Get the NSDate representations of the first and last days of the given month in the specified year

[Date]MonthFirstLastDays.m

// Return an array:
// Index 0: NSDate for the First day of the month
// Index 1: NSDate for the Last day of the month
+ (NSArray *)dateRangeForYear:(NSInteger)year Month:(NSInteger)month{
    
    // Build calendar and date components
    NSCalendar* calendar = [NSCalendar currentCalendar];
    NSDateComponents* dateComps = [[NSDateComponents alloc] init];
    
    // Set the month
    [dateComps setMonth:month];
    
    // Get the range
    NSRange range = [calendar rangeOfUnit:NSDayCalendarUnit
                              inUnit:NSMonthCalendarUnit
                             forDate:[calendar dateFromComponents:dateComps]];
    
    NSDate *fromDate = [NSDate dateWithYear:year month:month day:1];
    NSDate *toDate  = [NSDate dateWithYear:year month:month day:range.length];
    
    return @[fromDate, toDate];
}

Could be wrong but i don't think [NSDate dateWithYear:year month:month day:1] is valid
