iOS applications

I've built native iOS applications and the services they rely on. This section brings together the parts I can discuss publicly: architecture, authentication, concurrency, security and release reliability. App Store buttons appear only when there is a verified listing I can share.

iPhone & iPad

iOS apps

Apps built for Apple's platforms.

I've made mobile apps and integrations, but not every project has a public store listing. Here are the related experiments and write-ups I can share.

Swift · Security

Device trust & attestation

App Attest, request binding and where client integrity stops being authorization.

Swift · Concurrency

Swift concurrency

Cancellation, lifecycle edges and recovering from asynchronous work that does not cooperate.

Try the trust-boundary decisions instead of just reading about them.

Mobile authorization boundaries

An integrity check is useful. Letting it replace an authorization check is not.
