# iOS build fix ## Mode A: Debug-bridge UI-fix ### Contract | Field | Bound contract | |---|---| | Trigger | the user runs /ios-build-fix | | Authority | Reversible local: writes the iOS project's Swift source plus snapshot and screenshot fixtures and the regression test under test/fixtures/ios-fix/, applied and verified through the iOS debug bridge; rollback is version control. No remote mutation. The user picks among competing root-cause fixes. | | Side effect | project code changes edited directly, rebuilt and verified through the debug bridge, plus snapshot and screenshot fixtures and a regression test written under test/fixtures/ios-fix/ | | Done | the failing iOS behavior is fixed and verified on a device or simulator, with a reproducing snapshot and a regression test committed alongside the fix | ### Inputs Required: - A bug finding with a description of the failing behavior, a screenshot, and the suspected accessibility-tree node. Supplied by the user or a prior QA pass. - The iOS debug bridge (StateServer) running with a connected device or simulator, identified by UDID. - The Xcode scheme name and build destination. Optional: - The user's choice among plausible root causes, if more than one remains after source tracing. ### Procedure 1. Do not edit any Swift source until a `GET /state/snapshot` that reproduces the bug is captured. A fix without a reproducing snapshot is rejected. 2. Read the bug finding (description, screenshot, suspected accessibility-tree ...
