Nutshell - I'm trying to get a highscore out of a plist
Here's the code to read the data:
var myOutput: AnyObject? = NSUserDefaults.standardUserDefaults().objectForKey("highscore")
println(myOutput!)
This is successful and the result of the println is the correct data
if myOutput != nil{
highscore = myOutput! as Int
}
This gives me a "Swift dynamic cast failure". From everything I've read this should be working, so any tips would be great.
Thanks to user2864740 got me on the right track. Correct solution is:
if myOutput != nil{
highscore = myOutput!.integerValue
}

Prettier formats if statement without curley braces into one line.
This means that this :
function getErrorMessage(response) {
let errorMessage = null;
if (!response.originalError.response)
errorMessage = 'network error';
else
errorMessage = response.originalError.response.data.errorMessage;
return errorMessage;
}
becomes this :
function getErrorMessage(response) {
let errorMessage = null;
if (!response.originalError.response) errorMessage = 'network error';
else errorMessage = response.originalError.response.data.errorMessage;
return errorMessage;
}
which is FAR more unreadable.
Is there a way of disabling this?
As asked in a similar question, it turns out that the answer is that you can not and will not be able to.
As for the WFT that an average senses, well... Apparently, opinionated doesn't mean respected and well-considered in opinion of many. It means that it's implementing the author's opinion.
So, surprisingly, the unexpected thing isn't the lack of configurability but rather that there are any options to be set at all! Go figure... Someone should create a new package called EvenPrettier or FexiblyPrettier and fork in more options. If I only knew how, I'd do it.
I finally ended up using Beautify - HookyQR extension for vscode

I'm converting my Swift2.3 code to Swift3, and got an error at the line where I used advancedBy. XCode showing me a replacing code that using offsetBy, but I still don't understand.
func unhideEmaimage(_ imageFile: String) {
let dotLocation = imageFile.characters.index(of: ".")
self.emaImage.texture = SKTexture(imageNamed: imageFile)
if dotLocation != nil {
let filenameInitial = imageFile.startIndex
let filenameLast = dotLocation!.advancedBy(-1)
let filenamePart:String = imageFile[filenameInitial...filenameLast]
}
And, following is the code that XCode showing me how to fix the error. However, I still don't know how to modify.
let filenameLast = "String.CharacterView corresponding to your index".index(dotLocation!, offsetBy: -1)
Please let me know the way to fix this error. Thank you in advance.
You should Write this:
let filenameLast = imageFile.index(dotLocation!,offsetBy: -1)
Got myself into trouble today trying to create a stored procedure from ax.
Here is a simple example:
static void testProcedureCreation(Args _args)
{
MyParamsTable myParams;
SqlStatementExecutePermission perm;
str sqlStatement;
LogInProperty Lp = new LogInProperty();
OdbcConnection myConnection;
Statement myStatement;
ResultSet myResult;
str temp;
;
select myParams;
LP.setServer(myParams.Server);
LP.setDatabase(myParams.Database);
//Lp.setUsername("sa");
//Lp.setPassword("sa");
sqlStatement = #"create procedure testproc
as begin
print 'a'
end";
//sqlStatement = strFmt(sqlStatement, myStr);
info(sqlStatement);
perm = new SqlStatementExecutePermission(sqlStatement);
perm.assert();
try
{
myConnection = new OdbcConnection(LP);
}
catch
{
info("Check username/password.");
return;
}
myStatement = myConnection.createStatement();
myResult = myStatement.executeQuery(sqlStatement);
while (myResult.next())
{
temp = myResult.getString(1);
info(temp);
if (strScan(temp, 'Error', 1, strLen(temp)) > 0)
throw error(temp);
}
myStatement.close();
CodeAccessPermission::revertAssert();
}
To be honest, in my real example I am using BCP and some string concat with a lot of | ' and "".
Anyway, here is what I got:
For a couple of hours I kept changing and retrying a lot of things and, a good thought came into my mind.
"Let's try with a much easier example and check the results!"
OK, no luck, the results were the same, as you can see in the pic above.
But for no reason, I tried to :
exec testproc
in my ssms instance and to my surprise, it worked. My small procedure was there.
It would be so nice if someone could explain this behavior and maybe what should be the correct approach.
This Q/A should provide an answer.

I'm using pocketshpinx for speech recognition in a custom C++ application. I noticed that sometimes the hypothesis string returned by the ps_get_hyp() method is an empty string.
Question: Is this an expected behaviour? If so, is there a way to tell pocketsphinx to not give the empty string as a hypothesis?
Following is a snippet of the relevant portion of my code:
do { ReadAudioBuffer(); } while (!in_speech);
while (in_speech) { ReadAudioBuffer(); }
ps_end_utt(ps);
hyp = ps_get_hyp(ps, NULL);
The ReadAudioBuffer() method:
void SpeechRecognizer::ReadAudioBuffer()
{
if ((k = ad_read(ad, adbuf, 2048)) < 0)
{
UE_LOG(LogTemp, Warning, TEXT("Failed to read audio\n"));
return;
}
ps_process_raw(ps, adbuf, k, FALSE, FALSE);
in_speech = ps_get_in_speech(ps);
FPlatformProcess::Sleep(0.005);
}
Question: Is this an expected behaviour?
There is nothing wrong with it
If so, is there a way to tell pocketsphinx to not give the empty string as a hypothesis?
If you said nothing what should be returned then?
FPlatformProcess::Sleep(0.005);
Sleep is not really needed here
So my code below shows me how I am doing prepare for segue. I'm not sure whats going on but its giving me some weird error I've used this same way before and it works but it just won't work in this application.
Code
override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!)
{
if segue.identifier == "select"
{
println("helloworld")
var index = tableView.indexPathForCell(sender as UITableViewCell!)
var object = self.objects[index!.row] as HMAccessory // object is a NSmutableArray its crashing on this next line where im casting it
//var dest = segue!.destinationViewController? as CharacristicsViewController!
// dest.detailItem = object
}
}
can anybody see anything wrong with this?
This is the error I'm getting.
