After updating to 1.3.70 I cannot build a project from Xcode, the error is

BUILD FAILED in 1m 19s
16 actionable tasks: 9 executed, 7 up-to-date

FAILURE: Build failed with an exception.

* What went wrong:
Metaspace

Rollback to 1.3.61 solves the problem, although I wanted to use 1.3.70

If you have libraries, you probably need to update them to 1.3.70 versions

I don't think I do

Do you depend on kotlinx-coroutines or kotlinx-serialization for instance? Those need to be bumped up to 1.3.4 and 0.20 respectively. If you’re depending on ktor, that hasn’t been updated yet and you’ll need to stick to 1.3.61 until it is.

If no dependencies, I think you’d need to share more of your config and more error info. I’ve definitely never seen that.

I didn't use any kotlinx-* dependencies, but I've found a solution

org.gradle.jvmargs=-XX:MaxMetaspaceSize=512m

in gradle.properties solved it just fine for me. I actually suspect Gradle 6.2.2, which I bumped along with Kotlin, because now it all works with 1.3.70 and Gradle downgraded to 5.6.1
