Hey everyone! ๐Ÿ‘‹ Welcome to the fifteenth issue of the iOS CI Newsletter. I hope youโ€™ve all had a fantastic couple of weeks!

I just returned from an amazing trip to Turin where I spoke at Swift Heroes. I want to take this chance to thank the organisers and all hosts for having me and for putting on such an amazing event.

My favourite thing about attending conferences is getting to know people who are passionate about app development and Swift just as much as I am (if not more) and learning from the other amazing speakers and the topics they covered in their talks.

I now have a few days to get some rest and work on the next talks I am giving at App Talks in Manchester and plSwift in Warsaw. Hoping to meet some of you there! ๐Ÿ‘‹

This event can come in very handy to send real-time analytics of your GitHub Actions workflow runs to an external service as I showcase in the article ๐Ÿ“ˆ.

๐Ÿ” ETTrace: A new tool to profile iOS apps

Emerge Tools have recently announced the release of yet another amazing product (they are on fire recently ๐Ÿ”ฅโค๏ธ)! This time they have published an Open Source CLI written in Objective-C and Swift called ETTrace.

The CLI allows you to profile your app locally directly from the command line and aims to be a faster, more reliable and intuitive alternative to Xcodeโ€™s default time profiler instrument. I am yet to try it in one of my apps, but it certainly looks awesome!

๐Ÿ“– The ultimate guide to Jenkins for iOS

Contrary to what most people think and despite its popularity not being at an all-time high, there are a lot of companies and developers out there using Jenkins as their main CI/CD provider in 2023, including Apple themselves!

The truth is that Jenkins is still a very valid solution for businesses and, if youโ€™re looking at learning more about it or setting up the CI/CD for your iOS app with Jenkins, Roger Oba has written an all-you-need-to-know guide about it โœจ.
