    To get build date with format 'yyMMddHHmm' you could try this:

    + (NSString *)GetBuildDate {
        NSString *buildDate;
    
        // Get build date and time, format to 'yyMMddHHmm'
        NSString *dateStr = [NSString stringWithFormat:@"%@ %@", [NSString stringWithUTF8String:__DATE__], [NSString stringWithUTF8String:__TIME__]];
    
        // Convert to date
        NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
        [dateFormat setDateFormat:@"LLL d yyyy HH:mm:ss"];
        NSDate *date = [dateFormat dateFromString:dateStr];
    
        // Set output format and convert to string
        [dateFormat setDateFormat:@"yyMMddHHmm"];
        buildDate = [dateFormat stringFromDate:date];
    
        [dateFormat release];
    
        return buildDate;
    }

    Swift3

    static var buildDate: Date? {
        guard let infoPath = Bundle.main.path(forResource: "Info.plist", ofType: nil) else {
            return nil
        }
        guard let infoAttr = try? FileManager.default.attributesOfItem(atPath: infoPath) else {
            return nil
        }
        let key = FileAttributeKey(rawValue: "NSFileCreationDate")
        guard let infoDate = infoAttr[key] as? Date else {
            return nil
        }
        return infoDate
    }
    
    static var prettyBuildDate: String {
        guard let date = buildDate else {
            return "Unknown"
        }
        let formatter = DateFormatter()
        formatter.dateFormat = "yyyy-MM-dd HH:mm:ss ZZZ"
        formatter.timeZone = TimeZone(abbreviation: "UTC")
        return formatter.string(from: date)
    }

    If you redefine __DATE__ and __TIME__ it will make the time update every time you build your app. you won´t need to clean or archive to update the time, just need run the project.

      #define DATE [NSString stringWithUTF8String:__DATE__]
      #define TIME [NSString stringWithUTF8String:__TIME__]
    
    
    - (NSString *)getBuildDate {
        NSString *buildDate;
    
        // Get build date and time, format to 'yyMMddHHmm'
        NSString *dateStr = [NSString stringWithFormat:@"%@ %@", DATE , TIME ];
    
        // Convert to date
        NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
        [dateFormat setDateFormat:@"LLL d yyyy HH:mm:ss"];
        NSLocale *usLocale = [[NSLocale alloc] initWithLocaleIdentifier:@"en_US"];
        [dateFormat setLocale:usLocale];
        NSDate *date = [dateFormat dateFromString:dateStr];
    
        // Set output format and convert to string
        [dateFormat setDateFormat:@"dd/MM/yyyy-HH:mm"];
        buildDate = [dateFormat stringFromDate:date];
    
        return buildDate;
    }

    Swift5

    let compileDate = String(Date())
    let df = DateFormatter()
    df.dateFormat = "MMM-dd-yyyy"
    let usLocale = NSLocale(localeIdentifier: "en_US")
    df.locale = usLocale
    let aDate: Date? = df.date(from: compileDate)

    Try running the script as a build phase step, rather than a scheme pre-action step, so it's run all the time, regardless of the type of build you are producing.

    You might consider using the built-in __DATE__ and __TIME__ macros which will return a string representation of the date and time the app was built. Perhaps they will be of more help to you:

    NSString *dateStr = [NSString stringWithUTF8String:__DATE__];
    NSString *timeStr = [NSString stringWithUTF8String:__TIME__];
