We are using slather to generate the coverage report. We do see sometimes we are getting issues when generating the coverage and it fails with below error. Based on the error , i see its comes from LLVM Failed to load coverage: Invalid instrumentation profile data (bad magic) error: Could not load coverage information /Users/**/.rvm/gems/ruby-2.7.0/gems/json-2.2.0/lib/json/common.rb:156: warning: Using the last argument as keyword parameters is deprecated /Users//.rvm/gems/ruby-2.7.0/gems/json-2.2.0/lib/json/common.rb:156:in `parse': 785: unexpected token at '' (JSON::ParserError) from /Users//.rvm/gems/ruby-2.7.0/gems/json-2.2.0/lib/json/common.rb:156:in `parse' from /Users//.rvm/gems/ruby-2.7.0/gems/slather-2.4.7/lib/slather/project.rb:135:in `pathnames_per_binary' from /Users//.rvm/gems/ruby-2.7.0/gems/slather-2.4.7/lib/slather/project.rb:124:in `block in profdata_coverage_files' from /Users//.rvm/gems/ruby-2.7.0/gems/slather-2.4.7/lib/slather/project.rb:123:in `each' from /Users//.rvm/gems/ruby-2.7.0/gems/slather-2.4.7/lib/slather/project.rb:123:in `profdata_coverage_files' from /Users//.rvm/gems/ruby-2.7.0/gems/slather-2.4.7/lib/slather/project.rb:98:in `coverage_files' from /Users//.rvm/gems/ruby-2.7.0/gems/slather-2.4.7/lib/slather/coverage_service/cobertura_xml_output.rb:18:in `post' from /Users//.rvm/gems/ruby-2.7.0/gems/slather-2.4.7/lib/slather/command/coverage_command.rb:97:in `post' from /Users//.rvm/gems/ruby-2.7.0/gems/slather-2.4.7/lib/slather/command/coverage_command.rb:59:in `execute' from /Users//.rvm/gems/ruby-2.7.0/gems/clamp-1.3.1/lib/clamp/command.rb:66:in `run' from /Users//.rvm/gems/ruby-2.7.0/gems/clamp-1.3.1/lib/clamp/subcommand/execution.rb:18:in `execute' from /Users//.rvm/gems/ruby-2.7.0/gems/clamp-1.3.1/lib/clamp/command.rb:66:in `run' from /Users//.rvm/gems/ruby-2.7.0/gems/clamp-1.3.1/lib/clamp/command.rb:140:in `run' from /Users//.rvm/gems/ruby-2.7.0/gems/slather-2.4.7/bin/slather:17:in `<top (required)>' from /Users//.rvm/gems/ruby-2.7.0/bin/slather:23:in `load' from /Users//.rvm/gems/ruby-2.7.0/bin/slather:23:in `<main>' from /Users//.rvm/gems/ruby-2.7.0/bin/ruby_executable_hooks:24:in `eval' from /Users/**/.rvm/gems/ruby-2.7.0/bin/ruby_executable_hooks:24:in `<main>' Has anyone seen that issue?

We are seeing issue when try to run the xcodebuild command using ssh, it fails but when running the same using VNC and open terminal app, it works. Anyone seeing the same issue. Any workaround and help is appreciated. Codesign and simulator all works well but fails when run the same commend using ssh. Error: found: Select a different signing certificate for CODESIGNIDENTITY, a team that matches your selected certificate, or switch to automatic provisioning.

Seeing issue with xcode12 when running with older xcode like 11.7 or 11.6. Xcode12 wiping out the older simulators and when running xcodebuild,it throw no simulator found error. watchOS 6.2 (6.2.1 - 17T531) - com.apple.CoreSimulator.SimRuntime.watchOS-6-2 (unavailable, failed to open liblaunchsim.dylib) ==> not available: Error Domain=com.apple.CoreSimulator.SimError Code=401 "The watchOS 6.2 simulator runtime is not available."
