From 7b2fc3bba6af83888e8f843ef69f189fc32dc97a Mon Sep 17 00:00:00 2001 From: Rui Marinho Date: Fri, 27 Feb 2026 19:36:49 +0000 Subject: [PATCH 1/7] Add simulator management APIs Add SimctlOutputParser for parsing xcrun simctl JSON output (devices and runtimes) and SimulatorService for high-level simulator operations (list, create, boot, shutdown, erase, delete). JSON parsing handles simctl's flexible typing where booleans may appear as strings, based on patterns from Redth/AppleDev.Tools and ClientTools.Platform RemoteSimulatorValidator. Adds System.Text.Json dependency for netstandard2.0 target. Includes 16 tests for the output parser covering device/runtime parsing, edge cases, and the flexible boolean handling.
