I update to the latest Xcode :
Version 26.1.1 (17B100)
Toolchain: Swift 6.2 Release 2025-09-11 (a)
and MacOS to the latest :
26.1 (25B78)
and still have the same crash problem, I give the crash report to an AI to summarize it :
Primary Issue
Assertion Failure in Scheme Execution: The crash occurred during scheme execution operations, specifically when Xcode was trying to create an execution operation for running a scheme.
Key Technical Details
Crash Location
Thread 0 (main thread) crashed with SIGABRT (Abort trap: 6)
Trigger: Assertion failure in IDEScheme class
Specific Method: -[IDEScheme _executionOperationForSchemeOperationParameters:build:onlyBuild:buildParameters:title:buildLog:dontActuallyRunCommands:restorePersistedBuildResults:deviceAvailableChecker:error:actionCallbackBlock:]
Crash Sequence
Assertion triggered in IDEScheme operations
Assertion handler called abort()
Main thread terminated with abort signal
The crash appears to be an internal Xcode assertion triggered by invalid state during scheme execution preparation, likely related to project configuration or build system state corruption.
