Hello guys.. I finally got the solution to this problem; Unable to install "MyApp"Domain: com.apple.dt.MobileDeviceErrorDomainCode: -402620383--The maximum number of apps for free development profiles has been reached.Domain: com.apple.dt.MobileDeviceErrorDomain Go to the Console app can be found in the Window >> Devices and Simulators >> click the 'Open Console' button in your phone's tab. In the Console app, type "MIFreeProfileValidatedAppTracker" in the upper right corner's search box will help you find the detail of this message after failed running your app. I have also found that most of the bundle IDs shown in the error message are auto offload apps. Turns out the Xcode misclassified all the auto offloaded apps (apps you have not used for a while) as your free developer account's test apps. If you encounter the same problem, the solution is to re-download all the offload apps. Then, turn off the auto offload in the iPhone Settings - iTunes & App Store - Offload Unused Apps to prevent this from happening again.

@jsnee I have only 2 apps under my development profile and I don't understand why the message say that I have exceeded? I have confirmed this by going to: Window>> Devices and Simulators >> Right clicking on my iPhone 11 device >> Show Provisioning Profiles >> I have 2 iOS Team Provisioning Profiles listed for the 2 App IDs. My iPhone 11 device has only one development app installed. However the strange thing is I can run the same app on my older iPhone 6 device without the error.

Same Error Please Assist :( :( Details Unable to install "MyApp" Domain: com.apple.dt.MobileDeviceErrorDomain Code: -402620383- The maximum number of apps for free development profiles has been reached.
