I work on improving the build time for generating the XCFramework, which later is copied to another directory and used by React UI layer.

Initially, we were using assembleXCFramework which took 3m 30s.
Then I changed it to assembleSharedReleaseXCFramework and the build time decreased to 2m 15s, which is already great. XCFramework generated, files copied all run fine.

But the assembleSharedReleaseXCFramework still runs both tasks linkReleaseFrameworkIosX64 and linkReleaseFrameworkIosArm64 , which take about 65s each.

• We are all on MacBooks M1 in our team. Would you happen to know if we need both tasks to run?
• If I skip linkReleaseFrameworkIosX64 by adding -x linkReleaseFrameworkIosX64 , it runs the first task, but the job fails because XCFramework is not generated.
• Do you think this is the right approach, or do you have suggestions?

it’s all fine with everyone in the team on M1 but then there’s CI with x86 CPU 😬

Not sure exactly how is our CI setup but runner in on Mac Mini M1, but GitLab is hosted on AWS

regarding the approach, I suppose if you configure all targets manually without using the ios() shortcut and simply don’t configure the x64 one, you should get what you’re looking for. Not sure if it’s the best approach though.

Thanks. I added if check for iosArm64 in ios, and seems to do the trick. Build time decreased to 1m 10s which is a 68% boost!

ios {
    binaries.framework {
        baseName = "shared"

        // Add only iosArm64 to the XCFramework
        if ([e-mail](iosArm64())) {
            xcf.add(this)
        }
    }
}

It worked as well by only changing ios {...} to iosArm64 {...} but I thought it may be safer to keep iOS if we want to run a normal iOS app on intel processors later.

Couldn’t you just use the target directly? ios just adds iosArm64 and iosX64. So maybe:

iosArm64("ios") {
    binaries.framework {
        baseName = "shared"
    }
}
