Xcode Tips
I started saving links and planned to add a new “Xcode tips” section to my TIL repo on GitHub to reference later. But as I started, I realized that the resulting markdown file would not be easily discoverable or shareable. I thought, wouldn’t it be nice if the iOS and macOS developer community had a single place to find and share Xcode tips?
So, that is what I did instead! Say hello to Xcode Tips, a resource for the community to find and share their Xcode workflows, tips, tricks, and optimizations. The code for the site is on GitHub under the Xcode-Tips organization.
Looking at my build logs in Xcode (which helpfully show the time for each step), I noticed that code signing was taking up a significant amount of time. Around 3-8 seconds each occurrence, even for standalone binaries. I have quite a few of these as well as frameworks so that time adds up. Note that for debug builds, I had the
—timestamp=noneoption set so that was not the culprit in this case.Poking around, I came across this thread. While I didn’t have the main problem described there of duplicate certificates, buried in that thread was the following advice: trim ~/Library/Preferences/com.apple.security.plist

Apparently, there’s a hidden setting in your project.pbxproj file for copying frameworks where you can specify whether headers get copied over. This is not exposed anywhere in Xcode’s UI, as far as I can tell. It’s also a mystery why it gets set on some targets and not others. The only way to enable/disable this is to edit the project.pbxproj by hand.
TIL: if your Xcode freezes a lot - unpair all devices (Window/Devices and Simulators)
