Weird that suddenly I get "A valid provisioning profile for this executable was not found" in Xcode 10. Though the build is successful it fails to run on physical devices. Does anyone face the same problem after updating Xcode to v10?I have valid Enterprise licence for App development.Issue:1. Update installed in Xcode late night yesterday2. Created archieve file (IPA) using distribution profile & certificates3. No issue in IPA installation & usage4. Tried to change the signing to developers profile for debugging5. Build successful6. When tried to run on physical testing device, I get installation error "A valid provisioning profile for this executable was not found"Steps tried:My testing device available in the teamRecreated all the certificatesRecreated profilesInstalled cerificates, profiles on my macCleared all the provision profiles from my testing device & installed the new oneClean build successfullyRun failed with message "A valid provisioning profile for this executable was not found"Solution Found: 1. To change Build System "Legacy Build System" under workspace settings2. This change worked and I was able to run the app on my testing devicesMy Question:Why should I change build system if "New Build System" was successful before the update?
