都很受欢迎,因为我尝试了一些语法可能性:)

-edit-感谢大家的帮助和建议!

首先,它是init(string:)不是init(String:)也用appendingPathComponent用APIManagerBaseAddress.

APIManagerBaseAddress = URL(string: "https://path.to.baseurl/")!

// you can add values like that in Swift
APIBaseAddress = APIManagerBaseAddress.appendingPathComponent("append/path/data/")
