iOS app, programmatically get build version

Question

Is there a way to programmatically get the build version of my app? I need to be able to detect when the user has updated the app through the AppStore, in order to execute some code for adjustments

Answer 1

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
