Forwarded from Telegram Contests
Prize fund: Up to $50,000
Deadline: 23:59 Dubai time on December 26, 2025
Who can participate: Everyone
THE TASK
Implement custom versions of some of the Liquid Glass effects and the relevant interface flows into Telegram for iOS so these appearances work on iOS 18 and older.
You must precisely replicate the animations and look and feel (highlight on tap, scale-up, bounce, and stretching) on the glass elements. This applies in particular to:
– The tab bar
Omit background blur behind the bar itself, while preserving the glass lenses’ ability to blur the bar’s own content.
– Buttons
This includes attach menu icon, voice and video message recording buttons, etc.
– Switches and sliders
Only the moving element itself should apply blur.
Contest Requirements:
– Support for iOS 18 is mandatory.
– No third-party UI frameworks or new dependencies are allowed.
– The submission must be consistent with the existing Telegram for iOS codebase. You may reuse what is already included in the app's codebase.
– Changes must not negatively affect performance, memory usage, or app stability.
Evaluation:
During the evaluation stage, submissions will be tested on a broad range of devices and iOS versions (13-26). In addition to aesthetic accuracy and appeal, we will evaluate:
– Performance;
– Memory consumption;
– Battery impact.
Submissions:
We will announce detailed submission instructions closer to the deadline. The final submission must be your implementation integrated into Telegram for iOS, not a standalone demo app.

Apple Hello Developer, December 2025
1. Meet the winners and finalists of the App Store Awards - the very best and most impactful apps and games on the App Store - and the developers behind them
2. Behind the appealing design of CapWords
This article profiles CapWords, an award-winning AI-powered language learning app that turns photos of real-world objects into animated stickers to teach vocabulary in a playful, engaging way.
It shows how founder Ace Lee was inspired by his 3-year-old daughter and how he used Apple technologies like VisionKit, AVAudioEngine, Neural Voice, and CloudKit to build a fun, privacy-friendly experience for families.
3. Mini Apps Partner Program
This post describes Apple’s Mini Apps Partner Program, which lets developers of host apps that embed web-based mini apps earn 85% on qualifying in-app purchases.
It outlines eligibility requirements, needed technologies (Advanced Commerce API, Declared Age Rating API, In-App Purchase, manifests), and clarifies what counts as a qualifying mini app and purchase.
4. DOCUMENTATION
New in intelligence, security, and accessibility
- Writing code with intelligence in Xcode
Generate code, fix bugs fast, and learn as you go with intelligence built directly into Xcode.
- Browse the latest HIG updates
- Enabling enhanced security for your app
Detect out-of-bounds memory access, use of freed memory, and other potential vulnerabilities.
- Optimizing your app for Assistive Access
Adjust your app’s UI to make sure it works well for people who use Assistive Access.
- EnergyKit
Provide a grid forecast for your app to help people choose when to use electricity.
EnergyKit is an Apple framework that gives apps personalized grid forecasts so people can shift home electricity use (like HVAC and EV charging) to cleaner and potentially cheaper times.
It provides APIs for sending load events (usage data), getting guidance on when electricity is clean or expensive, and retrieving environmental and cost insights, and it currently works only for residential users in the contiguous United States with a special app entitlement.
5. New developer videos
- Learn how apps are integrating the new design and Liquid Glass
- Dailies and mastering for Apple Immersive Video | Colorfront
- Apple Immersive Video-enabled workflows | Blackmagic Design
- Spatial Audio workflows for Apple Immersive Video
- An introduction to capturing Apple Immersive Video
- Meet Apple Spatial Audio Format and APAC
- Meet the Apple Immersive Video format
- Build spatial experiences with RealityKit
- Design immersive and interactive experiences
- Create stories with immersive video and audio
and other videos...

How to optimize videos for iOS
This article is a practical guide for iOS developers and content creators on how to optimize videos for iOS, from capture to playback.
It covers choosing the right formats (MP4 vs MOV) and codecs (H.264 vs HEVC), setting appropriate resolutions and frame rates, and using Swift/AVFoundation code snippets to handle conversion and device-specific settings.
It also walks through camera configuration, compression and editing tools, and best practices for managing heat, battery life, and storage so that videos load quickly and play smoothly across different iPhones and iPads.
P.S. Since the article was published, AV1 has become more relevant on newer Apple devices, but H.264 and HEVC still remain the primary codecs for broad iOS compatibility.

Implementing Non-Consumable In-App Purchases with StoreKit 2
Learn how to start selling Non-Consumable In-App Purchases in your SwiftUI app.
This article explains how to implement a non-consumable In-App Purchase in a SwiftUI app using StoreKit 2, from local StoreKit configuration to showing a product in the UI.
It walks through testing purchases on device, setting up the product in App Store Connect, switching from local config to live products, and verifying everything via TestFlight so you can reliably sell a one-time feature unlock.
