Modern Swift networking uses async/await for cleaner asynchronous code compared to completion handlers. URLSession's async methods like data(from:) make network calls straightforward. I wrap API calls in a service layer with typed responses using Coda

Core Data is Apple's object graph and persistence framework, essential for complex data models and offline support. I define entities and relationships in the .xcdatamodeld file, then generate NSManagedObject subclasses. The NSPersistentContainer enca

MVVM (Model-View-ViewModel) separates concerns cleanly in iOS apps. Models hold data, Views display UI, and ViewModels mediate between them with business logic and state. Views bind to ViewModel properties using Combine or SwiftUI's property wrappers.

Combine provides a declarative Swift API for processing values over time, perfect for handling async events like network requests, user input, and timers. Publishers emit sequences of values, and subscribers receive them. Operators transform, filter,

SwiftUI revolutionizes iOS development with declarative syntax where you describe what the UI should look like based on state. Views automatically update when state changes using property wrappers like @State, @Binding, and @ObservedObject. The @State

Maintenance mode gracefully takes applications offline for updates without showing errors. The php artisan down command activates maintenance mode, showing a default or custom view. The --secret option creates bypass tokens for testing. The --retry he

Macros dynamically add methods to Laravel's macroable classes—Request, Response, Collection, Query Builder, and more. I define macros in service providers' boot() methods. The macro() method accepts a name and closure. Macros access $this context like

Creating Laravel packages enables code reusability across projects. I structure packages with src/ for code, config/ for configuration, and database/ for migrations. Service providers register package components—routes, views, commands, configs. The p

Combining global scopes with database views creates powerful data access patterns for multi-tenancy and security. Global scopes automatically filter all queries for a model—perfect for tenant isolation or active record filtering. I implement the Scope

Route model binding automatically resolves Eloquent models from route parameters, eliminating manual lookups. Implicit binding matches parameter names to model IDs—/users/{user} injects the User model. Custom route keys use getRouteKeyName() to bind b

Soft deletes mark records as deleted without removing them from the database, enabling recovery and audit trails. I add SoftDeletes trait to models and a deleted_at timestamp column. Calling delete() sets deleted_at instead of removing rows. Soft-dele

Laravel's HTTP client wraps Guzzle with a fluent, expressive API for consuming external APIs. The Http facade provides methods like get(), post(), put(), and delete(). I chain withHeaders(), withToken(), and withBasicAuth() for authentication. The ret
