localizedCaseInsensitiveCompare does not seem to work with swedish characters

Question

I\'m trying to sort an array alphabetically. In the swedish alphabet the letter Å is third last letter in the alphabet so the below array should be sorted like A, B, Å

Answer 1

Perhaps the current locale is not the Swedish locale?

It works as expected if you explicitly use a Swedish locale for sorting the strings:

NSArray *test = @[@"Å", @"A", @"B"];
NSLocale *swedish = [[NSLocale alloc] initWithLocaleIdentifier:@"sv"];

NSArray *sortedTest = [test sortedArrayWithOptions:0
                                   usingComparator:^(NSString  *v1, NSString *v2) {
    return [v1 compare:v2 options:NSCaseInsensitiveSearch
                 range:NSMakeRange(0, [v1 length])
                locale:swedish];
}];

// Output: A, B, Å
