## TL;DR

The clean fix is to upgrade to Airship SDK 16, where the module was renamed from Airship to AirshipKit, removing the collision, and also update the Apptimize SDK to 3.5.3, which fixed their side. The reporter confirmed the upgrade resolved it.

## Steps

## When to use

You are seeing this: Upgrading Airship iOS SDK from v14 to v15.0.1 breaks compilation with 'DeepLinkDelegate' is ambiguous for type lookup in this context, and Airship.DeepLinkDelegate does not work either since Airship is a concrete class. Use this skill when you run into "Airship SDK 15: DeepLinkDelegate is ambiguous for type lookup".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

Versions mentioned in the source: v15.0.1, 3.5.3. If you are on something much newer or older, the details may have shifted.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
