Instruments，随 XCode 一起提供的

同样好奇到底提供啥服务，GitHub.cn ?

支持一下！非常 cool 的技术栈

只是为了说明问题 😂 不严谨, 改成 minute 了。

人肉支持一下

自我检讨，文风太差了。关键信息提取如下：

Ruby 2.6.0 引入了一个新类：Enumerator::ArithmeticSequence 搞崩了 Rails 上的一个方法，但是这个问题已经在 https://github.com/rails/rails/pull/34899 给出了修复。

虽然问题修复了，但是还是有性能问题。所以我们要这么用：(1..200).step(8.seconds) #=> (1..200).step(8.seconds.to_i)

介绍了一个找内存泄漏的方法，参考： https://speakerdeck.com/watson/how-to-optimize-ruby-internal

不过我已经叛逃到 flutter 了

你是部署到 iOS 还是 Android？一般来说，RM 会在苹果发布了新版 SDK 之后一到两周提供支持，可能是还没来得及支持。

贴一下我的 GitHub Actions workflow。

workflow "Build Docker for master branch" {
  on = "push"
  resolves = [
    "Push Frontend Image to Tencent Cloud",
    "Push Backend Image to Tencent Cloud",
  ]
}

  uses = "actions/bin/filter@b2bea0749eed6beb495a8fa194c071847af60ea1"
  args = "branch master"

  uses = "actions/docker/login@c08a5fc9e0286844156fefff2c141072048141f6"
