How quickly can I hire iOS developers through Azumo?

Typically within one to two weeks from first call to first interview. You meet the engineers before they start, and they work your business hours from nearshore time zones aligned with the US.

How do you vet iOS developers?

Beyond Swift fundamentals, we ask for shipping evidence: apps on the App Store, rejection stories and how they were resolved, and Instruments profiling they have actually done. A developer who has never been rejected by App Review has usually never shipped.

Do your iOS developers work in SwiftUI or UIKit?

Both. New work is SwiftUI-first, but most real codebases mix the two, so we vet for engineers who can drop into UIKit when SwiftUI runs out. Objective-C maintenance is available for older estates.

What does it cost to hire an iOS developer through Azumo?

Nearshore iOS developers generally run 40 to 60 percent below equivalent US salaries, billed as a monthly rate that includes management and bench coverage. No recruiting fees, and rates vary with seniority.

What iOS work has Azumo shipped?

Our first client was Twitter: an iOS app deployed at its largest global advertising events. Since then we have shipped iOS work across media, health, and gaming, and the case study is linked on this page.

Can your iOS developers help get my app through App Store review?

Yes. Review rejections are usually diagnosable: guideline violations, metadata problems, or crashes on Apple's test devices. Our engineers have been through review enough times to fix the cause rather than resubmit and hope.

Do you handle both new iOS apps and existing codebases?

Both, and existing codebases are the more common engagement. Engineers join your repo and release process, ship safely from the first sprint, and propose modernization like SwiftUI adoption incrementally instead of as a rewrite.

What if the iOS developer does not work out?

We swap in a replacement from our bench at no recruiting cost. Because Azumo holds the engagement at the company level, project context carries over to the new engineer instead of leaving with the old one.

Our first client was Twitter, and the iOS discipline stuck: Swift, SwiftUI, and releases that survive review. Senior engineers in your time zone.

When to Hire

When Teams Bring in iOS Developers

iOS punishes mediocrity publicly: review rejections, one-star ratings, and refunds all arrive with receipts. Teams usually call us after learning that the hard way, or to avoid it.

Our iOS work goes back to our first client, Twitter, and the discipline stuck. Senior Swift engineers in your time zone. Day to day they work with AI coding tools, spending the saved hours on the parts Xcode cannot autocomplete: architecture, review, and release judgment.

The seat comes with a company behind it: vetting, management, and continuity.

Our Experience

iOS Work We Have Shipped

Twitter was Azumo's first customer: an iOS application deployed at its largest global advertising events, where failure in front of the company's biggest clients was not an option. iOS work has stayed in our core since, across media, health, and gaming. The case study is below.
