Xcode ios app development code signing

Question

When I run my app into my iphone I have this Warning:

unable to build chain to self-signed root for signer \"\".

My application Installed

Answer 1

1. Change your trust settings of your developer certificate in keychain access to system default
2. Delete all certificates in your local keychain
3. Quit and relaunch xcode
4. Clean
5. Run program on device
6. When it asks, enter your keychain password and click always trust

The issue could be having your certificate set to always trust, that's the issue I had. If you're getting this warning that stops you from running apps on your device, this should fix everything.
