Known Issues

  • 4421 Two Simulators are launching while deploying an iOS App with Xcode10-beta3
  • 4532 Simulator apps with Xcode 10 are not full screen and you can't interact
  • 4305 Default MasterDetail template crashes with Xcode 10 beta 2

Using an older Xcode version

Using an older Xcode version (than the one mentioned in the above requirements) is often possible, but some features may not be available. Also, some limitations might require workarounds, e.g.:

  • The static registrar requires Xcode headers files to build applications, leading to MT0091 or MT4109 errors if API are missing. In most cases enabling the managed linker will help (by removing the API).
