Fix Release Build Issues with the Swift Compiler

:recycle: Current situation & Problem

• Release builds are crashing with a Swift compiler error. It works on debug builds. This is the error message:

  // ...
  1.  Apple Swift version 5.8.1 (swiftlang-5.8.0.124.5 clang-1403.0.22.11.100)
  2.  Compiling with the current language version
  3.  While evaluating request ExecuteSILPipelineRequest(Run pipelines { PrepareOptimizationPasses, EarlyModulePasses, HighLevel,Function+EarlyLoopOpt, HighLevel,Module+StackPromote, MidLevel,Function, ClosureSpecialize, LowLevel,Function, LateLoopOpt, SIL Debug Info Generator } on SIL for SpeziScheduler)
  4.  While running pass #253210 SILFunctionTransform "Devirtualizer" on SILFunction "@$sSaySayxGqd__c7ElementQyd__RszSTRd__lufCXeABQa_s15ContiguousArrayVyADGTg5".
