Xamarin.Forms: No valid iOS code signing keys found in keychain

Yesterday while creating a new Xamarin.Forms application,  it failed to build for iOS with the following error message:

No valid iOS code signing keys found in keychain

I first thought that there was something wrong with my iOS configuration, but when I tried to create a ‘traditional’ iOS application, it just worked.

On the Xamarin forums I found the following solution that worked for me:

  • Open your Xamarin.Forms projects.
  • Unload the iOS project in Visual Studio.
  • Open the csproj file and search for the following element

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|iPhoneSimulator' ">
    <CodesignEntitlements>Entitlements.plist</CodesignEntitlements>
</PropertyGroup>

  • Remove ‘Entitlements.plist’ from the ‘CodesignEntitlements’
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|iPhoneSimulator' ">
<CodesignEntitlements></CodesignEntitlements>
</PropertyGroup>

Help! I accidently enabled HSTS–on localhost

I ran into an issue after accidently enabling HSTS for a website on localhost. This was not an issue for the original website that was running in IIS and had a certificate configured. But when I tried to run an Angular app a little bit later on http://localhost:4200 the browser redirected me immediately to https://localhost . Whoops! That was not what I wanted in this case. To fix it, you need to go the network settings of your browser, there are available at: chrome://net-internals/#hsts edge://net-internals/#hsts brave://net-internals/#hsts Enter ‘localhost’ in the domain textbox under the Delete domain security policies section and hit Delete . That should do the trick…
