Hello guys I have just made an app and when I try to run it at my own iPhone even though I connected it physically but it says me build failed. How can I solved it, I made all the settings like: I set the developer users, I set the developer settings at my iPhone. What can I do for solving it?
The usual causes of build errors are errors in your code and missing frameworks. You can see the build errors in Xcode's issue navigator. Press Cmd-5 in Xcode to show the issue navigator.
No one here can give you an answer right now based on the information you provided. For anyone to help you, you must list the errors and show the source code for any compiler errors. Use text, not screenshots, to show your errors and code. Text is easier to read than trying to read text from a screenshot.
The following article may help you get started with fixing the errors in your code:
