  One of the most jarring friction points when adopting Kotlin Multiplatform (KMP) for iOS development is hitting the   Run   button in Xcode, only to be stopped by a cryptic build error:   Task 'embedAndSignAppleFrameworkForXcode' not found in project . This error halts the development loop immediately. It indicates a disconnection between Xcode's build phases and the Gradle tasks responsible for compiling your Kotlin code into an iOS-consumable framework. This guide provides a root cause analysis of why this disconnection occurs and a rigorous, technical solution to fix it permanently. The Root Cause: The Gradle-Xcode Disconnect To understand the fix, you must understand the architecture of a KMP build. Gradle and Xcode are unaware of each other's existence by default. When you configure a KMP module (commonly named  shared ), the Kotlin Gradle Plugin (KGP) dynamically registers tasks based on the targets you define (e.g.,  iosX64 ,  iosArm64 ). Spec...

  There is a specific kind of frustration reserved for mobile developers transitioning to Kotlin Multiplatform (KMP). You have your shared logic compiling perfectly in Android Studio. Your unit tests are green. You open Xcode, hit   Cmd + B , and are immediately greeted by a red error:   "No such module 'shared'"   or a cryptic failure in the script phase   embedAndSignAppleFrameworkForXcode . This is the "Hello World" of KMP configuration issues. It usually isn't a code problem; it is a toolchain orchestration problem. This guide bridges the gap between Gradle and Xcode. We will dissect why the toolchains disconnect, how to verify your architecture targets, and how to permanently fix the "No such module" error using modern KMP best practices. The Root Cause: The Gradle-Xcode Handshake To fix the error, you must understand the build pipeline. Xcode does not know how to compile Kotlin. It relies on a "Run Script" build phase to delegat...
