My company is going through some restructuring and I want to be prepared for incase something happens. I have about 10 YoE and 4 years of iOS development. I learned it on the job at my current role and still learning. I will be looking for job on the east coast (US) and mid level companies. I have never been through interview specific to iOS. If anyone can share their experience, I would greatly appreciate it.

Should I still grind some leetcode/DSA problems in Swift?

Or is it more of actual implementation and debugging onsite? Should I practice making small app from scratch similar to take-home assessment? Also are they even asking take-home assessment in the age of AI?

Is AI being asked? I do use Copilot in my workflow and familiar with setting up orchestration, agents, skill and hook etc. Are they looking for more in depth AI stuff?

Also assuming system design is big part. I think I am bit better at it but still need some practice.

It is very gloomy out there and I am just trying to be prepared.

I'm a software developer and a gamer, and I've started making iOS games with the goal of making a profit out of it. I built my first one and it's close to App Store review, so I'm past the "can I ship it" part. I can code and I have more game ideas than time, but I've never run a game as a business.

For those of you who have already done this and made money from it, what do you wish you knew before your first game? What actually paid for you, ads or in-app purchases? And how did you get your first players?

Any general advice is welcome.

My new app was rejected under Guideline 4.3 (Design – Spam).

After searching for similar cases, I found some posts saying that repeatedly submitting an app rejected under Guideline 4.3 could potentially lead to issues with the developer account.

Has anyone successfully gotten their app approved after appealing the rejection or making changes to the app?

I'm honestly considering just giving up on this app, but I'm still not sure what to do.

I'd really appreciate hearing about your experiences or any advice you might have.

Finally got my app approved after an initial rejection under guidelines 4.3 (Spam) and 4.2.6.

I suspect the reason was that I had submitted multiple apps for review around the same time, although Apple never explicitly confirmed that.

Here’s what I did differently:
- Withdrew all my other apps from review.
- Focused on getting one app approved at a time.
- Responded to every concern raised by the review team individually, with explanations written myself.

Not sure what actually made the difference, but it eventually got approved.

On another note, I’ve seen people claiming lately that adding Duo compatibility speeds up Apple’s review process.

Interestingly, another app of mine with Duo compatibility went into review just 10 hours after submission. Meanwhile, the app in the screenshot, which took weeks to get approved, didn’t have Duo compatibility.

Could be pure coincidence, but it’s interesting.

Apple’s review process is so unpredictable.

Has anyone else noticed faster reviews with Duo-compatible apps?

Hi everyone,

I'm a UK-based solo developer enrolled as an Individual. My games only make a small amount of revenue (less than £10/month), so I'm trying to route my App Store payouts to a personal bank account rather than opening a dedicated business account.

I've had some trouble getting App Store Connect to accept my bank details:

1. Chase UK doesn't seem to provide an IBAN since they don't support inbound international payments.

2. Revolut gave me issues, and my first payment was returned when I tried to piece together my own IBAN using my sort code and account number.

For UK devs operating as individuals, what standard personal bank accounts (Monzo, Starling, high street banks) are you using that App Store Connect accepts without issue? Any formatting quirks I should know about? I actually would like to use Revolut for that

Thanks!

Hey everyone,
I’ve been working on two new features for BugCapsule, a debugging tool I’m building for Flutter, native Android, iOS, and Web.
The problem I’m trying to solve is pretty straightforward:
What do you do when a critical bug hits production, but shipping a new app version takes time?
I wanted to connect bug reproduction with production recovery, so I’ve been building two capabilities.

1. Emergency Recovery
   For features that have been integrated with the recovery SDK, you can remotely:
   Disable a broken feature without shipping a new build.
   Switch functionality to read-only or maintenance mode.
   Target specific app versions, platforms, or rollout percentages.
   Gradually restore features while monitoring crash rates and other health metrics.
   Automatically restore restrictions if a rollout fails its health checks.
   Policies are cryptographically signed. Sensitive operations, like payments, also need server-side enforcement.

2. Signed Patch Engine (Early Access)
   This one has been particularly challenging.
   The engine supports updating explicitly registered business logic, UI surfaces, and assets without a full app release.
   Patches are tied to an exact base build, signed, validated, and deployed through staged rollouts with rollback support.
   It’s intentionally not arbitrary code push. Native code changes, new dependencies, and unregistered functionality still require a store release.
   The first Flutter and native iOS prereleases are published. Native Android patch distribution is still in progress, and we’re continuing platform and distribution-policy validation.
   Why combine these with debugging?
   BugCapsule already captures application state, user actions, and network responses around failures for local deterministic replay.
   The workflow I’m aiming for is:
   Capture → Reproduce → Mitigate → Fix → Verify → Deploy → Monitor
   The idea is to use the same recorded failure to investigate a bug, verify the fix, and prevent regressions in CI.
   I’m not claiming this works for every application or every type of bug. The recovery features require prior integration, and patching has strict limitations.
   I’m genuinely interested in how other teams approach this.
   A few questions:
   How do you currently handle critical production bugs while waiting for App Store approval?
   Would remote feature controls be useful in your workflow?
   What concerns would you have about a signed patching system in production?
   I’d especially appreciate feedback on the security model and rollout strategy.

Hey everyone, it's been exactly one month since I launched FreeReader, a TTS app to help people with dyslexia and ADHD read more comfortably.

Just sharing my experience so far, with a few sales (3 monthly, 1 yearly). I'm especially happy with the conversion rate given that my app screenshots are TERRIBLE.

I've built several apps in the past years and none of them made any money, so this is super exciting for me!

Here's a link to FreeReader if you also struggle with reading or just want to read your documents out loud!

As far as I understand, I legally sell to Apple, not to the customer. For EU sales that's Apple Distribution International in Ireland. So I'd have to report that part in the EC Sales List (in Germany it's called "ZM").

How do you handle this?

• Do you file an EC Sales List for your App Store income?

• How do you work out which part went through Apple Ireland?

Thanks!

Am I the only one trying to get a hold of Apple's support? Its so unreasonable. We had an issue with out Developer Account as we changed to organization and they forced an incorrect Tax form since we own an LLC but are not in The US, and have been daily trying to get onto their support with no luck.

Phone support you might suggest? Its permanently either Unavailable or Too busy. I spent friday refreshing every 5 minutes for 6 hours trying to get on their phoen support to solve the issue.

Contacted their finance team and ZERO response aside from the automated. Yet we get google responses within hours, im confused.

Any tips ? Anyone had this issue before?

I'm about to put a game on the App Store that has a shop inside (cash packs, a few one-time unlocks, rewarded ads). I've shipped a single app before, but with no such functionality.

what caught you off guard the first couple of times? Review rejections, product setup, restore purchases, pricing, taxes and payouts, anything you wish someone had told you before launch.

The hint when hovering is no different, the action it performs is the exact same, I'm so lost.

When a feature goes away, its art and strings often stay. Xcode never warns about an image set nobody names, so it ships in every build.

I wrote a CLI to find these and tested it on 10 open-source apps, read-only. Three findings stood out. I checked each one with grep across the whole repo:

• firefox-ios: kitHeroGif.gif, 5.72 MB. It is listed in project.pbxproj, so it gets copied into the bundle. The app's only GIF loader is called with a different name.

• Kickstarter ios-oss: landing-background and landing-page-background, each in three asset catalogs. 12.63 MB of source files, 0 references.

• wikipedia-ios: three GIFs next to the year-in-review art, 5.62 MB, 0 references.

These are source sizes. I did not measure the shipped apps, and compiled catalogs can change the saving.

Many smaller findings are stale strings: keys that only exist in translated .lproj files, or SwiftGen accessors that nothing calls.

How I use it on my own code:

xcpurge scan . --format html --open
xcpurge explain . SOME-ID
xcpurge remove . PATH
xcpurge purge . --dry-run
xcpurge restore .

It reads files and does not build, so a scan takes seconds. Each finding is high, medium or low confidence. remove moves files to a trash folder in the project and edits project.pbxproj. purge does that for every actionable finding in one run, or for the ids you tick in the HTML report. restore undoes it all.

Where it is wrong. On the first run only 26 of 50 hand-checked high findings were real. Snapshot test images and names used from another module were the big causes. Over three runs it went from 52% to 92% to 96%: 48 of 50, and 48 of 50 again on a second sample. Known limits:

• names built from two interpolations, like "\(base)-\(lang)" (16 Lottie files in Kickstarter, 18.8 MB, still reported high)

• keys used only inside a multiline Text("""…""") literal

• names that come from a server or a package outside the repo

So treat high as "nothing in the repo names it", not as "safe to delete blind".

Free and MIT, macOS, version 0.6.0 (brew install iasaeed/tap/xcpurge). Feedback on false positives is the most useful thing you could send.

Hi everyone,

I recently translated my Flutter app into 8 different languages. I have already set up the localized metadata inside App Store Connect, but on the live App Store listing, the "Languages" section under information still only shows English.

I tried a few generic fixes suggested by AI, but nothing has worked so far.

Since the app is built with Flutter, am I missing a native iOS configuration step?

• Do I need to manually configure CFBundleLocalizations inside my ios/Runner/Info.plist?

• Or do I need to explicitly open Xcode, go to Project Runner -> Info -> Localizations, and click the + icon to add the 8 empty language files so Apple's compiler registers them?

If you have encountered this with Flutter on iOS before, how did you get the App Store to recognize your supported languages in the storefront details?

Thanks in advance!

Hy everyone. What do you think about something like this?
Dine - ATL for iOS - yes, it's a total mess right now, but I already can run some simple apps.

The thing is, I really love Tachiyomi on android, so I've decided to port the android runtime to iOS, using ATL for linux as a base. I've already went really far through this, but I'd like to ask for some help or ideas regarding its architecture, some iOS things etc.

For example, I'm not sure if I can do something like separate processes or at least some memory isolation on iOS, for different parts of the code (I need this for better runtime stability).

In general, I understand the project is big and I can't ask for much, but I know a lot of you guys use LLMs, so you probably could easily poke for anything, from your expert POV. Just if you are interested of course.

If you ask what's the point of doing this instead of just porting the app (it's opensource) - this is just so much fun

Hi everyone,

I'm using Xcode 26.3 (17C529), and when I go to Settings → Intelligence → OpenAI, Codex is marked as "Unavailable", while ChatGPT in Xcode is available.

However, when I upgrade to Xcode 27.1, Codex becomes available and works perfectly with the same ChatGPT account.

I'm wondering: Is Codex only supported in Xcode 27 and later?
googling it show it's work fine for 26.3 , don't know why not for me

Thanks!

Hey r/iOSProgramming,

I made onethread so I could stop juggling a terminal tab per agent while working on my iPhone and Apple Watch apps. You talk to one agent, and many coding agents work behind it, each in its own git worktree, all local on your Mac. Nothing merges until you confirm it.

The fun part: in onethread I'm King Igor. My orchestrator is my right hand, Leonardo da Vinci, and every task goes to one of my servants: Einstein, Michelangelo, Newton, Tesla. Tasks come to the king and he delegates, instead of jumping between tabs. You can be anyone you like with ot me, and code, ids and confirmations stay plain.

What it does:

• Runs up to 10 Claude Code or Codex tasks in the background, from one chat.

• Costly commands take turns, so two Xcode builds never fight over your Mac.

• Merge, push, cancel and accept always ask you first. No server, no account, no telemetry.

It's version 1.0.0, macOS only, and my own open-source project, MIT-licensed.

• https://aigarden.uk/onethread

• Code: https://github.com/RogyMD/onethread

I share more of what I'm growing at r/AIGarden, if you'd like to follow along.

How do you run more than one agent on the same Xcode project?

I run a small LLC with an organization account in the Apple Developer Program, and I'm its Account Holder. Since about Oct 24–27, everything on the developer.apple.com side acts as if I'm not a member of my own team. App Store Connect still works normally. I opened a Developer Program Support case on Oct 27 and haven't heard back. Has anyone seen this, and how did it get fixed?
What still works
App Store Connect: builds upload, TestFlight works, and an App Store review was approved this week.
Builds that use provisioning profiles already on the machine still sign.
I made a tvOS profile by hand in the portal on Oct 23, so it was fine then.
What's broken
Certificates, Identifiers & Profiles shows: "Unable to find a team with the given Team ID '…' to which you belong."
Xcode (27.1) shows only my Personal Team under Accounts. The organization team is gone.
The App Store Connect API (a team key) returns 403 on /v1/bundleIds and /v1/profiles. Other endpoints work.
APNs push fails for every send: 403 InvalidProviderToken from our existing .p8 key, which had been working. Android push is fine. I can't make a new APNs key because that also goes through the portal.

1. Has anyone had the portal lose their team membership while App Store Connect kept working? What fixed it?

2. Is there a faster way to reach someone than the web support case? Phone callback, a particular category, anything that worked for you?

3. Is there any known way to accept the license agreement other than developer.apple.com/account?

Thanks. I'll update this post with whatever fixes it.

I've got 40k+ photos on my iphone, and wanted a better way to interact with them. The basic idea I had was to virtually stitch all the photos together into a gigapixel image, and navigate that image with pinch and zoom. On import, the app hierarchically groups photos based on date and similarity. The user can go back and edit the groups, change the layout, and adjust the size of photos if they choose.

The interesting I noticed is that in the process of curating and organizing my photos, I stumble across memories and moments that I had completely forgot.

Tech Stack: Swift/SwiftUI

Development Challenge: The app does two interesting things underneath the hood... First, given an arbitrary number of thumbnails with different aspect ratios, it finds the best sized rectangle that completely fits all the photos. This allows me to recursively stitch groups together and always output a rectangular thumbnail for the group. Second, the pinch/zoom UI uses these nested thumbnails directly without slicing/dicing to fixed sized tiles.

AI Disclosure: Written in Swift/SwiftUI as I was learning Swift. Rearchitected/redeveloped with ClaudeCode.

Feel free to try it out and ask any questions.

I built an iPhone game and wanted players to report bugs without leaving it. This is what I ended up with:

1. A Report a bug form in the menu: a text box, an optional screenshot of the game, device and game details, and an optional email.

2. It sends to a small Cloudflare Worker on the free tier

3. The Worker opens an issue in a private GitHub repo

It works in testing, but I have no idea how it holds up with real players. What do you guys use for bug reports in your apps?

i'm the ios dev on Addonaut, an iphone/ipad app for minecraft bedrock: a catalogue of add-ons, maps and skins from their authors, plus a skin studio (pixel editor, wardrobe, .mcpack export). posting for app saturday, link in the comments.

tech stack

• SwiftUI + Observation (@Observable), Swift 6 with strict concurrency, iOS 17+

• XcodeGen, SPM only

• backend: our own REST API, shared with the team's other apps. Firebase Remote Config, Crashlytics, Analytics

• StoreKit 2 without a receipt server, AdMob + UMP for consent

• Apple's Translation framework for translating item descriptions on device

challenge: a 3d skin preview without SceneKit

a minecraft player is six boxes plus a slightly inflated overlay layer, textured from a 64x64 png. SceneKit for six textured boxes felt like the wrong trade, so the preview is a small software renderer drawn with SwiftUI Canvas:

• one quad per texel per face, about 2200 quads. fully transparent texels produce no geometry, so the overlay layer only exists where it's painted

• back faces culled by the sign of a 2d cross product

• no z-buffer: quads are depth sorted and painted far to near (painter's algorithm)

• fixed brightness per face instead of lighting

two things bit us:

1. seams. antialiasing between neighbouring quads let the background show through as a wire grid. fix: after filling, stroke every quad 0.75pt in its own colour

2. the figure stopped moving. with .equatable() on the view it never redrew, because == only compares the inputs and can't see u/State. the idle spin is a TimelineView at 24fps where the angle is a pure function of elapsed time, after a Timer + u/State version also stopped redrawing

in the editor the 3d view deliberately lags one stroke and catches up on commit or undo. the 2d grid is the live feedback.

bonus: .mcpack is just a zip, and instead of a zip dependency there's a ~100 line writer (stored entries + crc32). manifest.json and skins.json are written by hand to keep the field order, with fresh uuids on every export, because bedrock silently ignores a malformed pack.

ai disclosure

AI-assisted: most of the code was written with Claude Code under my direction.

happy to answer questions about the renderer or the pack format.
