Get the version and build number for your app. This is especially useful to track version / builds on the AppStore / TestFlight.

ApplicationInfo.swift

import Foundation

class ApplicationInfo {
    class func getVersionBuildNumber() -> String {
        guard let version = Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString"),
            let build = Bundle.main.object(forInfoDictionaryKey: "CFBundleVersion")
            else {
                fatalError("no version info")
        }
        return "\(version) (\(build))"
    }
    
    class func getAppName() -> String {
        guard let appName = Bundle.main.object(forInfoDictionaryKey: "CFBundleDisplayName") as? String else {
            fatalError("what? no app name")
        }
        return appName
    }
}

/*
If you're missing this CFBundleDisplayName add the following to the Info.plist 

<key>CFBundleDisplayName</key>
<string>CareerView</string>
