Head your browsers to Apple’s Development Center. Apple has just released Xcode 4.6, with iOS 6.1 support (Release!).

So far it has proven to be sooooo much stable. The previous release was a nightmare, specially during summertime. (Those of you who run Xcode on macbooks understand me… the entire machine turns into an iron!).

However, i’ve been reading quite a lot of reports, from many different sources, pointing out that although 4.6 *freezes less*, it still has a couple of severe bugs, that will lower your productivity.

Did you just get this error while trying to run your app in Xcode?…

The fix is fairly simple. Simply launch iTunes, make sure the device is plugged in, and synchronize. The error should be gone by now.

Told you, it was a quick fix!

This task is quite straightforward. First, import the following headers:

[cc lang=”objc”]#import
#import [/cc]

Now what?. Simple… use this method:

[cc lang=”objc”]
-(void)printMemoryUsage
{
mach_port_t host_port;
mach_msg_type_number_t host_size;
vm_size_t pagesize;

host_port = mach_host_self();
host_size = sizeof(vm_statistics_data_t) / sizeof(integer_t);
host_page_size(host_port, &pagesize);

vm_statistics_data_t vm_stat;

if (host_statistics(host_port, HOST_VM_INFO, (host_info_t)&vm_stat, &host_size) != KERN_SUCCESS)
{
NSLog(@”Failed to fetch vm statistics”);
}

/* Stats in bytes */
natural_t mem_used = (vm_stat.active_count +
vm_stat.inactive_count +
vm_stat.wire_count) * pagesize;
natural_t mem_free = vm_stat.free_count * pagesize;
natural_t mem_total = mem_used + mem_free;

NSLog(@”used: %u free: %u total: %u”, mem_used, mem_free, mem_total);
}
[/cc]

From time to time, Apple’s Review Team, for whatever reason, allows Apps that clearly violate the AppStore guidelines.

This time, Gridlee managed to got in. It’s free, and it’s somewhere around 85 megabytes. You can expect it to be removed sooner rather than later… so my recommendation would be… go and get it!.

You can install any ROMs you might have already downloaded. Playing Choplifter on an iPad Retina isn’t hi-tech, but i’ve always said, old school games are the best. You don’t need complex 3d algorithms, shadows, or near-perfect water effects to have fun.

After all, it’s all about getting rid of the bad guys… right!?
