iOS app, programmatically get build version

You can try using the infoDictionary

NSDictionary *infoDictionary = [[NSBundle mainBundle]infoDictionary];

NSString *version = infoDictionary[@"CFBundleShortVersionString"];
NSString *build = infoDictionary[(NSString*)kCFBundleVersionKey];
NSString *bundleName = infoDictionary[(NSString *)kCFBundleNameKey]; 

When using MFMailComposeViewController for a "Contact Us" button, I use this code to get a formatted HTML on the e-mail from the user. It gives me all the info that I need to start helping solving any issue:

struct utsname systemInfo;
uname(&systemInfo);

NSDateFormatter *formatter = [[NSDateFormatter alloc]  init];
NSDate  *date = [NSDate date];
[formatter setDateFormat:@"MM/dd/yyyy 'at' hh:mm a"];
NSString *dateString = [formatter stringFromDate:date];

CGRect screenRect = [[UIScreen mainScreen] bounds];
CGFloat screenWidth = screenRect.size.width - 65.0;

NSString *comments = NSLocalizedString(@"Please write your comments below:", nil);
NSString *build = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];
NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];
NSString *appName = [[[NSBundle mainBundle] infoDictionary] objectForKey:(NSString*)kCFBundleNameKey];
NSString *deviceModel = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
NSString *iOSVersion = [[UIDevice currentDevice] systemVersion];

NSString *emailBody = [NSString stringWithFormat:@"<!DOCTYPE html><html><style> .div {background-color: lightgrey; width: %fpx; padding: 10px; border: 5px solid navy; margin: 2px;}</style><body><div class='div'><p><b>App:</b> %@</p><b><p>Device:</b> %@</p><b><p>iOS Version:</b> %@</p><b><p><p>App Version and Build:</b> %@ (%@)</p><b><p>Date:</b> %@</p> </p></div><font color='red'><b>%@</b></font><br><br></body></html>",screenWidth,appName,deviceModel,iOSVersion,version,build,dateString,comments];

[self setMessageBody:emailBody isHTML:YES];

This is the result when getting the message:

Swift version for both separately:

let versionNumber = NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleShortVersionString") as! String
let buildNumber = NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleVersion") as! String

Its included in this repo, check it out:

The value you set in the Xcode target summary's "Version" field is in here:

Swift 3

let version = Bundle.main.infoDictionary?["CFBundleShortVersionString"] as! String

ObjC

NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];

Swift 2

let version = NSBundle.mainBundle().infoDictionary?["CFBundleShortVersionString"] as! String

and the "Build":

Swift 3

let build = Bundle.main.infoDictionary?[kCFBundleVersionKey as String] as? String

ObjC

NSString *build = [[[NSBundle mainBundle] infoDictionary] objectForKey:(NSString *)kCFBundleVersionKey];

Swift 2

let build = NSBundle.mainBundle().infoDictionary?[kCFBundleVersionKey as String] as! String
