Get version number programmatically with Swift

03.10.2022 — iOS, Swift — 1 min read

Following on from yesterday's post about TestFlight is another post today about getting an app's version number programmatically with Swift.

This one is pretty simple too, it's just a matter of reading Bundle's infoDictionary property:

1Bundle.main.infoDictionary?["CFBundleShortVersionString"]

You can create an extension on Bundle like this to make things a little cleaner:

1extension Bundle {
2    var versionNumber: String? {
3        infoDictionary?["CFBundleShortVersionString"] as? String
4    }
5}

I also added another extension to my project to make things even quicker(I usually show this information on the settings screen):

1extension Bundle {
2    var versionNumber: String? {
3        infoDictionary?["CFBundleShortVersionString"] as? String
4    }
5    var formattedVersion: String {
6        "v\(versionNumber ?? "1.0.0")"
7    }
8}

As a bonus you can also get the build number('Build' in Xcode) in a similar fashion:

1extension Bundle {
2    var buildVersionNumber: String? {
3        infoDictionary?["CFBundleVersion"] as? String
4    }
5}
