I started saving links and planned to add a new “Xcode tips” section to my TIL repo on GitHub<\/a> 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?<\/p>\n

So, that is what I did instead! Say hello to Xcode Tips<\/a>, a resource for the community to find and share<\/strong> their Xcode workflows, tips, tricks, and optimizations. The code for the site is on GitHub<\/a> under the Xcode-Tips organization<\/a>.<\/p><\/blockquote>\n\n

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=none<\/code> option set so that was not the culprit in this case.<\/p>\n

Poking around, I came across this thread<\/a>. 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<\/tt><\/p>\n

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.<\/p>\n<\/blockquote>\n\n
