How to create folder in NSLibraryDirectory in mac - ios

Question

Im trying to create an folder in user library directory,but its not creating. Is there any mistake in the below code.
databaseName = #"KITSMAW0051_DB.sqlite";
// Get the path to the documents directory and append the databaseName
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [documentPaths objectAtIndex:0];
NSString *folder = #"Swasstik";
databasePath = [[documentsDir stringByAppendingPathComponent:folder ] stringByAppendingPathComponent:databaseName];

Answer 1

Ok first of all databasePath describes a path to a file not a directory. But let's say you actually want to create "Swasstik" folder inside user's Library:
// Your code
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [documentPaths objectAtIndex:0];
NSString *folder = #"Swasstik";
// I edited here to keep only the folder
NSString *folderPath = [documentsDir stringByAppendingPathComponent:folder];
// At this point we got the path to the folder
// but we want to actually go on and create it
// NSFileManager to the rescue!
NSFileManager *manager = [NSFileManager defaultManager];
[manager createDirectoryAtPath: folderPath
withIntermediateDirectories: NO
attributes: nil
error: nil];
Of course you can study and set the manager as you like and also implement some error handling. I hope that this makes sense...

databaseName = #"KITSMAW0051_DB.sqlite";
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [documentPaths objectAtIndex:0];
NSString *folder = [documentsDir stringByAppendingPathComponent:#"Swasstik"];
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error = nil;
if (![fileManager fileExistsAtPath:folder]) {
[fileManager createDirectoryAtPath:folder withIntermediateDirectories:YES attributes:nil error:&error];
}
if (error != nil) {
NSLog(#"Some error: %#", error);
return;
}
NSString *databasePath = [folder stringByAppendingPathComponent:databaseName];
