Hehas no programming experiences and only knows the overall functions the game must have.You must help him to work out a detailed Graphical User Interface (GUI), design a wellstructuredprogram and implement the program in the Swift programming language. The finalproduct shall be thoroughly tested and ready to be submitted to the App Store.Figure 1. Gameplay Mockup Figure 2. Scoreboard MockupObjectivesThe purpose of this project is to demonstrate competence in the following skills:The full software development cycleiOS App UI and program designiOS UI programmingEffective use of platform APIsProgram testingFunctionality SpecificationThe game is called BubblePop (you can call your app a different name if you wish to). In thisgame, a number of bubbles are randomly displayed on an iOS device screen. A player pops abubble by touching the bubble, and every time they pop a bubble they earn a certain number ofpoints. Bubbles come in five colours: red, pink, green, blue and black. Each colour correspondsto a specific number of points and has a specific probability of appearance (see table 1). Allbubbles appear on the screen briefly (see core functionality 9). A player needs to pop as manybubbles as possible within a certain timeframe (default to 60 seconds) to get high scores. Notethat, if a player pops two or more bubbles of the same colour consecutively, they earn 1.5 timesthe points for the additional bubbles they pop. Finally, game scores are saved and a high scoreboard is displayed after a game run is finished. Figure 1 provides a rough mock up of what themain interface may look like.

You will get 1 functionality markfor each functionality item specified below.Table 1. Specifications for coloured bubblesCore Functionalities1. A player must be able to enter their name before the start of a game run. (You may loadthe players name from the GameKit API if you wish. This extra work is not required.)2. A game timer shall be displayed and it must count down continuously in one-secondintervals. When the timer reaches zero, the game stops.3. A score shall be displayed. It shall be zero initially and shall be updated every time theplayer successfully “pops” a bubble.4. The default timeframe for a game is 60 seconds, i.e. the game timer starts from 60seconds and counts down to 0. This number shall be adjustable in the app settings.5. The maximum number of bubbles displayed on the screen is defaulted to 15, i.e. thereshall be between 0 and 15 bubbles shown on the screen at the same time. This numbershall be adjustable in the app settings.6. The app randomly decides how many bubbles (up to the maximum allowed bubblenumber) shall be displayed on the screen at a time. The bubble colour is decided accordingto the Probability of Appearance in Table 1.7. Bubbles shall be displayed at random positions on the screen with the followingrestrictions:1. The entire bubble shall be displayed within the screen. There shall not be any bubblewith some parts off the screen once it has fully appeared.2. No two (or more) bubbles shall overlap each other.8. When a player touches a bubble, the bubble shall be removed from the screen and thecorresponding game points shall be added to the overall score. For example, if the greenbubble in Figure 1 was touched, it shall disappear and the score shall increase by 5 gamepoints. If two or more bubbles of the same colour are popped in a consecutive sequence,the bubbles after the first one will get 1.5 times their original game points. For example, iftwo black bubbles were popped one after the other, 25 (10 + 1.5 * 10) shall be added tothe total score. Round to the nearest integer if necessary.9. The app shall refresh bubbles displayed every game second. That is, after every gamesecond, the app shall randomly remove a number of bubbles (do not include the bubblesthat have been popped by the player) and replace them with another set of randomlypositioned bubbles. There may be more or less bubbles on the screen compared with theprevious game second subjected to the restrictions in 5 and 6. In this case, randommeans chosen by the program, not the user. So you have a lot of discretion inplacement of new bubbles and selection of old bubbles.10. When the game stops, the player’s score shall be saved in a persistent file (or database)that contains all players’ names and their highest scores.11. At the end of the game, a high score board shall be displayed with the names and scoresof the highest ranking players. (See Figure 2)Extended Functionalities (please do not start on these until finishing CFs)1. In addition to core function 7 and 9, displayed bubbles shall move and go off the screen ifthey are not removed earlier. Their moving speed shall increase as the game timer countsdown. You decide the rate of change with respect to the game timer.2. Animations of game state transitions. For example, one of:1. Flashing count down 3, 2, 1 start at the beginning of play2. Bubbles shrinking, growing, or flying away when removed or tapped3. Score changes or combo lengths displayed with animations in response to taps3. 41889留学生作业代做、iOS Environment作业代做、c/c++，Python语言作业代写、Java编程作业The highest score in the scoreboard shall be displayed during gameplay.4. Any cool and useful features that you can think of.PROGRAM/TEST HINTMake sure your program works under different iOS devices/simulators (e.g. iPhone4s, iPadetc.) with different screen sizes and orientations.For core functionality 4 and 5, the game time and the maximum number of bubbles can beset in the app settings. How can you make sure their settings are valid? How can youprevent a user from setting a negative or a very large number for these settings. Thinkabout how to communicate these constraints to the user in a comfortable way.AssessmentYou will demonstrate your app in your assigned lab on the week of 14 May. Your peers will markyour apps functionality and give you feedback on usability.Max score: 30 marksFunctionality: 20 marks (marked by peers)The Xcode project must unzip successfully and compile without errors.15 marks for specified functionalities.Full marks in functionality requires the completion of all CFs and EFs2 marks for compiling without warnings.1 mark for operating without unhandled runtime errors.2 marks for correct display on different screen sizes and orientations.Code Style: 3 marks (marked by staff)Deduct up to 1 mark for bad or inconsistent indentation, whitespace, or braces.Deduct up to 1 mark for bad or misleading comments.Deduct up to 1 mark for unclear symbol naming.Program Design: 7 marks (marked by staff)Data modeling: Do the data structures reflect the problem domain?Immutable data and idempotent methods: Is the type system used to prevent incorrectcode from being written?Functional separation: Is the problem broken down into meaningful parts?Loose coupling: Can parts be changed in isolation of each other?Extensibility: How easy would it be to add, remove, or change functionality?
