当移动到cocoapod时，Swift Routing枚举崩溃(Swift Routing enum crashes when moved to a cocoapod)

我最近一直在将代码重构为基础cocoapod，以便在多个项目中使用。 其中一个类是Alamofire的一个相当陈规定型的路由枚举。 它一直工作正常，直到被移入cocoapod ......现在正在崩溃。 一个示例实现：

public enum Router: URLRequestConvertible { static var baseURLString = "http://myserver.com/api" case Endpoint1(String, String) case Endpoint2(String, String, Date, Date) case Endpoint3(String, String) public var URLRequest: NSMutableURLRequest { var path : String! { switch self { case .Endpoint1(let id, _): return "/endpoint1/" + id case .Endpoint2(let id, _, _, _): return "/booking/\(id)/thing" case .Endpoint3(_, _): return "/authenticate" } } var parameters: [String: AnyObject] { switch self { case .Endpoint2(_, _, let startDate, let endDate): let params = ["startDate": startDate, "endDate" : endDate] return params default: let params = [String: AnyObject]() return params } } var method : Alamofire.Method { switch self { case .Endpoint2: return .POST default: return .GET } } var body : [String : AnyObject]?{ switch self{ case .Endpoint3(let email, let password): return ["email" : "\(email)", "password" : "\(password)"] default: return nil } } var header : [String: String]?{ switch self { case .Endpoint1(_, let token): return ["x-access-token" : token] default: return nil } } let URL = NSURL(string: Router.baseURLString)?.URLByAppendingPathComponent(path) let request = NSURLRequest(URL: URL!) let encoding = Alamofire.ParameterEncoding.URL let mutable = (encoding.encode(request, parameters: parameters).0) mutable.HTTPMethod = method.rawValue if let bodyParams = body{ mutable.setValue("application/json", forHTTPHeaderField: "Content-Type") mutable.addJsonArrayToRequestBody(bodyParams) } if let headerParams = header{ for param in headerParams{ mutable.setValue(param.1, forHTTPHeaderField: param.0) } } return mutable } }

失败线是：

for param in headerParams{

但正如在开发cocoapod中那样，我无法将调试器附加到该点，错误也不会超过EXEC_BAD_INSTRUCTION，这对于帮助不大。 如何进一步调试导致错误的原因？

I have recently been refactoring code into a base cocoapod for use in multiple projects. One such class is a pretty stereotypical routing enum for Alamofire. It's been working fine up until being moved into the cocoapod... which is now crashing. An example implementation:

public enum Router: URLRequestConvertible { static var baseURLString = "http://myserver.com/api" case Endpoint1(String, String) case Endpoint2(String, String, Date, Date) case Endpoint3(String, String) public var URLRequest: NSMutableURLRequest { var path : String! { switch self { case .Endpoint1(let id, _): return "/endpoint1/" + id case .Endpoint2(let id, _, _, _): return "/booking/\(id)/thing" case .Endpoint3(_, _): return "/authenticate" } } var parameters: [String: AnyObject] { switch self { case .Endpoint2(_, _, let startDate, let endDate): let params = ["startDate": startDate, "endDate" : endDate] return params default: let params = [String: AnyObject]() return params } } var method : Alamofire.Method { switch self { case .Endpoint2: return .POST default: return .GET } } var body : [String : AnyObject]?{ switch self{ case .Endpoint3(let email, let password): return ["email" : "\(email)", "password" : "\(password)"] default: return nil } } var header : [String: String]?{ switch self { case .Endpoint1(_, let token): return ["x-access-token" : token] default: return nil } } let URL = NSURL(string: Router.baseURLString)?.URLByAppendingPathComponent(path) let request = NSURLRequest(URL: URL!) let encoding = Alamofire.ParameterEncoding.URL let mutable = (encoding.encode(request, parameters: parameters).0) mutable.HTTPMethod = method.rawValue if let bodyParams = body{ mutable.setValue("application/json", forHTTPHeaderField: "Content-Type") mutable.addJsonArrayToRequestBody(bodyParams) } if let headerParams = header{ for param in headerParams{ mutable.setValue(param.1, forHTTPHeaderField: param.0) } } return mutable } }

The failure line is:

for param in headerParams{

But as it is in a development cocoapod, I can't attach a debugger to that point, nor is the error more than EXEC_BAD_INSTRUCTION, which is less than helpful. How can I further debug what's causing the error?

最满意答案

这是使用开发cocoapod时xcode调试器中的错误，实际错误是：

let URL = NSURL（string：Router.baseURLString）?. URLByAppendingPathComponent（path）

调用此方法时尚未设置静态baseURLString，导致URL为nil。 我已经看到多次出现的调试器在现在共享的代码中指出了不正确的行，不知道如何修复。

This is a bug in the xcode debugger when using a development cocoapod, the actual error was:

let URL = NSURL(string: Router.baseURLString)?.URLByAppendingPathComponent(path)

The static baseURLString had not yet been set when this method was called, leading the URL to be nil. I have seen multiple occurrences of the debugger pointing out the incorrect line when in the now shared code, not sure how to fix.
