How to programmatically display version/build number of target in iOS app?

There are 2 Numbers!

The marketing release number is for the customers, called version number. It starts with 1.0 and goes up for major updates to 2.0, 3.0, for minor updates to 1.1, 1.2 and for bug fixes to 1.0.1, 1.0.2 . This number is oriented about releases and new features. It does not have to stop at 9, 1.11.23 is a reasonable version number.

The build number is mostly the internal number of builds that have been made until then. But some use other numbers like the branch number of the repository or its commit number. This number should be unique to distinguish the different builds, which only have minor incremental changes.

To get the version number:


NSString * appVersionString = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleShortVersionString"];

Swift < 3.0:

let appVersionString: String = NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleShortVersionString") as! String

Swift 3.0:

let appVersionString: String = Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") as! String

To get the build number:


NSString * appBuildString = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleVersion"];

Swift < 3.0:

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

Swift 3.0:

let buildNumber: String = Bundle.main.object(forInfoDictionaryKey: "CFBundleVersion") as! String   

If you want both in one:

You then have to use the use the above lines first.


NSString * versionBuildString = [NSString stringWithFormat:@"Version: %@ (%@)", appVersionString, appBuildString];


let versionAndBuildNumber: String = "\(versionNumber) (\(buildNumber))"


The values in the main bundle are not always present, for example in a command line application there is no CFBundleShortVersionString or CFBundleVersion, so the methods will return nil and it will crash because in the code it makes a incorrect downcast.
But in normal Cocoa iOS and Mac apps these values are defined and will not be deleted.

This is tested with Xcode Version 7.3 (7D175). The build number is often written in parenthesis / braces. The build number is in hexadecimal or decimal.


In Xcode you can auto-increment the build number as a decimal number by placing the following in the Run script build phase in the project settings

buildNumber=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$INFOPLIST_FILE")
buildNumber=$(($buildNumber + 1))
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$INFOPLIST_FILE"

For hexadecimal build number use this script

buildNumber=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$INFOPLIST_FILE")
buildNumber=$(($buildNumber + 1)) 
buildNumber=$(printf "%X" $buildNumber)
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$INFOPLIST_FILE"

For Xcode do the following:

Step 1


Step 2


Step 3


You don’t need to change anything in your project or XCode. Heres the 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:

Here same code for Swift 3:

let versionNumber = Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") as! String
let buildNumber = Bundle.main.object(forInfoDictionaryKey: "CFBundleVersion") as! String
