Alamofire (afaik) essentially offers HTTP caching and also supports cache headers, etc. I find that it’s difficult to work with these limitations so always implement the cache layer on top of the networking layer.Luckily, you can really...

I just wrote it in SwiftUI. I have a ModalManager which has an optional modal property. Then, I wrap all the base view like this: ZStack(alignment: .bottom) { content ZStack(alignment: .bottom) { if...

It depends a lot on the app. If your app contains a feed or search, you can end up fetching a lot of data even if it doesn’t contain assets. But, this of course depends on your data structure and use case, so yes, if you expect to never...

Thanks a lot! Fixed it. :)

I recently released an app written 100% in SwiftUI and in doing so, uncovered some patterns that are difficult to express. In this post, I am going to explain how to set initial state in SwiftUI. It’s trickier than you’d expect.First,...

I’m on better internet (finally), so will go ahead and update the article and codebase. Avoiding using the same `Network` object isn’t a great solution because it creates a new `URLSession` for each request. I can’t remember the details,...

Thanks. This is great advice. For simplicity (and the assumption that people won’t be making that many network requests), I’m going to leave the article as is for now (maybe I’ll update it when I get some more time later), but I’ve linked...

Are you referring to the use of a singleton? If so, take a look at my responses to previous comments and let me know what you think:True, but hopefully you can hide as much as you can from the API.Good question. Kay Butter had the same...

Good question. Kay Butter had the same question. Here was my response:I’ve always found for this case a singleton is ok because you actually only ever have one network stack, though dependency injection can be a bit trickier.In your apps,...

Personally, I think the api is terse and understandable, but also extensible. It’s super easy to send a request and get a model back, but with using protocols, it’s also easy to add support for different requests and types.

True, but hopefully you can hide as much as you can from the API. Of course, all code will grow and grow. 😅Interesting point on the singletons. Do you pass around a network stack as a parameter to view controllers? Or how do you manage it...

This is part 2 of a series in writing an elegant and extensible network stack in Swift. You can read part 1 here.Writing your own networking stack is easy! One of the main advantages of owning your stack is that it’s simple to add...

Apple constantly updates their networking APIs to make them easier to use. However, I find that a lot of people still are hesitant to write their own networking layer and choose to rely on common open source solutions.Writing your own...

Offline mode is no longer just an extra feature you could choose to add to your app — it’s something many users expect. I’ve often seen developers force their favorite offline solution on a problem that could be solved in a...

In the card game ‘Bullshit’ (aka ‘Cheat’ or ‘BS’), players can lie about their cards for an advantage. Calling someone’s bluff is risky — if you’re wrong, then you’re punished. Players aren’t incentivised to call bullshit on someone else...

Backend engineers know exactly what’s going on with their services. They know their QPS, memory footprint, error rate, and CPU utilization in real time. They even get paged automatically if there’s a critical error so they can respond...

This post is about one of my favorite brainteasers. I love it for two reasons:It has a surprising but understandable solution.It makes you consider what it means to be rational and logical.The puzzle has a logical solution, but wanted to...

Likely, your app’s onboarding experience isn’t very good. This isn’t because your product isn’t well designed or easy to learn; it’s because building successful onboarding experiences is just hard.todayfm.comA couple of months ago, my...

HORSE may seem like a simple backyard game, but, surprisingly, there is a strategy which improves your chance of winning — and it probably isn’t what you’d expect.HORSE is a popular basketball game where players take turns attempting the...
