1You pull a teammate's branch and their new Staging scheme is nowhere in Xcode — where does a scheme live, and what belongs in git?Medium
2Two pull requests touched the project settings and the pbxproj conflict is unreadable — how do xcconfig files change that, and what breaks without $(inherited)?Medium
3Another package cannot import Networking even though that target builds fine and the type is public — what did you leave out of Package.swift?Medium
4CI resolved a newer version of a dependency than your laptop had — what is Package.resolved for, and who on the team should be committing it?Medium
5Twelve modules were converted from static libraries to embedded dynamic frameworks and cold launch got noticeably slower — what changed at load time?Medium
6The console says a class is implemented in both the app and a framework and that one of the two will be used — how did that happen and how do you find it?Medium
7A vendor sent a .framework that runs in the simulator, and App Store Connect rejects the upload for unsupported architectures — what should they have shipped instead?Medium
8Changing one line in a feature module still costs twelve minutes — how do you find out what is actually being rebuilt and which file is genuinely expensive?Hard
9A Debug build takes 40 seconds and Release takes 25 minutes, with one file dominating the log — what is the compiler doing differently?Hard
10Every type in your feature package ended up public because that was the only way to make the app compile — what did that cost, and what should the module expose?Hard
11Checkout must open Profile's address editor and Profile must open Checkout's payment sheet, and SwiftPM rejects the circular dependency — how do you break it?Hard
12You ship your SDK as a pre-built XCFramework — what does turning on BUILD_LIBRARY_FOR_DISTRIBUTION actually commit you to?Hard
13You need to call a C library from a Swift package and the bridging header that worked in the app target is not available — what replaces it?Hard
14Your .ipa is 60 MB, App Store Connect reports 140 MB and a tester's phone downloads 45 MB — which number is real and where does the difference come from?Hard
15SwiftLint, the code generator and the licence script run on every single build even when nothing changed — what is Xcode missing here?Hard
16A 200-target .xcodeproj conflicts on nearly every branch — how do you move to a generated project without freezing feature work?Hard
