Dear sir/madam,
I have no idea Keychain keeps asking the access permission login while deploying to a device. As I checked the Keychain iOS developer private key access control which Always allows access by these applications which has Xcode, codesign, productbuild correctly.
No matter I removed keychain login from /Users/XXXX/Library/Keychains/login.keychain-db or reinstalled Xcode once again, I have no luck at all.
Best regards
