代码：
var error: NSError?
if (xmppStream!.authenticateWithPassword(password, error: &error) ) {
print("authentification successful")
}出错：
SwiftXMPP/AppDelegate.swift:140:25: Cannot invoke ‘authenticateWithPassword’ with an argument list of type ‘(String, error: inout NSError?)’
Expected an argument list of type ‘(String!)’
如图：
搜：
swift Cannot invoke ‘authenticateWithPassword’ with an argument list of type ‘(String, error: inout NSError?)’
找到原型是：
- (BOOL)authenticateWithPassword:(NSString *)inPassword error:(NSError **)errPtr
{所以去改为：
do{
if try xmppStream!.authenticateWithPassword(self.password) {
print("authentification successful")
}
}catch{
print("error")
}即可。
