Welcome to issue #57 of the iOS Coffee Break Newsletter 📬.

One recurring task I often find myself doing is generating dummy data, both in work-related and personal projects. While it is not particularly time-consuming, it is something I can automate to save a significant amount of time down the road.

So, this week, I put together a guide on building a command-line tool for generating dummy data using the Swift Package Manager. With SPM, creating CLI tools becomes much simpler, especially since we can build them directly in Swift.

Hey everyone. I'm new to mac and Swift and can't figure this out nor find an up to date tutorial specifically for this file format. I used this website to create an app icon and it returned me a .icns file and I don't know how to add it to my app. I'm on macOS 15.6.1 and Xcode 16.4. Dragging and dropping it into xcassets does nothing - it creates a new "AppIcon" entry with the icon but the icon is not applied to the app.

Update: https://discussions.apple.com/thread/250533617?sortBy=rank - this was the solution. I was able to unpack the highest resolution PNG from the .icns package with sips -s format png AppIcon.icns --out icon.png and I then drag and dropped that PNG into Xcode to Assets -> AppIcon -> 1024x1024.

I'm getting a frequent crash due to accessing some array out of bounds somewhere but I can't figure out where. I've looked through the stack trace but all the functions and names I see are internal, I don't recognize any of my functions. Best I can tell is it's occurring during a view redraw (SwiftUI).

FAULT: NSRangeException: *** -[NSMutableIndexSet enumerateIndexesInRange:options:usingBlock:]: a range field {44, -33} is NSNotFound or beyond bounds (9223372036854775807); (user info absent)
libc++abi: terminating due to uncaught exception of type NSException
*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSMutableIndexSet enumerateIndexesInRange:options:usingBlock:]: a range field {44, -33} is NSNotFound or beyond bounds (9223372036854775807)'
terminating due to uncaught exception of type NSException

I believe I need to symbolicate the crash report? But I don't know how to do that and it seems like there should be some obvious process that I'm missing. This is a macOS program.

Any suggestions welcome!

Apparently this is by design. I need a "proper" signing cert or whatevs and I will only get it if I pay 99$ yearly to Apple.

First of all: WTF? I built this app for personal use. Literally I built an app, for myself, and to use it on my computer, I need to pay Apple. Or rebuild it after every reboot. Which is kind of a hassle cause the XCode app is like 7GB and I have to move it from cold storage to disk. Or let it sit and eat up a lot of disk space.

Is there really no loophole here?

In real-world apps, async operations don’t always succeed on the first try — especially when dealing with network calls. Handling retries properly can make your code more resilient, reusable, and testable.

I’ve written an article where I break this down: • A basic retry pattern using async/await • A generic utility function you can reuse across tasks • Thoughts on testing retry logic effectively

👉 Read it here: https://swiftsimplified.co.uk/posts/retry-async-tasks-in-swift/

If you’re building apps with Swift Concurrency, I’d love to hear how you’ve handled retries in your projects. Do you prefer a simple loop, exponential backoff, or a library like swift-retry?

Let me know what you think (and if you would like a promo code).

For reference, I have no idea what I'm doing... I'm building an IOS app with cursor ai and a little help from chatgpt. basically where im at now is I can install my app to my phone, but the core functionality is missing because of the missing replaykit. this is the error message I keep getting:

Provisioning profile "title v5 Broadcast Upload Development" doesn't include the com.apple.developer.replaykit.broadcast entitlement."

I have no idea what to do. I've remade my app groups and profiles literally like 6 times now... I can only handle so much. Does anyone have any advice? Like I said I don't have any idea what I'm doing, so if you need more info lmk

I currently have a view that shows legal documents on tvOS by having you move the focus paragraph by paragraph to read them.

But this only works if you can display an entire paragraph on the screen at once.

Unfortunately, SubscriptionStoreView no longer uses the full screen to show legal documents on tvOS 26. Instead, it makes the view much smaller and so it is likely that some paragraphs will not fit completely in the view.

And so, moving focus paragraph by paragraph will no longer work to allow users to scroll through a long document on tvOS.

Is there an easy workaround?

Hey Swift developers! 👋

If you're like me, you've probably spent countless hours staring at Apple's documentation. While the content is excellent, the monochrome sidebar can make it hard to quickly distinguish between different types of content (Articles, Sample Code, Videos, etc.).

I recently discovered and forked this fantastic Chrome extension by ktiays that adds beautiful, color-coded tags to Apple's documentation sidebar. But I wanted more...

What I Added:

• Extended support to ALL Swift DocC sites - not just developer.apple.com
• Webpack chunk detection - automatically detects any site using Swift's DocC framework
• Works with third-party libraries - Including Point-Free's excellent documentation and any other DocC-generated sites

Before & After:

Features:

• 🎨 Color-coded tags for quick visual scanning
• 🌓 Automatic light/dark mode support
• 📦 Works on ANY DocC site (Apple, Point-Free, your own docs, etc.)
• ⚡ Lightweight and fast - no performance impact
• 🔧 Open source - contribute or customize to your liking!

Installation:

1. Clone/download from GitHub
2. Open Chrome → Extensions → Enable Developer Mode
3. Load unpacked → Select the extension folder
4. Visit any DocC documentation site and enjoy the colors!

Would love to hear your feedback or feature requests! What other documentation improvements would you like to see?

Sometimes changing the cursor does not always work.. Can someone explain this?

Do i need to use something else?

struct SidebarItem: View {

let value: NavItem

let imageName: String

let imageNameWhenSelected: String

let text: String

u/Binding var selectedItem: NavItem?

u/State private var isHovering: Bool = false

private var isSelected: Bool {

selectedItem == value

}

var body: some View {

Button {

selectedItem = value

} label: {

VStack(spacing: 6) {

Image(systemName: isSelected ? imageNameWhenSelected : imageName)

.resizable()

.scaledToFit()

.frame(width: 22, height: 22)

.foregroundColor(isSelected || isHovering ? .darkGreen : .white)

Text(text)

.font(.system(size: 11, weight: isSelected ? .semibold : .regular))

.foregroundColor(isSelected ? .darkGreen : .white.opacity(0.85))

.multilineTextAlignment(.center)

.lineLimit(2)

.minimumScaleFactor(0.7)

.frame(maxWidth: 60)

}

.frame(width: 72, height: 64)

.contentShape(Rectangle())

.scaleEffect(isHovering ? 1.06 : 1.0)

.animation(.spring(response: 0.25, dampingFraction: 0.7), value: isHovering)

}

.buttonStyle(.plain)

.onHover { hovering in

if hovering { NSCursor.pointingHand.push() }

else { NSCursor.pop() }

isHovering = hovering

}

}

}

Hey everyone,
I started picking up Swift recently because I wanted to make a small iOS app for myself. I’m enjoying it, but now I’m second-guessing if it’s worth investing more time.

I’m curious about the industry side of things:

• Are companies still hiring a lot for Swift/iOS devs?
• Or is the trend shifting more toward cross-platform options like Flutter or React Native?

I don’t mind sticking with Swift for personal projects, but if I’m also thinking long-term career, is it still a good skill to double down on?

Hi!

I’m working on a macOS project in which I need to use ImageMagick to convert images (EPS, AI and WebP) and remove metadata from pictures.

Ideally, I would like these libraries to be fully integrated into my code so that the end user doesn’t need to install any dependencies, such as Homebrew.

However, I'm really struggling with this as I already have standalone versions of Ghostscript and ImageMagick, but I'm not sure if I'm doing things properly (I'm new to Mac apps and Swift in general).

Does anyone know the best way to do this?

Thanks a lot!

Alberto

Hey folks,

Clerk team here. We recently pulled the beta tag off our iOS SDK and shipped prebuilt authentication components (Changelog here).

The goal was to make it dead-simple to drop in sign up/sign in, profile, and user management flows without needing to build/maintain them yourself. Under the hood, everything’s just Swift, so you can also go fully custom if that’s your style. Quickstart docs are here if you’d like to take a look: https://clerk.com/docs/quickstarts/ios.

We’re hoping to get honest feedback from iOS devs who try it out:

• How does it feel compared to other auth solutions you’ve used on iOS?
• Do the prebuilt components cover enough of the common cases, or would you still end up rolling your own?
• Anything surprising or frustrating in setup or integration?
• What would make this actually useful in your day-to-day app dev work?

We’re not trying to pitch — we’d genuinely like to know where it’s rough, what’s missing, and how it compares to what you’re already doing. If you give it a try and poke holes in it, that’s exactly the kind of feedback we’re looking for.

You can leave feedback in the thread or drop a note to the team here.

Thanks in advance to anyone willing to kick the tires and share thoughts 🙏

I’m personally not developing an app with Swift, but I wanted to incorporate haptic feedback on my app, and outside of Arc, I have not seen much usage of haptic feedback. I know there are some guidelines for it, but I wanted to get inspired by your implementations. I figured this would be the best place to ask.

[First post here, and I am not used to Reddit yet]
A couple weeks ago, I was studing Redux and playing with parameter packs, and ended up building a package, Onward, that defines a domain-specific language to work with Redux architecture. All this simply because I didn't liked the way that TCA or ReSwift deals with the Redux Actions. I know it's just a switch statement, but, well, couldn't it be better?
I know TCA is a great framework, no doubts on that, accepted by the community. I just wanted something more descriptive and swiftly, pretty much like SwiftUI or Swift Testing.

Any thoughts on this? I was thinking about adding some macros to make it easier to use.
I also would like to know if anyone wants to contribute to this package or just study Redux? Study other patterns like MVI is also welcome.

Hey everyone,

I'm excited to share a project I've been pouring a ton of time into: F1 Swifty, a native companion app for Formula 1 fans on macOS and iOS(would be open-sourced soon).

As a huge F1 fan myself, I wanted a dedicated, high-performance app for my Mac and iPhone that could give me a true "pit wall" experience during the race.

Here are the core real-time features I've been building:

• Live 3D Track Map: See the entire race unfold on a rendered 3D map, tracking every car's position in real-time.

• Real-time Telemetry: A dedicated widget streams crucial data like speed, DRS status, and current gear.

• Live Timing & Leaderboard: The essential tool for any race fan. Keep track of lap times, gaps, and positions for every driver on the grid as it happens.

• Team Radio: Listen in on the drama and strategy with an integrated team radio player.

(I'd recommend embedding your screenshots/GIFs of the app running on macOS or iOS here)

I'm launching with a waitlist first to gather feedback from serious F1 fans and make sure the experience is perfect.

You can sign up now at f1-swifty.com to be one of the first to try it out.

I'm really passionate about this and would love to hear what the F1 and Apple communities think of it so far. Let me know if you have any questions!

I've been working on this project called Fuego that blocks website for me so I can focus (building this is also a distraction from my work right now so go figure) and the code seems fine, claude seems to agree with me that the code is fine, but it's not showing up as a Network Extension in my settings nor is it properly blocking websites from my block list.

What are some ways of debugging this or tutorials for getting this right? I'm a bit stuck since ideally it should be a simple menu bar program

source code for context: https://github.com/jonaylor89/Fuego/

Are you allowed to do this?

let nieuwRecept = Recipe(
    name: "nieuwRecept",
    intro: "A fun Italian pasta dish.",
    servings: 8,
    prepTime: 15,
    nutriscore: 9,
    link: "example.com",
    notes: "Add some sage.",
    tags: [Tag(name: "Tag for new recipe", color: "blue", icon: "apple.logo")],
    steps: ["Cook the ravioli dough", "Then fill with ricotta and spinach."]
)

modelContext.insert(nieuwRecept)

When I try this, the same tag shows up twice under the recipe title.
However, if I close the app and open it again, it only appears once.

What should I do in this case?
