Hi, I'm Vincent and I've been doing iOS development since 2011 đ On this channel I want to share with you some tips to help you improve your iOS and Swift skills đ©đŒâđ»đ§đ»âđ»
Beginner-friendly intro to adding AI agents to an iOS app in Swift. Explains project setup, integrating an agent/LLM SDK, sending prompts and handling responses, building a simple chat loop, and best practices for API keys, privacy, cost, and latency. Takeaway: an easy path to ship AI features fast.
Avoid a common SwiftUI Spacer mistake. Explains how Spacer() expands to fill remaining space along a stackâs axis, how misplacement can push content off-screen or misalign layouts, and fixes: put Spacer in the correct HStack/VStack, use multiple Spacers to distribute space, and leverage alignment/frame modifiers when appropriate.
Examines whether using SwiftUIâs Group is a good idea. Clarifies that Group is a non-rendering container for structuring view content and conditional branches, not a layout tool. Discusses pros/cons, effects on modifiers and readability, and when to prefer stacks. Takeaway: use Group for organization, not layout.
Debates whether MVVM suits SwiftUIâs declarative, stateâdriven UI. Weighs benefits like separation of concerns and testability against pitfalls such as overâengineering, duplicate state, and unnecessary coupling. Offers guidance on when to keep views simple vs adding a ViewModel. Takeaway: be pragmatic; align with SwiftUIâs data flow.
Learn to hide a viewâs content from screenshots/screen recordings by wrapping it in a secure container via UITextField.isSecureTextEntry (UIKit trick). Builds a reusable wrapper to host any subview. Caveats: non-guaranteed behavior, possible accessibility/keyboard side effects; test on multiple iOS versions. Ideal for sensitive data.
Compares ChatGPT inside Xcode 26 against Cursor and Claude Code for iOS/Swift workflows. Reviews setup and in-IDE experience (chat, inline code completion, refactors, test/docs help), quality and speed, context handling, and integration with Xcode. Takeaway: which assistant best fits everyday iOS dev tasks.
Walkthrough showing how to reveal and use a hidden system prompt in Xcode 26âs ChatGPT integration. Explains how it affects code suggestions and cautions about editing or relying on it. Takeaway: surface the prompt to better steer AI output while understanding its limits.
Outlines strategies to solve SwiftUI performance issues based on insights from Airbnb iOS engineers, with guidance on identifying bottlenecks, reducing view recomposition, and organizing code for efficient updates. Key takeaway: apply targeted optimizations to keep SwiftUI UIs smooth at scale.
Opinionated review of âvibe codingâ in Xcode 26, focusing on how the latest Xcode feels for dayâtoâday iOS development: editor ergonomics, build/run experience, productivity, and rough edges. Weighs pros and cons and offers a verdict on whether upgrading or adopting it now is worthwhile.
Overview of five new AI capabilities in Xcode 26 that streamline iOS development. The video shows how these tools integrate into the editor to speed up coding, navigation, and routine tasks, and discusses when they help vs. when to verify results. Takeaway: use Xcodeâs AI to boost productivity while reviewing suggestions.
Overview of Swift 6.2 changes influenced by developer feedback. Discusses whatâs updated in the language/compiler, how it affects iOS projects, and considerations when upgrading existing codebases. Takeaway: Swift 6.2 refines Swift 6 adoption by smoothing rough edges based on realâworld developer input.
High-level recap of WWDC25 highlights for iOS developers, centered on key takeaways from the Platform State of the Union. Provides an overview of updates around iOS and Swift and what they may mean for everyday development, helping viewers quickly grasp whatâs new and where to explore next.
Build quick emoji reactions in SwiftUI using the .contextMenu() modifier. Attach a context menu to a view, add Buttons for emoji options, and update state or your model when an emoji is tapped to display the selection. Uses builtâin SwiftUI componentsâno custom popoversâmaking a lightweight, native-feeling reactions UI.
Walkthrough of capturing HTTPS traffic from the iOS Simulator using Proxyman. Covers configuring the Simulator to route traffic through the proxy and enabling HTTPS decryption by installing/trusting certificates. Useful for debugging API calls; notes security implicationsâuse trusted certs only in development.
Overview of Swift 6.1 updates for iOS developers: key language changes, tooling/Xcode integration, performance and safety improvements, and migration considerations. Learn what impacts your SwiftUI/UIKit code, compatibility notes, and how to adopt Swift 6.1 in existing projects.
SwiftUI + StoreKit include built-in paywall UIs, letting you sell without custom views. Demonstrates using SubscriptionStoreView/StoreView to list products and initiate purchases, setting up products in App Store Connect, and reacting to entitlement changes. Notes iOS 16/17 availability and limited styling/customization options.
Discussion on CocoaPodsâ future following an announcement, what it means for iOS projects, and why many teams are moving to Xcodeâs Swift Package Manager. Covers migration considerations (thirdâparty availability, private/binary pods, build times) and takeaways for safely planning a transition.
Overview for iOS/Swift devs on using AIâspecifically Cursorâto improve coding flow: drafting code, explaining snippets, refactoring, and debugging. Highlights prompt strategy, iterating with AI, and validating outputs. Takeaway: use AI as a pairâprogrammer, but verify and keep learning.
Explains Apple openâsourcing Swiftâs build system and its impact on app development: effects on Xcode builds and Swift Package Manager workflows, benefits of transparency and community fixes, potential gains in build reliability/speed, and cautions on compatibility and adoption for existing projects.
