Leaflet helps you learn Swift/SwiftUI and Data Structure/Algorithms better. Leaflet has two main functions: 【1】 Learn Swift/SwiftUI/Combine Learn Swift,SwiftUI+Combine Develop apps and learn Swift language tutorials to help you become a Swift language expert. 【Swift】 Swift one hour very simple micro class, quickly master the core knowledge points of Swift grammar 【Swift Tutorial 】 1. The Swift5 tutorial covers all the features of the language from the beginning to the end 2. The Swift Code Style Guide helps you write more standardized code 3.Swift design pattern practice 4.Swift Algorithm Club Chinese version to learn data structure and algorithm analysis 【Swift + SwiftUI + Combine】 Learn more about Swift + SwiftUI + Combine to help you quickly start your application development journey and master reactive functional programming. Specific advantages of developing with Swift + SwiftUI + Combine: Simple and easy to learn: Swift is a simple and easy-to-learn language, SwiftUI is a declarative UI framework, and Combine is a functional responsive framework. The combination of these three allows developers to develop elegant applications quickly and efficiently. High performance: Swift is a high-performance language, and Combine is a high-performance framework. This set of tools allows developers to develop high-performance applications. Reliability: Both Swift and Combine are developed and maintained by Apple and have good reliability. Extensibility: Both Swift and Combine are extensible frameworks that can meet the various needs of developers. Data binding: SwiftUI provides powerful data binding functions to keep views and data synchronized. Combine's publisher-subscriber pattern allows developers to easily bind data to views. Asynchronous processing: Combine provides rich asynchronous processing functions, allowing developers to easily process asynchronous data. Event handling: Combine can be used to handle various events, such as user interaction, network requests, etc. Testing: Both Swift and Combine provide good testing support that can help developers improve the quality of their applications. Overall, Swift + SwiftUI + Combine is a powerful set of development tools that can help developers develop high-quality, high-performance, and reliable applications. [2] Use Swift language to learn algorithm knowledge The main knowledge contents of data structure and algorithm analysis include: Data structures: arrays, linked lists, trees, graphs, etc. Algorithms: sorting, search, graph search, etc. Algorithm analysis: algorithm complexity, algorithm performance, etc. Data structure and algorithm analysis are the foundation of computer science and the foundation of all computer programs. Mastering data structure and algorithm analysis can enable programmers to write programs more efficiently and improve program quality and performance. 【 Solution 】 The representative algorithm problems are selected, and the relevant data structures and algorithms are analyzed using Swift language Part of the application is based on the open source protocol from the following open source libraries, Gratitude: https://github.com/raywenderlich/swift-algorithm-club , Algorithms and data structures in Swift, with explanations! https://github.com/andyRon/swift-algorithm-club-cn, swift - algorithm - the club's translation. Learn algorithms and data structures using Swift. }

It would be great if I could suggest / give you edits for typos, I.e like a wiki! This app is lovely; I’m sure the explanations can be improved if users have input.

旧版本 题解刷新不出来,更新信版本,收藏都没有了,交互设计都不一样了,以前的熟悉的tab 页,分类,目录都没有了,真的是瞎写啊,这么大的变化,还有历史功能阉割,你看哪个大厂的APP敢这么升级,丝毫没有设计感,不懂得用户体验,一顿瞎改。真正能够用你的APP的都是你的付费用户啊,真的不想在吐槽了,都想自己写一个了,无语ರ_ರ 心塞

I paid for the pro version of leetcodes, and now it is replaced by another app? Seriously?

I've never gotten this app to work. It crashes even before anything loads.

Not even able to open the app. Crashes as soon as it’s launched.

Previous update was disgusting and I was about to uninstall. Latest update on integrating leet code problems is bit relieving. Thanks for this. I’ll suggest you to add settings option with restore purchase based on user level. Such that I can login with all devices.

我以前花钱升级为了pro版本,结果你们上个月突然改版了,我之前付费的内容也不见了。。。开发者也太不道德了,难道不解决一下吗?没有一个合理的解释吗???
