how to find size of my iphone app programatically?

3 Solutions Collect From Internet About “how to find size of my iphone app programatically?”

NSString *folderPath = [[NSBundle mainBundle] bundlePath];
NSArray *filesArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:folderPath error:nil];
NSEnumerator *filesEnumerator = [filesArray objectEnumerator];
NSString *fileName;
unsigned long long int fileSize = 0;

while (fileName = [filesEnumerator nextObject]) {
    NSDictionary *fileDictionary = [[NSFileManager defaultManager] fileAttributesAtPath:[folderPath stringByAppendingPathComponent:fileName] traverseLink:YES];
    fileSize += [fileDictionary fileSize];
}

NSLog(@"App size : %lld",fileSize);

If anyone is still looking for answer then: please note fileAttributesAtPath method is depriciated so use attributesOfItemAtPath method

Example:

//get full pathname of bundle directory
NSString *bundlePath = [[NSBundle mainBundle] bundlePath];

//get paths of all of the contained subdirectories
NSArray *bundleArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:bundlePath error:nil];

//to access each object in array
NSEnumerator *filesEnumerator = [bundleArray objectEnumerator];

NSString *fileName;

unsigned long long int fileSize = 0;
NSError *error = nil;

//return next object from enumerator
while (fileName = [filesEnumerator nextObject])
{
    NSDictionary *fileDictionary = [[NSFileManager defaultManager] attributesOfItemAtPath:[bundlePath stringByAppendingPathComponent:fileName] error:&error];

    fileSize += [fileDictionary fileSize];
}
//converts a byte count value into a textual representation that is formatted with the appropriate byte modifier (KB, MB, GB and so on)
NSString *folderSizeStr = [NSByteCountFormatter stringFromByteCount:fileSize countStyle:NSByteCountFormatterCountStyleMemory];
NSLog(@"App size (bundle size): %@ \n\n\n",folderSizeStr);

Swift Answer –
SWIFT 3.x

let bundlePath = Bundle.main.bundlePath
let bundleArray  = FileManager.default.subpaths(atPath: bundlePath)
var fileSize : UInt64 = 0
for file in bundleArray! {
    do {
        let attr = try FileManager.default.attributesOfItem(atPath: bundlePath + "/" + file )
        let xfileSize = attr[FileAttributeKey.size] as? UInt64 ?? 0
        fileSize =  fileSize + xfileSize
    } catch {
    }
}
let folderSize = ByteCountFormatter.string(fromByteCount: Int64(fileSize), countStyle: .memory)
print("App size (bundle size): \(folderSize)")//xx MB

Which will gives you app size in bundle –
