Get the iOS version of a device programmatically

Question

I want to get the iOS version of the devices which my app is installed on them . Actually I think it is the SDK version of my app . How can I get that by code ? Does it have any function or not ? And also excuse me if I can't explain it good ☹️ .

Use this func for swift 4,

1. Get app version that is in the genral

func getAppInfo()->String {
    let dictionary = Bundle.main.infoDictionary!
    let version = dictionary["CFBundleShortVersionString"] as! String
    let build = dictionary["CFBundleVersion"] as! String
    return version + "(" + build + ")"
}

2. Get app current name that is in general

func getAppName()->String {
    let appName = Bundle.main.object(forInfoDictionaryKey: "CFBundleDisplayName") as! String
    return appName
}

3. Get device iOS version in which app is running.

func getOSInfo()->String {
    let os = ProcessInfo.processInfo.operatingSystemVersion
    return String(os.majorVersion) + "." + String(os.minorVersion) + "." + String(os.patchVersion)
}

Input

    print("OS Version: \(getOSInfo())")
    print("App version: \(getAppInfo())")
    print("App Name: \(getAppName())")

Output:

If you want the String: `ProcessInfo().operatingSystemVersionString` — philipp, Nov 06 '18 at 01:09
