Xcode 16 xcactivitylog is not a valid xcactivitylog file

[mollyIV]

When I run a parse command from Xcode project, I get "xcactivitylog is not a valid xcactivitylog file".

Steps to reproduce:

• use attached POC project: ios_app_with_tests.zip
• remove Xcode Derived Data
• build the POC app xcodebuild build -scheme App -workspace App.xcworkspace -resultBundlePath /path/to/generate/report
• open XCLogParser project in Xcode 16.0 (double-tap on Package.swift)
• create a new CLI scheme and set parse --project App --reporter html in Run/Arguments section
• run it

Actual result:

Error: ~/Xcode/DerivedData/App-bxetwoejuursezbpdfrueoraoqur/Logs/Build/DBC5DD58-60E9-451C-9173-D87738787128.xcactivitylog is not a valid xcactivitylog file
Program ended with exit code: 1

Expected result:

• properly generated HTML report

According to my debugging, the code fails on reading the activity log:

• https://github.com/MobileNativeFoundation/XCLogParser/blob/master/Sources/XCLogParser/loglocation/LogLoader.swift#L29-L30

There are indeed some UTF characters in the activity log.

What's interesting if I executed the same steps and use xclogparser tool installed locally instead of running it from Xcode, the report is generated properly.

System Info:

• macOS 15.1.1
• Xcode: 16.0
