My app works perfectly fine on device but not on simulator since the xcode and Mac OS update.
All the frameworks added to project show in red color and when I try to run the app it crash with following error.
dyld[1869]: Symbol not found: OBJC_CLASS$_ACAccountStore Referenced from: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/MapKit.framework/MapKit Expected in: /Users/me/Library/Developer/Xcode/DerivedData/app-dsadygszxtqmitctiebdebgbzedo/Build/Products/Debug-iphonesimulator/Accounts.framework/Accounts
Make sure your framework name do not match with any of system framework. renaming framework helped me resolved this issue.
