Summary:
Even though the "Convert to Modern Objective-C" feature works almost perfectly, a very common syntax of dictionary creation fails to fully convert to the "Modern Objective-C". The syntax is NSDictionary's +dictionaryWithObjects:forKeys (and -dictionaryWithObjects:forKeys init method).

Steps to Reproduce:
Create a project and add this simple code (to be converted):

    NSDictionary *dict = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:@"1", @"2", nil] forKeys:[NSArray arrayWithObjects:@"A", @"B", nil]];

Expected Results:
    NSDictionary *dict = @{ @"A" : @"1", @"B" : @"2" };

Actual Results:
    NSDictionary *dict = [NSDictionary dictionaryWithObjects:@[@"1", @"2"]  forKeys:@[@"A", @"B"]];

This is quite clearly a partial convert.

Regression:
N/A.

Notes:
While this is not even critical, it confuses people and actually misses the convert of one of the ugliest constructions with the old syntax which is the arrayWithObjects:forKeys:.
