Is possible generate 2 frameworks in different folders but using the same build.gradle file?

I did, but I still need to change the configuration to execute the build twice.  
Arm64 setBuilddir(“arm64build”) Build  
X64 Build  
lipo this framework,this ok, **But too cumbersome**  
Did not find a build out at the same time two framework methods

Have a look at the **FatFrameworkTask** , assuming you build a framework _Foo_, it can be utilized like this (Gradle Kotlin DSL using configuration avoidance API):

```
kotlin {
    iosArm64 { binaries.framework("Foo") }
    iosX64 { binaries.framework("Foo") }

    sourceSets { … }

    tasks {
        register("universalFrameworkDebug", FatFrameworkTask::class) {
            baseName = "Foo"
            from(
                iosArm64().binaries.getFramework("Foo", "Debug"),
                iosX64().binaries.getFramework("Foo", "Debug")
            )
            destinationDir = buildDir.resolve("bin/universal/debug")
            group = "Universal framework"
            description = "Builds a universal (fat) debug framework"
            dependsOn("linkFooDebugFrameworkIosArm64")
            dependsOn("linkFooDebugFrameworkIosX64")
        }
    }
}

```

The task for the release build would look similar…
