How would you use 12 weeks to learn iOS development?

I’d split the time into phases rather than trying to learn every framework at once. Weeks 1 and 2: get comfortable with Swift fundamentals, including optionals, collections, structs, classes, and protocols. Weeks 3 and 4: learn the basics of UIKit and how an app is structured. Then spend weeks 5 through 8 building a few small apps from a blank project. Make them complete, even if they’re not pretty.

For weeks 9 and 10, add practical features like networking and local data storage, and learn enough Xcode debugging and Instruments to investigate problems. Use the final two weeks to polish one project, write a clear README, and prepare to explain your decisions. That is an ambitious schedule, so treat it as a foundation rather than a guarantee of job readiness.

I’d be cautious about treating UIKit as a required stop before SwiftUI. Both are useful, but with only 12 weeks, pick one to build with consistently and learn the other’s basics later if your goals or job listings call for it. The bigger win is understanding Swift well enough to read errors, break a feature into pieces, and finish something without following a tutorial step for step.

Make a small app early, then keep improving it. A finished project with a clear purpose and a few well-understood features is more useful than a stack of half-completed exercises.

One thing that commonly trips people up is asynchronous work, especially when a screen depends on data arriving from a network request. Start with simple examples, then build a screen that handles loading, success, and failure states. Pay attention to where updates happen and how errors are represented. Don’t just paste in a networking example and move on.

Also, keep the scope small. A basic app that fetches data and presents it cleanly can teach you more than an ambitious app that never gets finished.
