How I’d Learn iOS Development
From time to time, people ask me how to learn iOS development. So here we go.
Before you start, be serious about your end-goal. Are you trying to prototype a concept, get funding, and then hire someone else to deal with it? Are you a “generalist” who needs to get up to speed really fast. I’ve got good news: I’ve seen people ship apps in only a few weeks.
But my advice isn’t about optimizing for your first project. I’m thinking more about the long haul. You already know how to program, and you’re ready to invest a good chunk of time mastering iOS development.
Step 1: Pick Something to Build for Yourself
Maybe I’m wired different, but can’t just read a textbook. I need context and practice.
When I’m learning a language, I need a scratchpad for reinforcement. I found Playgrounds invaluable when learning Swift.
For learning iOS from top to bottom, come up with a small app that scratches an itch. If it motives you, it could be a todo list, meditation app, or a weather checker. I’d lean toward something more personal. Hey, maybe an app to help your parents’ business?
Step 2: Study the Languages
Before you understand the platform, know the languages inside and out. Yes, languages is plural.
While Swift has reached critical mass, there’s a whole lot of Objective-C code out there. You don’t need to master every detail of the language, but you should be able to read it. I used to teach Objective-C to engineers in a day. It’s a small language.
Swift: Read Apple’s Swift Programming Language book. If you want a quick introduction, watch Getting Started with Swift, from Apple’s annual developer conference, WWDC.
Objective-C: Apple has a free guide, which gets the job done.
Can’t I use [favorite language]?
There are third-party tools to build apps in JavaScript, C#, whatever. Avoid them like the plague. Most iPhone apps use Swift and Objective-C. All of Apple’s toolchain is optimized for those languages. When your alternative language breaks for mysterious reasons — and it will — you’re on your own.
Most of your time is going to be spent learning Apple’s frameworks, not syntax. The code samples for these frameworks will be in Swift, so you need to learn Swift anyway.
Step 3: Read Apple’s Guides
There is no shortage of third-party books and tutorials and screencasts about iOS development. Some are good, some are bad, and too many are trying to sell you on something you don’t need. The ultimate authority is Apple, and they give away outstanding free content.
Read Start Developing iOS Apps With Swift. Then read every guide in “Where to Go from Here.” Then, if you want to hear a topic phrased differently, browse the WWDC videos. Then, if you want to go in-depth, read the docs.
There are times when third-party authors disagree with Apple. Try Apple’s way, for now.
Step 4: Stop reading. Just build your app.
You’ve absorbed everything Apple has given you? You can tell me what MVC is? What a UIView does? You know how to Google when you get stuck?You’ve got everything you need. Go build your app.
Seriously. Just go build it.
