iOS builds at scale

[jerry @jerrymarino]

Bazel can “compile only” - no link,package, etc with one small trick https://t.co/yZl31dWD3A

@binh Hey @binh! Looking forward to it - details ✅

[jerry @jerrymarino]

It’s official! Bazel-iOS con - the event for devs building iOS apps with #bazel will take place in SF on 9/29. Details / RSVP👇 https://t.co/VDEh82iT0Y

[Patrick Balestra @BalestraPatrick]

At @SpotifyEng we’ve been experimenting with @bazelbuild macOS remote execution over the last year. A few weeks ago we enabled it for our main iOS CI build and decreased our p95 by almost 5x with a cluster of 60 M1 machines. Very impressive stuff!

[jerry @jerrymarino]

@mattrobmattrob Looking forward to it 🎉

[jerry @jerrymarino]

What #bazel optimizations/ features did you pass by given current limits? For me: action avoidance, e2e VFS

[jerry @jerrymarino]

@Javi “live” resume could be nice. Here’s a thread on it https://t.co/6UkRGidtkx

It might need a lot more work

Bazel spawning iOS tests in ephemeral VMs on Apple Silicon https://t.co/LDkv8GPw4D

[jerry @jerrymarino]

@Javi ATM it cold boots them in 10 or so seconds on m1 max. Of course I want millisecond level latency with a hot sim 🚀

[jerry @jerrymarino]

@Javi For UI tests it may be faster on CI if improves reliability + clears state that was previously leaked

[jerry @jerrymarino]

@Javi Glad you like it! No data yet, but perf is good thanks to the para-virt drivers/support

[jerry @jerrymarino]

Imagine swapping “vm” for other runtimes: custom device lab, firebase API call

[jerry @jerrymarino]

@cirrus_labs @rustlang Cool work, thanks for putting this all on GitHub!

[Cirrus Labs @cirrus_labs]

We did some low-level @RustLang to isolate network between Tart's macOS Virtual Machines! 🤓

[The Bazel Show @thebazelshow]

A new episode of #thebazelshow 💚

We discuss with @elliomax the motivation for and the creation and evolution of Bazel-Diff and how it has become a rock solid piece of Tinder’s approach to building & testing mobile applications.

Enjoy and retweet!

Opportunities are endless.
Time is limited, so choose wisely.

[jerry @jerrymarino]

@kastiglione @gnachman @danielpunkass Glad you got it locked down 👌

[jerry @jerrymarino]

@SmileyKeith If only there was some way to get one of these for XCBuild 🤞!

[jerry @jerrymarino]

@rmalik @kyleve @zats @NeoNacho @SmileyKeith Yep use Bazel “tracing” json format and got Square’s iOS build running over 4x faster than before. There are many OSS tools and GUIs to consume it
