我正在尝试连接到我的Xcode Server的内部socket.io。我用这个初始化客户端：
self.socket.connect()但是当我使用2016-07-15 16:13:49.179 MyApp[84260:1941316] LOG SocketIOClient: Adding handler for event: connect

"Got unknown error from server Welcome to socket.io."
)
时，我得到了这个回复：
socket.io.js我尝试更改xcode/internal/socket.io/1/文件或Welcome to socket.io的路径，但它们都给出了相同的响应，而{{1}}被替换为该文件的内容。< / p>

尝试将#' subsets to list
aSubset <- lapply(1:5, FUN = function(X){
eval(parse(text = sprintf("subset(data, AD%d == 1)", X)))
})
#' assuming your original data came from a data.frame,
colNames <- c('u','v','w','x','z')
#' for each list element, calculate column means. I suggest modifying
#' the output to the structure you want, i.e. by using llply or etc
require(plyr)
adMeans <- ldply(aSubset, function(x){
colMeans(x[, colNames])
})
#' for a clearer output, these might be useful:
colnames(adMeans) <- colNames
rownames(adMeans) <- sprintf('AD%d', 1:5)
作为协议，如下所示：

在服务器端和客户端检查socket.io版本，两者不匹配可能是导致此错误的原因

我已将 swift 客户端框架更新到最新的 16.0.1 版本。但是这个错误发生了。还有一个未解决的问题：https://github.com/socketio/socket.io-client-swift/issues/1355
我通过恢复到旧的稳定版本来解决这个问题：
pod 'Socket.IO-Client-Swift', '~> 15.2.0'
