Answer 1

See if you have a file called Entitlements.plist if so click on it and check Enable Keychain

or

create a new file names Entitlements.plist with the following content then drag and drop it on your project

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>keychain-access-groups</key>
    <array>
        <string>your bundle id</string>
    </array>
</dict>
</plist>

• Right click on your project

• Choose Options

• Choose iOS Bundle Signing

• Choose Entitlements.plist

Thats all then it should be fine !
