HWS Swift Coding Challenges Real Problems Real Solutions


You should have at least 6 months of Swift training under your belt
You should have built some of your own Swift apps, or taken the Hacking with Swift course before starting this coding challenge course


Swift Coding Challenges is produced from the “Hacking with Swift” series of tutorials, which are written and authored by the award winning Swift programmer, Paul Hudson, and these videos were made with his permissionand support. You can always be guaranteed you’re learning the latest and greatest Apple technologies in the HWS tutorials. Hacking with Swift is one of the most popular Swift tutorial series online, which uses an approach that teaches you Swift programming incredibly quickly, and you end up with a huge library of finished projects that are yours to develop further, or ship to the App Store. Paul has received high praise from the creator of the Swift language, Chris Lattner, for his outstanding method of teaching, and series of Swift tutorials. And working together with iOS developer Steve DeStefano, the Hacking with Swift series of programming training videos are simply the fastest way to learn how to code in the Apple eco-system. Note: Section 2 has the Swift 5 update for all the challenges, questions and answers.Check out all of Paul Hudson’s Swift tutorials and books at HackingWithSwift This course is designed to get you ready for your iOS job interview, and for that whiteboard test. All these challenges are real world examples that you can expect to see in an actual iOS interview. And if your not looking for a job, than these challenges are a great way to level up your current iOS skills, and get a great library of coding solutions for your reference to boot.You’ll be presented with various challenges to solve, and I’ll be helping you along with hints, as well as the solutions and explanations for each of the challenges. I also provide a complete transcript of each lecture (solution included) for you to download as a text file.And, this course is called Swift Coding Challenges because you will be challenged.
There is no learning without struggle, so if you don’t take the time to watch each challenge and
try it for yourself in Xcode, you’ll never know how you would have fared. Note: This course is not for Swift beginners, so you should have at least six months of Swift
behind you…preferably a year. If you’ve completed Paul Hudson’s Hacking with Swift instructional tutorials at HackingWithSwift dot com, you should to be able to handle the
Easy challenges, and some of the Tricky ones. If you’ve completed his Pro Swift, then you should be able to
handle most of the Taxing problems too. If you consistently struggle with challenges, then you should definitely watch Paul’s Pro Swift
videos too.
