Background App Refresh in iOS: Implementation, Debugging & Pitfalls (Part 2)

divyesh vekariya — Thu, 30 Jul 2026 14:15:00 +0000

You've learned how Background App Refresh works.

Now comes the harder part: making it work reliably.

In this article, I cover:

Implementation best practices
Debugging techniques
Testing strategies
Common mistakes
Why background tasks appear inconsistent

If you've ever wondered why your app refreshes perfectly in development but behaves differently in production, this guide is for you.

Background App Refresh in iOS: Busting the Myths (Part 1)

divyesh vekariya — Fri, 24 Jul 2026 14:45:00 +0000

If you've ever said:

"Background App Refresh doesn't work."

You're not alone.

The challenge isn't the API—it's understanding how iOS decides when your app gets background execution time.

In this article, I cover:

Common myths about Background App Refresh
How iOS actually schedules background work
Why apps behave differently on different devices
The mental model every iOS developer should have

I Asked Claude AI to Predict the FIFA World Cup 2026 Winner... It Got It Right

divyesh vekariya — Mon, 20 Jul 2026 06:53:05 +0000

Before the tournament kicked off, I asked Claude AI a simple question:

Who will win the FIFA World Cup 2026?

Its prediction:
🇪🇸 Spain

Final result:
🏆 Spain became World Champions.

It's an interesting example of how modern LLMs can synthesize public information team strength, historical performance, recent form, and probabilities to generate plausible forecasts.

Of course, one correct prediction doesn't prove AI can predict the future, but it does raise an interesting question:

Where is the line between statistical reasoning and luck?

I documented the prediction before the tournament started:

I'd love to hear your thoughts:
How it made it possible to get that accurate?

Swift Mastery Series — Part 6: Swift Functions

Swift Functions: Everything a Senior iOS Engineer Knows

Functions are one of the first Swift concepts we learn.

Yet they're also one of the easiest to underestimate.

Great function design leads to cleaner APIs, better testability, and more maintainable code.

In this guide, I cover:

Parameter labels
Default & variadic parameters
inout
Function types
Escaping vs non-escaping closures
API design best practices

If you're looking to write Swift that scales beyond small projects, this guide is for you.

Swift Mastery Series — Part 5: Swift Loops

divyesh vekariya — Sat, 04 Jul 2026 15:17:08 +0000

Every Swift developer learns:

for-in
while
repeat-while

But production code tells a different story.

Experienced engineers focus less on "making it work" and more on writing loops that are easy to read, maintain, and reason about.

In this article, I cover:

When for-in is the best choice
Where while still makes sense
Why repeat-while is rarely needed
Common mistakes I see in real codebases
What senior engineers typically prefer

SwiftUI Navigation Transitions Got Better in iOS 27

divyesh vekariya — Sat, 27 Jun 2026 14:30:00 +0000

One of my favorite SwiftUI improvements in iOS 27 is the evolution of NavigationTransition.

Instead of relying on custom animation workarounds, you can now create smoother, more polished navigation experiences with cleaner APIs.

In this article, I cover:

What's new in iOS 27
How the updated API works
Practical code examples
Migration tips from earlier versions

If you're building SwiftUI apps, it's definitely worth checking out.

Swift Mastery Series — Part 4: Swift Conditionals

divyesh vekariya — Sun, 21 Jun 2026 03:38:43 +0000

Swift Conditionals: if, switch, guard & Pattern Matching

Most developers learn if, switch, and guard within their first few days of Swift.

But mastering them takes much longer.

The right conditional can:

Reduce nesting
Improve readability
Simplify complex logic
Make code easier to maintain

I put together a guide covering Swift conditionals from basic branching to advanced pattern matching techniques.

What if you combined AI, probability, and football?

I used Claude to simulate the 2026 FIFA World Cup thousands of times to see:

The most likely winner
Potential dark horses
Surprise knockout runs
How probabilities shift throughout the tournament

The goal wasn't to predict the future perfectly.

It was to explore how AI can reason about uncertainty, data, and complex outcomes.

How India Is Quietly Becoming the World's Most Important AI Market

The AI conversation is usually centered around model creators.

But the next major story may be AI adoption at scale.

India combines:

A massive developer ecosystem
Hundreds of millions of digital users
Rapid startup growth
Strong demand for AI-powered products

The result is a market that could become one of the most important drivers of AI adoption globally.

I explored the trends, opportunities, and reasons behind this shift.
