Question

Hello everybody I m new here How can I generate a ` framework` that works in both an iOS device and the simulator Right now I m changing 2 lines in my `build gradle` every time I want to switch between targeting iosX64 simulator and iosArm64 actual device

Cristián Arenas · Answer

These are the 2 lines I change just in case it s relevant ``` iosX64 ios + iosArm64 ios ``` ``` implementation io ktor ktor client serialization iosx64 $ versions ktor + implementation io ktor ktor client serialization iosarm64 $ versions ktor ```

``` select iOS target platform depending on the Xcode environment variables val iOSTarget String KotlinNativeTarget gt Unit gt KotlinNativeTarget = if System getenv SDK NAME startsWith iphoneos == true iosArm64 else iosX64 iOSTarget ios ```

OK if I understand that correctly that ll help me automate this change to generate the correct framework But that does not generate a ` framework` that works on both platforms I need to distribute the framework so it should include appropriate binaries for both architectures Do you know how to achieve this

vanniktech · Answer

Nope Just started with multiplatform this Sunday

Cristián Arenas · Answer

Oh OK don t worry then slightly smiling face

Cristián Arenas · Answer

I may end up using that if I can t figure it out sweat smile It s better than doing it manually

Are you talking about something like described here <https kotlinlang org docs reference building mpp with gradle html building final native binaries> in the Building universal frameworks section

Cristián Arenas · Answer

Oh I think that s exactly what I want I didn t know they were called universal frameworks Thanks heart

tylerwilson · Answer

If you are already using Cocoapods in your project I would suggest going that route use the cocoapods plugin that generates a podspec which you link to from your Xcode project Then when you build your project it will rebuild the framework if needed using the correct current architecture <https kotlinlang org docs reference native cocoapods html>

< Cristián Arenas> One way to build universal framework You may also need to have bitcode enabled and making your framework dynamic

mkojadinovic · Answer

I do something like this ```iosArm64 binaries framework Logger iosX64 binaries framework Logger Create a task building a fat framework task fatFramework type FatFrameworkTask def buildType = project findProperty kotlin build type DEBUG baseName = Logger final File frameworkDir = new File buildDir xcode frameworks destinationDir = frameworkDir from targets iosArm64 binaries getFramework Logger buildType targets iosX64 binaries getFramework Logger buildType ``` Also you have to add next ```iosMain dependencies implementation deps coroutineNative implementation deps kotlinxSerRuntimeNative implementation deps ktoriOS implementation deps ktorSerializationNative SQL Delight implementation deps sqlDelightiOS iosX64Main dependsOn iosMain kotlin srcDirs += project file src iosMain kotlin iosArm64Main dependsOn iosMain kotlin srcDirs += project file src iosMain kotlin ```
