Swift app development beside our native iOS build
Our native iOS driver app works with no signal, but its case study does not name the language, so we do not claim Swift. We show the build and the versions that matter.

When Swift is the right call
Pick Swift when
- The app must work with no signal
- It captures photos, signatures or location
- Your users all carry iPhones
Look elsewhere when
- You need Android on day one, where we compare React Native and .NET MAUI
- You need a published build that names Swift, which we do not have
- The app is a thin web view

What buyers ask first
Which Swift version is current?
Swift 6.4, announced on swift.org on 15 September 2026, with Swift 6.4.2 available as a point release.
Is your iOS app written in Swift?
The case study calls it native iOS and does not name the language, so we do not claim it. We say what we can show on the first call.
What does the App Store require?
Starting April 2026, apps uploaded to App Store Connect must be built with Xcode 26 or later using the iOS 26 SDK.
Who owns the code and the cloud accounts?
You do, from the first commit. Repositories and cloud accounts stay in your name.
