当我尝试运行程序时会弹出错误但如果我注释掉对Utility.subscribeToServer函数的调用它会正常工作。
let targetURL = "\(BASE_URL)/users/\(self.userId)/subscribe"
Utility.subscribeToServer(targetURL, deviceId, self.deviceType, completion: {(data, response, error) -> Void in
print(data)
})
Utility.subscribeToServer功能
class func subscribeToServer(targetURL : NSURL!, deviceId : NSData, deviceType : String, completion : (data : NSData?, response : NSHTTPURLResponse, error : NSError?) -> Void) {
print("Performing POST request")
let request = NSMutableURLRequest(URL: targetURL)
request.HTTPMethod = "POST"
let postBody = "deviceId=\(deviceId)&deviceType=\(deviceType)"
request.HTTPBody = postBody.dataUsingEncoding(NSUTF8StringEncoding)
let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
data, response, error in
dispatch_async(dispatch_get_main_queue(), {() -> Void in
completion(data: data, response: response as! NSHTTPURLResponse, error: error)
})
}
task.resume()
}
完成错误：

1. While emitting SIL for 'subscribeToServer' at /Users/dk/Desktop/IosApps/OT/OT/ViewController.swift:75:5
我无法弄清楚问题所在。我的xcode也有“源编辑器功能有限”错误，该错误与上述错误同时发生。
我真的很感激一些帮助。
